Defence secretaries from both countries held two days of closed-door talks in New Delhi on how to reach an agreement on withdrawing troops from the mountainous no-man's land above the Siachen glacier and defining the official border.

It was the 12th round of inconclusive talks on Siachen, considered one of the less difficult disputes to resolve between India and Pakistan.

India and Pakistan agreed to meet in Islamabad for the talks.

"Both sides agreed to continue the discussions in a meaningful and result-oriented manner. They agreed to meet again on a mutually-convenient date in Islamabad," a joint statement by India and Pakistan said.
