Prime Minister Yousaf Raza Gilani told reporters at the Pakistan Institute of Medical Sciences (PIMS) on Friday that Pakistan was reassessing its cooperation with the United States by redefining terms of engagement with the NATO and ISAF forces. The premier said Pakistan wanted to improve its relations with the US as there had been ups and downs in the ties. Responding to a question about the NATO attack on Pakistani security forces, Gilani said the matter was referred to the Parliamentary Committee on National Security to formulate recommendations to redefine relations with the US. “These recommendations will be presented at the joint session of parliament, which will revisit and redefine terms of cooperation with the US and NATO forces in future,” he added. “We are also holding an enquiry into the incident,” he added. Earlier, the prime minister visited PIMS to observe a cataract operation being conducted by Chinese doctors under a programme of the Chinese government titled “Bring Light Tour”. Chinese Ambassador to Pakistan Liu Jian accompanied the prime minister.
