The move has come after a surprise and unscheduled meeting between Prime Minister Narendra Modi and his counterpart during climate summit in Paris.
NSA Ajit Doval and his Pakistani counterpart Nasir Janjua held talks on host of issues including terrorism, Jammu and Kashmir, peace and security and other issues including tranquility along the LoC, on Sunday, reported ABP news.
"Pursuant to the meeting of the Prime Ministers of India and Pakistan in Paris, the NSAs, accompanied by the Foreign Secretaries, met in Bangkok," said a joint statement issued by both the officials after the meeting.
The Bangkok meeting also paves the way for a visit by External Affairs Minister Sushma Swaraj to Islamabad this week to attend the "Heart of Asia" security conference on Afghanistan.
Swaraj had been invited by Pakistan to attend the conference. The same invitation was extended by Afghanistan too.
