Washington: US Secretary of State Hillary Clinton has asked her Chinese counterpart to begin a dialogue on Pakistan, given that the two countries share close ties with Islamabad, officials familiar with the talks said.

"We have stated this before, but there's clearly urgency given recent developments and also given the close relationship that exists between Pakistan and China," said a senior State Department official on condition of anonymity.

Such a request by Clinton gains significance given the strained relationship between the US and Pakistan in the last few weeks, wherein top Pentagon leadership have accused the Pak Army, the ISI in particular, of helping terrorist outfits.

Pakistan has strongly denied such an allegation.

Clinton met the Chinese Foreign Minister, Yang Jiechi, in New York on the sidelines of the ongoing 66th session of the United Nations General Assembly.
