The first such event since the deadly clash between the two neighbors in June 2020, Indian and Chinese forces clashed on December 9 in the Tawang region of India’s Arunachal Pradesh state, the Indian army reported on Monday.

On the easternmost point of India, Arunachal Pradesh borders China.

The army reported that “all parties quickly withdrew from the region” and that after the event, its local commander met with his Chinese counterpart to resolve the matter.

An Indian foreign ministry spokesperson did not respond to a request for comment, while a defense spokesperson declined to comment on injuries sustained by Indian or Chinese soldiers during the skirmish.

Neither the Chinese foreign ministry nor its embassy in New Delhi responded to a request seeking comment.

The un-demarcated 3,800 km (2,360 mile) frontier between the Asian giants has stayed largely peaceful since a war in 1962, before the clashes two years ago sent relations nose-diving.

Indian and Chinese soldiers engaged in hand-to-hand warfare in the Galwan Valley in Ladakh in June 2020, which is adjacent to the Tibetan plateau controlled by China.

Twenty Indian soldiers died as a result of the incident, while China also sustained an unspecified number of injuries. In September of this year, the two sides decided to stop occupying the disputed territory along the Himalayan border.

Long-standing regulations have been followed by troops on both sides to refrain from using any firearms along the de facto boundary known as the Line of Actual Control.
