US Secretary of State John Kerry landed in Pakistan late on Wednesday for a day of talks aimed at easing tensions over US drone strikes while putting pressure on the nuclear armed nation to do more to eliminate militant havens on its territory.
In Pakistan on an unannounced visit, Kerry is also likely to discuss ways to revive deadlocked talks with the Taliban and broader efforts to stabilise neighbouring Afghanistan as US-led forces prepare to pull out most combat troops by late 2014.
"We will discuss with the Pakistanis counter-terrorism, cross-border militancy, the economic agenda and how we can continue to partner in terms of promoting a secure and stable Afghanistan," a senior US official told reporters travelling with Kerry.
Kerry is keen to put a fresh focus on a relationship severely strained by US drone strikes which Pakistan says breach its sovereignty, and the raid by US special forces which killed Osama bin Laden in a Pakistani town in 2011.
Pakistan itself has seen a spate of attacks by the al-Qaeda-linked Taliban across the country since the new prime minister, Nawaz Sharif, was sworn in more than a month ago, raising concerns about regional stability.
The United States, Pakistan's biggest donor, wants Pakistan to come up with a clear plan and to step up its campaign against groups such as the Haqqani network, which regularly attacks US forces in Afghanistan from its mountain hideouts in Pakistan.
It is Kerry's first visit to Pakistan as Secretary of State although he has visited the country in other capacities before.
New chapter
Both sides appear keen to start a new chapter in their relationship. President Barack Obama hailed Sharif's victory in May as a "significant milestone" for Pakistan's democracy.
Speaking on condition of anonymity, an official praised Sharif for taking "pretty remarkable" steps to address domestic economic problems such as crippling power shortages.
"Unlike previous visits, we are not going at a moment of crisis, which has defined the relationship over the last several years, but at a moment of quite unique and aligned interests," said the US official.
Security will be the toughest item on the agenda. The Haqqani network is allied to the Afghan Taliban and has bases in the rugged borderland between Afghanistan and Pakistan where other militant al-Qaeda-linked groups are also based.
Another US administration official said the Haqqani network remained "resilient" despite US sanctions and efforts to choke off its funding.
While the issue of extremist groups operating in Pakistan was a priority for the talks, the official emphasised that the intention was not to tell the Pakistanis what to do.
"They are working on their own counter-terrorism strategy. We just need to wait and see what they come up with internally and how we can coordinate both in our bilateral relationship and with joint cooperation," the official said.
