Dalai Lama holds hopes for ultimate resolution of contentious Tibet issue

London, May 8 (ANI): The Dalai Lama is still hoping for a softening of China’s stand on the contentious Tibet issue.

Undeterred by the years of inconclusive negotiations with Beijing over the touchy topic of Tibet’s autonomy, the Dalai Lama said that talks still needed to press ahead, and that there is still a possibility of working out a solution that is consensual.

“So far, dialogue failed, but that does not mean in future no possibility,” the Daily Express quoted Dalai Lama as saying. .

He conceded that years of indecisiveness over the issue of his homeland had left him despondent, but the slight change in mood from the Chinese side has renewed his hope, the report said.

He says that the worldwide awareness about the plight of Tibetans, sympathy amongst the Chinese intelligentsia regarding Tibet and mixed signals from some Chinese leaders in a departure from their hitherto reified stand were the cause of his newfound optimism, it added.

“They are realistic,” he said of the Chinese leadership. “They have the ability to act according to a new reality,” the report quoted him, as saying.

He says he doesn’t mind waiting a decade or two more for a peaceful resolution to the Tibet issue, and prescribes patience to achieve the desired results.

Talks between Chinese representatives and the Dalai’s envoys were restarted in January, however, Beijing stuck to its original stance and summarily rejected the idea of granting autonomy to Tibet.(ANI)

US should end discrimination towards Pak to ink civil nuke deal: Qureshi

Islamabad, May 4 (ANI): Reiterating the country’s long standing demand, Pakistan Foreign Minister Shah Mehmood Qureshi has said that the United States must end its ‘discriminatory’ behaviour and enter into a civil nuclear deal to help it address the massive energy crisis prevailing in the country.

During a meeting with US Congressman Howard Burman, Qureshi said Washington must help Islamabad to resurrect the sluggish economy and issues like the huge electricity and water crises, The Dawn reports.

Qureshi told Burman that the counter-terrorism efforts would not achieve the desired results unless the US provides monetary assistance it has pledged under the Kerry-Lugar Bill and Coalition Support Fund (CSF)

Meanwhile, the US has released the final instalment of 467 million dollars under the CSF as reimbursement for Pakistan for the cost incurred during the counterinsurgency operation in 2009.

The CSF was established by the United States in 2001 to support 27 nations, including Pakistan, for some of the costs they incurred in anti-terror operations. Since 2001, Washington has reimbursed approximately 7.2 billion to various countries.

In addition to the CSF, Pakistan has received a total of four billion dollars in civilian and security assistance from the US over the last three years. (ANI)

Lack of confidence Pak team’s biggest problem: Waqar

Lahore, Mar.30 (ANI): Pakistan cricket coach Waqar Younis has said that the national squad lacks confidence, and it is this problem that he would try to sort out during the three week training camp.

Waqar said he would use the ongoing training camp to build confidence in players ahead of next month’s ICC World Twenty20 in the West Indies.

“Pakistan’s biggest problem is their lack of confidence. They wilt under pressure very easily and quickly despite having services of many talented players in their camp. So, my first task will be to mix with players and raise their morale. I hope to invigorate this team and restore faith among players,” he said.

Admitting that coaching the national squad is not an easy task, Waqar said it would be a challenge for him to lift the side following the dismal tour of Australia.

“Someone had to do the job and I dared to accept it and I assured the nation and the Pakistan Cricket Board (PCB) that I would not disappoint them,” The Daily Times quoted Waqar, as saying.

He also hailed the PCB’s decision to appoint all rounder Shahid Afridi as the captain for the ICC T20 World Championship, and said his positive approach towards the game would help the team.

“Afridi is a player with a positive frame of mind who has been bowling excellently in last two years. His mere presence in the field generates a fighting spirit among the players,” Waqar said.

He said he was confident that both of them would work together to deliver the desired results.

Fielding has been one of the major concern’s for Pakistan in the recent past, and Waqar too is aware of the fact.

“During the camp we will stress on the fielding because in a Twenty20 match, 15-20 runs can make the difference and this you can save through good fielding,” he said.

