He has said the argument that the UN resolutions on the Kashmir issue have become outdated was not valid and called for early implementation of these resolutions.
The letter was written by Sharif in response to the communication by the fire-brand separatist leader, expressing her satisfaction over the policy of Pakistan government on the Kashmir issue.
"You have expressed faith in the present strategy is a matter of satisfaction for me. Pakistan does not look at Kashmir issue as geographical or boundary dispute. As far as we are concerned, it is the issue concerning the implementation of the formula attached with the division of India in 1947," he has told Indrabi.
He added, "In the past, Pakistan did not lag behind in extending moral, political and diplomatic support to the Kashmiris for their struggle and Insha Allah will continue to stand shoulder to shoulder to the Kashmiris with more determination.
