"If there is a roadmap, then, yes, we will talk," PM Imran told Reuters at his official residence in Islamabad.

"Even if they give us a roadmap, that these are the steps that we will take to basically undo what they did, which is illegal, against international law and United Nations resolutions... then that is acceptable," Khan said.

Pakistan in March deferred a decision by its top economic decision-making body to restart trade with India until Delhi reviewed its moves in Kashmir.

He said India had crossed a "red line" by revoking the autonomy of its part of Kashmir. "They have to come back for us to resume dialogue," Imran Khan said, adding, "at the moment there is no response from India".
