"Prime Minister Nawaz Sharif is going to take this issue very forcefully at the UN platform," Nafees Zakaria, Foreign Office spokesman, said in his weekly press briefing.
Zakaria said Pakistan has always raised the issue of Jammu and Kashmir at the annual UNGA session and mentioned Sharif's speech at last year's session "where he strongly highlighted the internationally recognized dispute".
He said most UN Security Council members had "already been taken onboard on the continued human rights violations" in Kashmir Valley.
At least 65 people, including children, have been killed in Kashmir Valley battling the worst outbreak of unrest in many years.
The latest round of violence in Kashmir was triggered on July 9, a day after Hizbul commander Burhan Wani, who was hugely popular on social media, was killed.
