The US announced a $2 billion military aid package for Pakistan on the concluding day of the latest round of US-Pakistan strategic dialogue.
US Secretary of State Hillary Clinton revealed the five-year contract, which is still subject to approval by Congress.
The Obama administration has, however, made it clear that it expects Pakistan to contribute more to the campaign against Islamist militants.
Washington has given Islamabad over $1 billion in military aid per year since 2005; it provided almost $2 billion during the previous fiscal year.
According to US officials, Pakistan require more assistance for the war against militants. Thus unlike previous aid packages that were subject to approval on a yearly basis, the new military aid is a five-year deal.
The package will include equipment required for counter-terrorism and counter-insurgency operations, in addition to other things.
Vali Nasr, an advisor on Af-Pak at the US State Department, said that the fight against Pakistani militants expanded during the last year, but this year's flooding has reversed the progress made by the Pakistani military.
"We believe that we have made a great deal of progress and we believe that that progress has reduced the threat to our homeland, while not eliminating it," said Richard Holbrooke, the US envoy to Pakistan and Afghanistan.
But the US officials have also been disappointed by Pakistan's lack of ability and desire to help.
Earlier this month, a report sent by the White House to Congress criticized the Pakistani military's inability to maintain control of the areas seized from militants, a misstep which means that gains may be temporary.