When asked about his favourites in the T20 World Cup, Waqar said it is hard to predict a winner in the slam bang version of the game , adding : “ Any team who play well on the day can win a Twenty20 match, it’s tough to predict who will win but in my opinion Australia, India and South Africa are playing well.” (ANI)

“Optimistic” Musharraf leaves for London in ‘high spirits’ after Saudi visit

Riyadh, Sep.3 (ANI): Former Pakistan President General Pervez Musharraf has returned to London after his three day visit to Saudi Arabia, and it seems his tour has yielded the desired results.

Musharraf, who had a long one to one talk with King Abdullah amid speculations of yet another Saudi-backed political arrangement in Pakistan, was in ‘high spirits’ after the meeting, sources said.

While the details of the meeting are still behind curtains, sources privy to the developments said Musharraf would disclose his future course of action only after returning to London, but as it transpires Musharraf has succeeded in his aim to ensure a safe return to Pakistan without any fears of being tried for high treason under Article Six of the Constitution.

“Musharraf was in ‘high spirits’. His body language was ‘positive’ and he sounded ‘very optimistic’,” The Dawn quoted sources close to the former general, as saying.

It is worth mentioning here that Musharraf had resigned from the Presidency last year, following an agreement in which Saudi Arabia was one of the guarantors.

The accord says that Musharraf would not be tried in any court. The US and Britain are believed to be the other two guarantors of the agreement, which has been kept secret.

While the Pakistan Muslim League-Nawaz (PML-N) is pushing for Musharraf’s trial under high treason charges, observers believe that it would be naïve to think that PML-N chief and former Prime Minister Nawaz Sharif is unaware about the agreement.

Sources also revealed Sharif may visit Riyadh next week where he is likely to meet King Abdullah bin Abdul Aziz. He will also have meetings with some other Saudi leaders including Prince Mukrin, chief of the Saudi Intelligence Agency. (ANI)

Selja calls for world class tourism infrastructure

New Delhi, Aug 19 (ANI): Kumari Selja has called upon experts and stakeholders in the tourism sector to develop world class tourism infrastructure for putting India’s tourism industry on the world tourism map.

Inaugurating a workshop on the subject here today she said, “We should look at comprehensive development of infrastructure which includes roads, water, sanitation, cleanliness, hygiene, proper lighting, landscape, signages and proper maintenance of tourism destinations and heritage sites.”

She said tourism and hospitality sectors contributes six per cent of the GDP and certain streamlining is required in infrastructure facilities.

The Minister said during the Commonwealth Games 2010 about one lakh visitors are expected in the country and this gives us an opportunity to have a relook on the present status of the physical infrastructure for the tourists.

Selja said, world class tourism infrastructure facilities should not be limited in cities like Delhi but also in far flung areas of the country.

She said her Ministry through rural tourism projects is evolving a system to bring villages of the country on the main tourist map.

“We must set indicators for ourselves to see if everything is going fine on the infrastructure front for the visitors. We have to see tourism industry from the point of view of tourists rather than our officialdom,” she added.

She also said that there must be better inter-ministerial coordination and conversion of scheme for development of infrastructure to have the desired results. (ANI)

British diplomat fails to garner Sharif’s support for Musharraf

Lahore, Aug.13 (ANI): Talks between senior British diplomat Mark Lyall Grant, who is trying to garner the support of Pakistani leaders to prevent former President General Pervez Musharraf from being tried for high treason, and Pakistan Muslim League -Nawaz (PML-N) chief Nawaz Sharif have failed to yield the desired results.

According to sources, the meeting did not result in any ‘fruitful’ outcome over the issue of a possible trial of Musharraf.

Sources said that the PML-N chief told Grant that since the Supreme Court had put the ball in parliament’s court, the party wanted the government to take further action on the issue.

According to the Dawn, Sharif told Grant, who is currently the Director of Political Affairs at the British Foreign Office that the PML-N does want to create more trouble in the country and derail the nation’s democratic set-up.

“What we want is that the PPP should honour its commitment on the 17th Amendment and resolve the issue in the light of the Charter of Democracy,” sources quoted Sharif, as saying.

It may be noted that Grant, who had served as the High Commissioner in Islamabad, had also helped Musharraf escape impeachment by parliament after he was forced to step down.

