KABUL, Afghanistan — Fuming over what they have called the Pakistani role in exporting terrorism across the border, Afghan officials signaled on Tuesday that they had little interest, for now, in healing a rift with Pakistan, their eastern neighbor.

Two developments set the tone: In New Delhi, President Hamid Karzai of Afghanistan signed a wide-ranging strategic partnership with India, which Pakistan regards as its principal adversary. Mr. Karzai’s visit also underscored the growing economic and security ties between India and Afghanistan.

And here in Kabul, intelligence officials investigating the assassination of the head of Afghanistan’s peace process said that Pakistan was refusing to cooperate with their inquiry and that it had failed to crack down on Taliban leaders who, the Afghans say, planned the killing from inside Pakistan.

The moves were all but certain to draw further ire from Pakistan.

The strategic agreement signed Tuesday by Mr. Karzai and the Indian prime minister, Manmohan Singh, had been in the making for more than five months.
