WASHINGTON Prime Minister Syed Yousuf Raza Gilani arrived here on Sunday to participate in the Nuclear Security Summit wherein 47 heads of states as well as governments would brainstorm to ensure security of the nuclear assets in the world. Before the two-day Conference that would start on Monday morning, the Prime Minister held a half an hour meeting with US President Barak Hussain Obama. The meeting was underway at the time of filing of this report. The two leaders were expected to take stock of the issues between the two countries including release of money to Pakistan under the Coalition Support Fund, accelerating bilateral assistance in the follow-up of the recent Strategic Dialogue. Earlier, the Prime Minister and his entourage received VIP protocol at the Andrew Air Base up to the Roosevelt Hotel in Washington DC. Earlier, officials told TheNation that the Summit would evolve multilateral mechanism for ensuring foolproof security of the respective nations nuclear assets. They believe that Pakistans participation in the Summit as a key ally of the US as well as a frontline state in the war against terrorism would brighten prospects of getting a civilian nuclear deal with the US similar to which it gave to India.
