The conditions are related to Pakistan's support to terrorists and terror outfits.
The US House of Representatives has voted for three legislative amendments to impose tougher conditions for reimbursement of defence funding to Pakistan, making it conditional to Islamabad showing satisfactory progress in the fight against terrorism.
The conditions are related to Pakistan's support to terrorists and terror outfits, about which several top US officials and lawmakers have repeatedly expressed concern about in the past.
All the three legislative amendments to the USD 651 billion National Defence Authorisation Act (NDAA) 2018 were adopted by a voice vote by the lower house of the Congress yesterday.
NDAA-2018, which authorises the annual defence expenses for the fiscal year beginning October 1, 2017 was adopted by the House 344-81.
"Today, Congress took a step forward to end Pakistan's betrayal of the US with the addition of an additional certification requirement," said Poe, a Member of the Foreign Affairs Committee and Chairman of Subcommittee on Terrorism, Nonproliferation & Trade.
"It is well known that Pakistan is a Benedict Arnold ally who supports multiple terrorist organisations, including groups that target Americans working to stabilise Afghanistan.
"But current limitations on military reimbursement funding to Pakistan only apply to one terrorist group: the Haqqani Network," Poe said in a statement.
Pakistan's imprisonment of Afridi presents a serious and growing impediment to the United States' bilateral relations with Pakistan, said the amendment as passed by the House of Representatives.
