"This incident should not be allowed to jeopardize the bilateral relationship as Pakistan and US have common interest," she added. US Secretary of State Hillary Clinton also raised with the Prime Minister the issue of Pakistan's participation in the Bonn Conference, the Associated Press of Pakistan reported. Prime Minister Gilani responded that he had promised to refer the matter of Pakistan's participation at Bonn to the Parliament's National Security Committee to German Chancellor Angela Merkel when she raised it with him. The committee has supported the decision of the Cabinet not to participate in the Bonn Conference, the Prime Minister said. Prime Minister Gilani said that Pakistan had played a positive role for peace and stability in the region and had many sacrifices in fighting terrorism. The Parliament was seized of the matter of terms of cooperation with the US. This will ensure national ownership and clarity about the relationship, the Prime Minister added.
