India and China relations have entered a critical new phase following fresh conflict along their disputed Himalayan border, after multiple rounds of high-level military talks failed to end the monthslong standoff.

The Defense Ministry in New Delhi said on Monday its soldiers were able to stop a push by Chinese troops to claim more ground late Saturday in violation of existing agreements.

Beijing denied its troops had strayed into Indian territory and said it was in close communication with New Delhi, Chinese Foreign Ministry spokesman Zhao Lijian said at a daily briefing in Beijing on Monday. "Chinese border troops always strictly abide by the Line of Actual Control,” Zhao said.
