The original Track II initiative, Neemrana Dialogue, received a fresh start with the visit, diplomatic sources here said.
The Indian side was led by former foreign ministry secretary Vivek Katju and included well-known educationist J S Rajput and other experts, while Pakistan side was led by former foreign secretary Inamul Haque.
The interactions between the two sides took place between April 28 to 30 in Islamabad, sources said.
"The two sides discussed all aspects of bilateral relations and agreed that all issues between the two countries should be resolved through talks," according to a source.
The Pakistani side also included former governor State Bank of Pakistan Ishart Hussian, whose name has been circulating in the media as one of candidates to become Pakistan's caretaker prime minister during general election expected to be held in July.
The Track II interaction was kept under tight wraps and nothing had been shared officially about it by the organisers.
Neemrana Dialogue was launched in early 1990s and included influential former diplomats, military veterans and academics, who were having unofficial backing from the foreign ministries of the two countries.
The India-Pakistan ties nose-dived in recent years with no bilateral talks taking place.
The ties between the two countries had strained after the terror attacks by Pakistan-based groups in 2016. The sentencing of Kulbhushan Jadhav further deteriorated bilateral ties.
