After an Indian army officer and two soldiers were killed at the Galwan Valley in Ladakh, China "calls on India to not take unilateral actions or stir up trouble", reported news agency Reuters.
The comment was made by China's Foreign Ministry.
The army in a statement a short while ago said the Indian army personnel were killed in "a violent face-off" last night and that military representatives of both countries are meeting now at the location to defuse tensions. The statement spoke of "casualties on both sides."
Beijing accused Indian troops of crossing into its territory.
Army sources said the three Indian personnel killed were not shot.
The huge escalation of hostilities comes after high-level talks between military officers of both sides. There were reports last week that both armies had thinned out forces; however, experts warned that soldiers, tanks and other armoured carriers remained heavily deployed in the high-altitude region. Indian sources have also said that China has advanced into new territory at the strategically vital Pangong Lake.
