"Pakistan wants peace with India. We have gone the extra mile to achieve this, repeatedly offering a dialogue to address all outstanding issues. But India imposed unacceptable preconditions to engage in a dialogue," Sharif said in a speech at the UN General Assembly.
He added that Pakistan welcomed talks without preconditions.
"Let us be clear. Talks are no favor to Pakistan. Talks are in the interest of both countries. They are essential to resolve our differences especially in Jammu and Kashmir dispute and to avert the danger of any escalation," Sharif added.
Tensions between India and Pakistan entangled in the decades-long dispute over Jammu and Kashmir region have escalated since July after Indian security forces killed Burhan Wani, a renowned separatist commander. On Sunday, a group of militants reportedly crossed from Pakistan into India-administered northern Kashmir territory and attacked the Indian base in Uri, killing 18 servicemen.
In the wake of the attack, Indian Home Minister Rajnath Singh called for isolation of Pakistan from the international community as a state supporting terrorist groups avoiding direct allegations of Pakistani involvement in the Sunday attack. Islamabad claimed to be not implicated in the attack refuting New Delhi's allegations as unsubstantiated.
Last month, spokesman for the Indian Foreign Ministry Vikas Swarup said negotiations between the two countries would take place only if Pakistan agreed on the agenda put forward by New Delhi focusing on anti-terrorism effort ignoring Pakistan's territorial claims.
