Former External Affairs Minister K Natwar Singh on Tuesday regretted that India has not yet comprehensively analysed the reasons behind the 1962 war with China, saying such an exercise was "really necessary."
Speaking at a discussion on his recent book 'My China Years -- 1956-88, he touched upon various phases of Sino-India relationship in the last 60 years and felt things would have been different had Rajiv Gandhi won the 1989 elections.
"Why 1962 happened. No serious analysis of it took place on our side," Singh said indirectly criticising Government's secretive policy in revealing details of the war.
About the war with China, he said "Mao-tse Tung decided to teach India a lesson after they felt that we were encroaching on their land."
India missed an opportunity to resolve the issues with China in 1960 as the country "did not understand the power game", the former minister said, without elaborating on his observation.
On the border dispute, he said Tawang did not figure in the map of India in 1953.