Grant is also trying to achieve reconciliation between the Pakistan People’s Party (PPP) and the PML-N. (ANI)

Pakistan government’s strategy to “isolate” Mehsud a non-starter: Report

Islamabad, July 15 (ANI): The Pakistan government may have announced an all out war against the Tehrik-e-Taliban Pakistan (TTP) chief Baitullah Mehsud in South Waziristan,but it has so far failed to bring the important Taliban leader Jalaluddin Haqqani on its side as part of its strategy to isolate the warlord, the BBC reports.

While Pakistan Air Force’s fighter jets continue to pound suspected hideouts of the Taliban in South Waziristan, every step to garner support of Haqqani, a key Afghan leader, has failed.

Haqqani has refused to side by the government and isolate Mehsud.

Experts believe that the government’s strategy to disassociate Haqqani from Mehsud would never succeed.

It was Haqqani’s son, Sirajuddin who had played a vital role in uniting three major Taliban leaders – Hafiz Gul Bahadur, Baitullah Mehsud and Mullah Nazir in Waziristan, so it is very hard to believe that he and his father would side by the government, they opine.

The government, through local tribal leaders, is also pushing to alienate Hafiz Gul Bahadur and Mullah Nazir groups from Mehsud, but local tribals said its efforts have failed to yield desired results till now, The Nation reports. (ANI)

Pak Army’s tactics of relying on airstrikes against Mehsud may be ineffective: Report

Lahore, July 12 (ANI): The Pakistan Army might have been planning an all out offensive against Tehreek-e-Taliban Pakistan (TTP) chief Baitullah Mehsud in his stronghold, South Waziristan, but according to a report in an US daily, this planned operation won’t yield the desired results and is unlikely to be effective in eliminating the Taliban leadership.

Failure to gain substantial ground against the Taliban and nab the warlord would certainly disappoint the country’s western allies, a report in the US-based McClatchy newspaper said.

The report said the Pakistan military would rely largely on airstrikes in the operation against Mehsud than the on-ground combat, The Daily Times reports.

But this approach is likely to be ineffective, the report quoted some Pakistani officials and analysts, as saying.

“The nature of the operation is totally different from what we did in Swat,” a top Pakistan Army official said on conditions of anonymity.

“It is just blocking the entrance. Nothing goes in, nothing comes out. We’ll keep punishing the enemy with long arms, air power, Cobra helicopters. The tactics have been reversed. Initially they (the Taliban) used to wear us out, now the army is planning to wear them out,” he added.

The tactics of using air power would not quell militancy completely, and in that case it would certainly raise questions over Islamabad’s ability and commitment against the insurgents, the report said. (ANI)

Sufi Mohammad ‘mysteriously’ resurfaces in Peshawar

Peshawar, July 7 (ANI): After being mysteriously missing for the past two months, the Tehrik Nifaz-i-Shariat-i-Muhammadi chief Maulana Sufi Mohammad has reportedly resurfaced.

A close relative of Sufi Mohammad, Bakht Wahid, claimed that the TNSM chief has arrived here along with his family, but refused to comment on his whereabouts.

Wahid also refused to disclose where Sufi Mohammad would be staying in Peshawar.

“We don’t know where Maulana Sufi and his family were detained,” The Dawn quoted Wahid, as saying.

Mohammad’s son, Rizwanullah also called media houses and said that his father has been released, but he too refused to divulge much detail.

However, the government has said that it has no knowledge about Mohammad’s whereabouts, and don’t know much about his release.

“We were neither privy to his arrest nor are we privy to his release,” a government official said.

According to sources, Mohammad and his family members were taken into protective custody just before the government launched a military offensive against the Taliban and other extremists in the North West Frontier Province’s (NWFP) Swat and Malakand Divisions.

Mohammad and his 12 family members had moved to Mirpur, in Pakistan occupied Kashmir (PoK), where security agencies had taken them into custody, and shifted them to an undisclosed location, sources added.

It may be noted that Pakistan government had released the 80 year old TNSM chief to strike a peace deal with the Taliban, but the government’s attempt failed to yield the desired results, and he went missing days before a full fledged military operation was initiated in the region. (ANI)

Canada, Pakistan to resume officer-training program

Ottawa(Canada),May 20 (ANI): Canada has decided to resume an officer-training program with Pakistan’s military after it was called-off more than a decade ago.

