"The civil and military leadership has ruled out any talks with India without Kashmir on the agenda," The Nation reported, a day after Prime Minister Nawaz Sharif chaired a high-level meeting.
The meeting also decided "to fully help Afghan government in checking the movement of militants across the border", it said.
Ahead of the meeting, army chief General Raheel Sharif held a one-on-one meeting with Sharif.
Informed sources were quoted as saying that the two leaders were unanimous that no dialogue should be held with India unless Kashmir issue was part of the agenda.
A foreign ministry official said Pakistan's civil and military leadership was not ready to hold talks without Kashmir being discussed.
"India wants to exclude Kashmir from the agenda to make Kashmir irrelevant. We can't betray Kashmiris. No talks with India can be complete without Kashmir," the official said.
The decision comes after India said it was ready to hold talks with Pakistan but only on the terms that were agreed between prime ministers Nawaz Sharif and Narendra Modi in Ufa in Russia.
