Indian media reported that a Chinese soldier was apprehended by Indian troops near the south bank of Pangong Tso Lake in Ladakh on Friday.
Sources close to the matter told the Global Times that the soldier lost his way and was captured by the Indian side. China and India are negotiating the situation.
There were previously occasions when soldiers from both sides lost their way and crossed the border.
In October, a PLA soldier went missing while helping a herdsman find his yak along the China-India border. After China urged India to help in the search, India later notified China that a missing person from China had been found and would be returned to China after a medical exam.
