In a letter to Prime Minister Nawaz Sharif, he thanked Pakistan for supporting Kashmiris for their right of "self-determination".
"The stand taken by Pakistan on the eve of Pak-India NSA-level talks and the way it advocated cause of Kashmir is very encouraging. It has given new strength to the passion of people of Kashmir for independence and helped to highlight the issue at the international level," he wrote.
"We are thankful to you (Sharif), the Pakistan Army and the whole Pakistani nation for continuous support," he said.
India had made it clear that discussions on Kashmir and a meeting with separatists will not be acceptable to it.
