India suffered a humiliating defeat in the 1962 war.
The Chinese side was "unusually warm" during the third round of talks and wanted a formal border management agreement along the more than 4,000-km-long Line of Actual Control (LAC).
The Chinese side, the sources said, is expected to soon send proposals in this regard which would also suggest the two sides to agree on their troops not firing at each other under any circumstances.
