THE clash between the Indian and Chinese troops in the Galwan valley area along the Line of Actual Control (LAC) in the Ladakh sector marks a new flashpoint of friction between the two neighbours. It is the first major case of border skirmish between India and China since 1975, and given the growing scale of casualties on both sides it is the worst since the Nathu La and Cho La clashes on September 11-14 and October 1, 1967, along the Sikkim border.
