WASHINGTON: The United States and Pakistan deepen their engagement with talks between both civil and military officials as Chairman Joint Chiefs of Staff Committee Gen Zubair Mahmood Hayat arrives in the US capital to attend an international conference on counterterrorism.

In Islamabad, Pakistan will host US Secretary ofState Rex Tillerson on Tuesday for the fourth round of talks aimed at rebuilding ties between the two countries which, until recently, were close allies in the war against terrorism.

In December, Islamabad will host yet another visitor, Defence Secretary James Mattis to review the reconciliation process that began with a meeting between Prime Minister Shahid Khagan Abbasi and US Vice President Mike Pence in New York last month.

The decision to push forward the reconciliation process was taken at that meeting and led to Foreign Minister Khawaja Asif`s visit to Washington two weeks ago.

The third round of talks was held in Islamabad when an interagency US delegation visited the Pakistani capital with details of the new US strategyfor South Asia announced by President Donald Trump on Aug 21.

On a separate platform, the United States invited Gen Hayat to Washington to attend the conference on counterterrorism, creating yet another opportunity for talks, now between defence officials of the two countries. Gen Hayat arrived in Washington on Saturday.

US policymakers believe that direct talks with Pakistani defence officialsare necessary to address their main concern: seeking Pakistan`s assistance in the fight against militants along the Pak-Afghan border.

This will also be the focus of defence secretary`s talks in Islamabad, when he visits the city in December.

Mr Mattis told a Congressional panel early this month that the United States was re-engaging Pakistan to support its efforts to win the Afghan war.
