LONDON - With the success of the G20 summit meeting on revival of the global economy under their belt, US President Barack Obama and Indian Prime Minister Manmohan Singh focused on the other burning global issue of terrorism, in particular reference to its manifestations in the South Asian region. They said the talks also focussed on the US new Afghan strategy. The two leaders on Thursday held their first bilateral talks on the sidelines of the summit here and agreed to intensify strategic partnership in all areas, including fighting terrorism. The meeting was attended by large teams of officials from both sides. Addressing a Press conference after the meeting, US President Obama said he made it clear to Indian PM Manmohan that in this nuclear era, even the arch-foes have to co-operate with each other and that both India and Pakistan should initiate constructive dialogue so as to resolve their common problems. He said he had not only shared views regarding terrorism with the Indian Premier but also discussed the joint strategy to deal with terrorists and extremists camps along Pakistan-Afghanistan border, adding that they agreed to deal with this issue effectively. He further said India and Pakistans greatest enemy should be poverty, not each other, adding that he suggested it would make sense for the two nuclear-armed neighbours to have a more effective dialogue. The US President said he was very concerned about extremists on the border between Pakistan and India and urged a cooling of cross-border tensions with an effective dialogue. He stated they discussed the terrorism emanating from Pakistan, but focused more broadly on how the US and India could cooperate on counter-terrorism. The UP President said the US saw India as a global partner and together the two countries could play a critical part in meeting the challenges of the 21st century. Obama said that G20 was a historic event in which the leaders of the rich nation have set the priorities that to cut down the numbers of nuclear weapons, how to deal with South Korean nuclear proliferation, how to bring stability in Afghanistan and to defeat terrorism. He said these are all the responsibilities and challenges for the whole world which we jointly need to face. Obama said as the US President his top priority is to protect the interest of Americans but in this modern age American interests are related with interests of the rest of the world. He said during the time of former President Bush, the US had lost its credibility but now, according to the recent surveys, after the change of government the world is again trusting the American leadership. We should adopt the policy of partnership rather than giving dictation. If we will be kind to the people, the US will rule the world much longer, he stated. He said Europe, Japan, India and China had become economic powerhouses. The US was an important actor on the world stage and our leadership should understand that the world is very complicated thing and America cannot do anything alone, he added. Asked by an Indian journalist of his assessment of the danger posed by extremists coming into the country from Pakistan, Obama said: Obviously we are very concerned about extremists and terrorists who have made camp in the border regions of Pakistan as well as in Afghanistan. But we spoke about it more broadly, in terms of how we can coordinate effectively on issues of counter-terrorism. Obama said that India and Pakistan had more mortal enemies than each other. At a time when perhaps the greatest enemy of both India and Pakistan should be poverty... it may make sense to create a more effective dialogue between India and Pakistan, he said. Addressing a separate news conference, Indian Prime Minister Manmohan Singh said he and Obama had agreed to join forces to fight terrorism. We both agreed that our two countries must work together to counter the forces of terror, he said, adding that they had a global strategic partnership. We both have agreed that there are enormous opportunities to further strengthen our relationship to make this partnership more productive, more durable and diverse, he said. The Indian Prime Minister had his first substantive meeting with the US President during which he said the two countries could strive together in meeting challenges like terrorism. We did discuss the development in Afghanistan and Pakistan, Manmohan told reporters after the meeting. We both agreed that our two countries must act together to counter terror. Conveying Indias keenness to carry forward the Indo-US strategic relationship that has developed over the last five years, Manmohan told Obama that India and the US shared same dreams and same vision and the two countries would like to work together to realise those dreams. To a question whether India was willing to discuss Kashmir with Pakistan, he said: We are willing to discuss all bilateral issues that have bedevilled our relationship. But talks cannot be held if hundreds of people, like in Mumbai, are being killed. The Indian Premier said Pakistan had to convince India that it was absolutely sincere in not allowing its territory to be used for terror acts against India as a minimum precondition for further bilateral talks. He said India had provided Pakistan with all the answers to its queries on the 26/11 terror attacks and the ball was now in Pakistans court on bringing the perpetrators to book. We expect Pakistan to do all that is required to bring the perpetrators (of the terror attack) to book. We have supplied all the answers (to 26/11). The ball is now in Pakistans court, Manmohan said. It has to convince us that it is absolutely sincere that its territory wont be used in acts of terror against India, he said, adding that is the minimum precondition for bilateral talks. India and the US have a global strategic partnership, Manmohan said. We discussed the further growth in our partnership, he said. Obama described Manmohan as a wise and decent man who has done a wonderful job guiding India on a path of economic growth.
