Around 250 members from Chinese troops crossed into India on the Line of Actual Control at Yangtse, about 25-30 km east of Bum La pass, in western Arunachal Pradesh on June 9, The Hindu reported. However, officials said they returned to the Chinese side in a few of hours.

This is the first time this year that such an incident occurred in the state. However, Indian Army officials said that this happened quite regularly, mostly because of differences in perception of the boundary. On March 8, Chinese troops had entered 6 km into Indian territory near Pangong Lake in Ladakh. Three days later, on March 11, there was a face-off between the Indo-Tibetan Border Police and the Chinese People’s Liberation Army.

Incidentally, the incursion took place a day before Indian began a naval drill with Japan and the United States in the South China Sea. The exercise was part of plans to strengthen military cooperation amid rising tensions in the sea territory. India is currently also making efforts to seek China's support for its membership in the Nuclear Suppliers Group. While the United States has openly backed India's membership, China is the only one to oppose it.