Confirming the report, Canada Defence Minister Peter MacKay said his country would once again start its military-to-military relations with Pakistan which was detached after Islamabad conducted its first nuclear tests in 1998.

“It would be more like an officer-exchange program.So, not so much in terms of us training their officers here, but at a staff college level where you would have seminars and lectures that could occur,” the Globe and Mail quoted Mac Kay, as saying.

Mac Kay is currently in Pakistan to hold talks with his counterpart Ahmad Mukhtar and other top government officials of the country.

When enquired about the international community’s fears that Pakistan is rapidly expanding its nuclear capability, MacKay said it could not be confirmed that Islamabad is expanding nuclear arsenals.

“There was no confirmation that that they were, in fact, adding nuclear weapons to their arsenal,” he said.

MacKay said that during his talks with Mukhtar and other top Pakistan officials he encouraged Islamabad to move away from nuclear proliferation.

“We did talk briefly about the subject insofar as maintaining that Canada, as a non-proliferation nation, encourages Pakistan, along with other countries, to seize upon this opportunity,” he said.

Incidentally, the discussions between both the countries came days after MacKay termed Pakistan as ‘the most dangerous country in the world.’

“I”m extremely concerned. The instability in Pakistan in my view makes Pakistan the most dangerous country in the world,” Mac Kay had said.

He had also pointed out that the operation against the Taliban and Al-Qaeda in Afghanistan would not yield the desired results until the extremists are rooted out from Pakistan, and some greater strides are made in taking on the insurgency in Afghanistan as well.

Canada’s ‘concerns’ are obvious as it also has deployed some 2,800 troops in Afghanistan as part of the US led ‘war on terror’ in the country. (ANI)

PPP says all parties were taken into confidence over Swat offensive

Islamabad, May 16 (ANI): Pakistan’s Parliamentary Affairs Minister Dr Babar Awan has told the National Assembly that all political parties were taken into confidence over the Swat offensive.

“It was also the unanimous voice of media and the civil society to eliminate elements of terrorism,” The Nation quoted Awan, as saying.

Urging political leaders to shun their double standards, Awan said, “Government was criticized over striking Swat peace agreement, and now, we are being criticized over Swat operation.”

He said the government is still open to talking to the Taliban provided they laid down their arms and relinquished violence.

“Tell me to which cave, mountain and the tree we go to hold talks with militants,” he asked.

Earlier, PPP lawmaker Yasmeen Rehman said the country is facing a great threat from militants and that the present situation was like a “state of emergency.” She said that the post-operation situation and the handling of IDPs would be an uphill task for the government, which needed a prudent policy by the government.

PML-Q Riaz Hussain Pirzada expressed his support for the military offensive in the NA.

“I support the government’s decision of military operation in Swat and stern action should be taken against people who are challenging writ of the state,” he said.

PML-Q MNA Khwaja Sheraz Mehmood said that the government should have taken this decision earlier, and if the operation failed to achieve desired results, it would have negative effects.

Another PML-N MNA Dr Darshan criticized the government for summoning the NA session after making a decision to launch operation and asked all the political parties to strengthen hands of the government. (ANI)

Pak ‘most dangerous country in the world’: MacKay

Ottawa (Canada), May 12 (ANI): ‘Extremely concerned’ by the current volatile situation in Pakistan, Canadian Defence Minister Peter MacKay has termed Pakistan as the ‘most dangerous country in the world.’

“I’m extremely concerned. The instability in Pakistan in my view makes Pakistan the most dangerous country in the world,” the Globe and Mail quoted MacKay, as saying.

Addressing a press conference at St. John’s, MacKay said it was very difficult for the Pakistan Army to quell the insurgency that has engulfed the North West Frontier Province (NWFP) of the country.

“As long as insurgency is allowed to foster and to incubate inside Pakistan, the problem remains very real, very difficult,” he added.

acKay said the operation against the Taliban and Al-Qaeda in Afghanistan would not yield the desired results until the extremists are rooted out from Pakistan, and some greater strides are made in taking on the insurgency in Afghanistan as well.

