Prime Minister Shahid Khaqan Abbasi reconfirmed Pakistan's commitment to the "war on terror" during a meeting with US Secretary of State Rex Tillerson, saying his country had "produced results" fighting the region's Islamist militants.
Relations between uneasy allies United States and Pakistan have frayed in recent years, with Washington accusing Islamabad of turning a blind eye or helping Afghan Taliban and Haqqani network militants who stage attacks in Afghanistan. Pakistan denies doing so.
President Donald Trump has vowed to get tough with Pakistan unless it changed its behaviour, with US officials threatening further reductions in aid and mooting targeted sanctions against Pakistani officials.
Tillerson, on a tour of Asia and the Middle East, arrived in Pakistan on Tuesday afternoon and met with Abbasi, as well as Pakistan's powerful army chief, General Qamar Javed Bajwa.
"We are committed in the war against terror," Abbasi told Tillerson, as the two men sat facing each other on a long table.
"We have produced results. And we are looking forward to moving ahead with the US and building a tremendous relationship," added Abbasi, who sat next to Bajwa.
During a short part of the meeting available to media, Tillerson told the Pakistani delegation that the nuclear-armed nation was an important US ally in the region.
"(Pakistan is) important regionally to our joint goals of providing peace and security to the region and providing opportunity for greater economic relationship as well," Tillerson said.
US officials say they are frustrated that Afghan Taliban and Haqqani militants are afforded freedom of movement and are able to transport weapons and raise funds inside Pakistan, something their Islamabad counterparts staunchly deny.
On Monday, during a visit to Kabul, Tillerson urged Pakistan to act against safe havens on its soil.
"Pakistan needs to, I think, take a clear-eyed view of the situation that they are confronted with in terms of the number of terrorist organisations that find safe haven inside of Pakistan."
'Worried about govt stability'
On Wednesday during India visit, Tillerson said the United States is concerned that extremist groups are threatening the "stability and security" of the Pakistan government.
The secretary of state, who arrived in New Delhi late Tuesday after a brief and tense stop in Islamabad, said too many extremists were finding sanctuary inside Pakistan to launch attacks on other nations.
He said Pakistan had an interest "in not just containing these organisations but ultimately eliminating" the groups.
"Quite frankly my view, and I expressed this to the leadership of Pakistan, is we also are concerned about the stability and security of Pakistan's government as well," he told reporters in New Delhi.
"This could lead to a threat to Pakistan's own stability. It is not in anyone's interests that the government of Pakistan be destabilised."
