India and China have been locked in a border dispute since April when rival soldiers were engaged in skirmishes at several points on their mountain border.
The two nuclear-armed Asian neighbours share a 3,500-kilometre（(2,100-mile） unmarked border through the Himalayas, but an uneasy peace has held since the two countries signed a truce following a war in 1962.
On June 15, the border peace was broken following deadly clashes between Indian and Chinese soldiers in Galwan Valley in India’s Ladakh region. At least 20 Indian soldiers died in pitched hand-to-hand combat involving clubs and rocks.
Since then, thousands of soldiers have been deployed on both sides of the de facto border, known as the Line of Actual Control（LAC）, with experts concerned tensions might lead to an unintentional war.
An argument or disagreement, especially an official one.
China and India's border dispute turned deadly for the first time in more than four decades.