He also highlighted that beside a surge in deployment of troops in Afghanistan, it was also very necessary to cut -off the supply lines of the Taliban, as only then peace and stability could return to the country.

The Pakistani army initiated an offensive against the Taliban last month after insurgents in Swat Valley tried to impose their reign on other neighbouring areas.

The Taliban had established its writ over the Swat Valley about two years ago.

Canada’s ‘concerns’ are obvious as it also has deployed some 2,800 troops in Afghanistan as part of the US led ‘war on terror’ in the country. (ANI)

US-Pak trust deficit hampering financial aid to achieve desired results: Senators

Washington, May 5 (ANI): While the United States is on the heels of announcing a tripled non-military aid of about 1.5 billion dollars for Pakistan, officials in the Obama Administration believes that the trust deficit between both the countries is obstructing the desired results that America wants through these financial assistance.

The Kerry-Lugar Bill, which has the provision for a tripled US non-military aid to Pakistan, also states that the lack of trust between Washington and Islamabad is not letting the huge financial assistance to achieve desired results.

Senior Senators on the panel of the bill, John Kerry and Richard Lugar, in a summary of the bill, have stated that: “The status quo is not working: the United States believes it is paying too much and getting too little, and most Pakistanis believe exactly the opposite.”

The bill, which was introduced before the Congress for its approval recently, also states that while Washington is sincere about its relationship with Islamabad and wants to pull the country out of the crisis, people in Pakistan are skeptical about the efforts.

“Today, most Pakistanis believe the United States will cut and run when it serves our purpose, a belief which undermines our long-term efforts to defeat extremists, foster democratic change, and support transparent and accountable institutions that promote security and stability in Pakistan,” The Nation quoted the bill, as saying.

Pak officers don’t want to fight their own people: US expert

New York,May 3 (ANI): Even though the Pakistan Army has initiated military operation against the Taliban in the North West Frontier Province (NWFP) and has claimed success in some areas, the offensive might not yield the desired results, because Pakistani officers are hesitant to carry out an attack against their own people, a US expert believes.

A retired US Army colonel and author, Ralph Peters said Washington must understand that Pakistani military personnel might be facing problems fighting their own people.

“Pakistani officers just don’t want to fight against their people,” The Daily Times quoted Peters, as saying.

“Our diplomats and generals can’t understand why Pakistan’s million-man military avoids confronting the Taliban as the extremists tear into the country’s flesh,” he added.

Peters, while comparing the struggle in Pakistan with America’s civil war said : “Look to our own history. Along the Indus River, 2009 looks worrisomely like 1861 did on the Potomac, the river which flows through West Virginia and Washington.”

“After the attack on Fort Sumter, President Abraham Lincoln offered command of the Union forces to the most respected officer in the US Army, Colonel Robert E Lee. Lee was not in favour of secession,” he said.

“Lee declined the offer. For all of his patriotism, he felt he couldn’t lift his sword against his native Virginia, against his relatives, friends and neighbours,” Peters said. (ANI)

US senator criticizes Pak over Swat peace deal

Islamabad, May 1 (ANI): A senior US Republican Senator Kit Bond has criticized the Pakistan Government over the Swat peace deal.

Bond said such deals have failed to yield desired results in the past, and are bound to fall short of expectations.

“They (Pakistanis) tried it a couple of years, and it was a failure. I’m afraid anytime you negotiate with terrorists,” The Nation quoted Bond, as saying.

Bond expressed lament that the Zardari Government was ‘regrettably learning lessons the hard way.’

“I personally disagree with the decisions the Zardari Government made to turn over the area of Swat to the Taliban so that they could impose Shari’a law,” he added. (ANI)

Tourism festival organised in Manipur

Imphal, Apr 22 (ANI): The ten-day long Manipur Tourism Festival 2009, organised by the state’s tourism department, witnessed a significant participation of visitors from across the country and abroad.

The festival, which concluded on Tuesday, was aimed at highlighting the art and culture of northeast Manipur state.

Visitors from Thailand, Pakistan, Vietnam and Myanmar expressed great enthusiasm and contributed actively to the festival.

