External Affairs Ministry Spokesperson Vikas Swarup on Friday confirmed that India has written a strongly worded letter to Pakistan stating that "not just India but the larger region is aware that Pakistan is the prime perpetrator as far as terrorism is concerned", reported ANI. The letter was sent by India's Foreign Secretary S Jaishankar in response to his Pakistani counterpart Aizaz Chaudhry's August 19 communication in which he had invited Jaishankar to discuss the ongoing unrest in Kashmir.

In his response, Jaishankar said New Delhi has conveyed that the Indian government seeks result-oriented dialogue on the subject, Swarup confirmed. He said Pakistani Foreign Secretary Aizaz Chaudhry has also been told that further discussions will be held as per the Simla Agreement of 1972, Lahore Declaration of 1999 and the Joint Statement of 2004. Swarup further said that the main goal before the two governments is to end cross border terrorism and incitement to violence from Pakistan.

According to the Simla agreement, signed by then Prime Minister Indira Gandhi and Pakistan President Zulfikar Ali Bhutto, both countries decided to avoid conflict and confrontation and work towards peace and cooperation. They agreed to follow a few guidelines to achieve the desired goal of friendly relations between the neighbouring countries. The framework included respect for each other’s territorial integrity and sovereignty, non-interference in each other’s internal affairs, respect for each other's unity, political independence; sovereign equality, and abjuring hostile propaganda. It also underlined the need to uphold the inviolability of the Line of Control in Jammu and Kashmir, according to the Ministry of External Affairs' website.

While signing the Lahore Declaration in 1999, New Delhi and Islamabad agreed to intensify their efforts to resolve all issues, including the issue of Jammu and Kashmir, refrain from intervening or interfering in each other's internal affairs and condemning and combating terrorism, among others.

In 2004, in a joint statement, both sides reiterated their commitment to the principles and purposes of the Charter of the United Nations, and their determination to implement the Simla Agreement in letter and spirit.
