After the humiliating Chinese Aggression in 1962 there were a large number of incursions culmination into violent attacks by PLA at Nathula and Chola in Sikkim in September and October 1967. Indian Army’s aggressive retaliation in 1967, which was supported by then Prime Minister Indira Gandhi, at least broke the 1962 jinx and may also have resulted in Chinese stepping down after build-up of tension and stand-off at Sumdorong Chu Valley in Arunachal Pradesh in 1984 and 1987.
It has been 50 years since the Chinese Aggression of October 1962, two years after India gave asylum to the Dalai Lama, considered by Beijing as a separatist and a veritable red rag to a bull. Much water has flowed down the Tsangpo-Brahmaputra river in North-east over these years. Trade has increased from $3 billion a decade ago to an annual $75.5 billion today, still old tensions remain. On the anniversary of the Chinese Aggression all three service chiefs paid homage at Amar Jawan war memorial.
