ISLAMABAD, Pakistan — In a rare show of unity, the government and opposition joined on Thursday to present the United States with a list of stringent demands, including an immediate end to C.I.A. drone strikes, that were cast in uncompromising words but could pave the way for a reopening of NATO supply lines through the country.

After two and a half weeks of contentious negotiations, the main parties agreed on a four-page parliamentary resolution that, in addition to the drone demand, called on the Obama administration to apologize for American airstrikes in November that killed 24 Pakistani soldiers. It declared that “no overt or covert operations inside Pakistan shall be permitted” — a broad reference that could be interpreted to include all C.I.A. operations.

But on the issue of NATO supply lines, the resolution specified only that arms and ammunition cannot be transported through Pakistan, opening the door to the resumed delivery of critical Afghan war supplies like food and fuel for the first time since the November airstrikes. And in practice, arms and ammunition were rarely, if ever, transported in convoys through Pakistan.

“Today’s resolution will enrich your respect and dignity; I assure you that we will get these enforced in letter and spirit,” Prime Minister Yousaf Raza Gilani told Parliament, although he stopped short of declaring when the supply route would reopen.