Jim Csuthathip Thavesuk, a stall owner from Thailand hoped that she would get a good response in this festival.

“Last time we took part in an exhibition in Guwahati and many people showed interest in our products because our products are available only at one place. I hope that in this exhibition many people will be interested in our products,” said Thavesuk.

Local visitors like Linda claimed that this festival was better organised than the last festival.

“From the last time its better and well organised. There are stalls from other countries. This way, they are going to learn from us and we are going to learn from them,” said Linda.

The stalls displayed goods and artifacts from other states of India.

The people were impressed by the Manipuri handloom and handicrafts items and paintings on display.

Tourism Department had drawn up attractive packages for the tourists like visits to historical places, expedition to fantastic destinations such as Shiroi Hills, Kangkuli Caves in Ukrul District, Tharon Caves of Tamenglong village, adventure at Lamdan and the Leadership Park in Churachandpur.

Among other sporting events were games of traditional hockey, polo, Mukna (traditional wrestling).

The Department of Tourism is hopeful of this festival yielding the desired results, which in turn would boost the economy of Manipur. By L.C.K. Singh (ANI)

Reconciliation with Taliban only on Afghan Government guidelines: US

Washington, Mar.12 (ANI): United States Defense Secretary Robert Gates has asserted that any settlement with insurgents in Afghanistan must be under terms set by the Kabul Government.

“I think almost all insurgencies in the end game involve political reconciliation. The issue is it needs to be on the terms of the government of Afghanistan,” The News quoted Gates, as saying.

However, he made it clear that the allied forces would continue its offensive against the faction of the outfit which has no interest in reconciliation.

“There are elements of the Taliban that are absolutely irreconcilable and frankly will have to be killed,” Gates added.

Earlier, the Obama administration had said that it was ready to host dialogues with the Afghan insurgents on the lines of its Iraq policy after admitting that the eight year long ‘War on terror’ in the region has not yielded desired results. (ANI)

Scientists explain how maths can bring invisibility cloak closer to reality

Washington, Mar 6 (ANI): Harry Potter’s invisibility cloak may have intrigued many of J.K. Rowling’s fans, and now researchers have come a step closer to realising it, by explaining how mathematics can turn out to be a major tool in the developing field of cloaking.

Ranked the number five breakthrough of the year by Science magazine in 2006, cloaking involves making an object invisible or undetectable to electromagnetic waves.

And now scientists have presented a paper giving an overview of the theoretical developments in cloaking from a mathematical perspective.

One method involves light waves bending around a region or object and emerging on the other side, as if the waves had passed through empty space, creating an “invisible” region that is cloaked.

But for that, the object or region has to be concealed using a cloaking device, which must be undetectable to electromagnetic waves.

Manmade devices called metamaterials use structures having cellular architectures designed to create combinations of material parameters not available in nature.

Mathematics is essential in designing the parameters needed to create metamaterials, and to show that the material ensures invisibility.

The mathematics comes primarily from the field of partial differential equations, in particular from the study of equations for electromagnetic waves described by the Scottish mathematician and physicist James Maxwell in the 1860s.

One of the “wrinkles” in the mathematical model of cloaking is that the transformations that define the required material parameters have singularities, that is, points at which the transformations fail to exist or fail to have properties such as smoothness or boundness that are required to demonstrate cloaking.

But the singularities are removable, which means that the transformations can be redefined over the singularities to obtain the desired results. The authors of the paper describe this as “blowing up a point”.

The paper also suggests that if there are singularities along a line segment, it is possible to “blow up a line segment” to generate a “wormhole”.

The cloaking version of a wormhole allows for an invisible tunnel between two points in space through which electromagnetic waves can be transmitted.

Cloaking via electromagnetic wormholes has many possible applications, which include the creation of invisible fibre optic cables, for example for security devices, and scopes for MRI-assisted medical procedures for which metal tools would otherwise interfere with the magnetic resonance images.

The invisible optical fibres could even make three-dimensional television screens possible in the distant future.

The paper titled ‘Cloaking Devices, Electromagnetic Wormholes, and Transformation Optics’, has been published in SIAM Review. (ANI)
