SRINAGAR, India (AP) — The Indian army said it apprehended a Chinese soldier Monday in the remote Ladakh region, where the two countries are locked in a monthslong military standoff along their disputed mountain border.

The soldier, Cpl. Wang Ya Long from China’s People’s Liberation Army, was apprehended inside Indian-controlled Ladakh’s Demchok area and was to be released soon, the army said in a statement.

It said the soldier “had strayed” across the de facto border along the eastern section of what’s known as the Line of Actual Control, a loose demarcation separating Indian- and Chinese-controlled areas.

“As per established protocols, he will be returned back to Chinese officials at the Chushul–Moldo meeting point after completion of formalities,” the statement said.

China did not immediately comment on the soldier’s apprehension.

The high-altitude standoff between the Asian giants began in early May with a fierce brawl, and exploded into hand-to-hand combat with clubs, stones and fists on June 15 that left 20 Indian soldiers dead. China is believed to also have had casualties, but has not given any details.

China detained at least 10 Indian soldiers, including four officers, following the deadly brawl. They were returned three days later after intense military and diplomatic negotiations.

The Indian army statement Monday said the Indian side had received an inquiry from China’s military “about the whereabouts of the missing soldier.”

The soldier “has been provided medical assistance including oxygen, food and warm clothes to protect him from the vagaries of extreme altitude and harsh climatic conditions,” the statement said.

India and China have each stationed tens of thousands of soldiers backed by artillery, tanks and fighter jets and are bracing for a harsh winter in the cold-desert region, where temperatures can fall to minus 50 degrees Celsius (minus 58 Fahrenheit).

The nuclear-armed rivals have accused each other of crossing into rival territory and of firing shots for the first time in 45 years.

The sides have held several rounds of talks by military, diplomatic and political officials, including negotiations between their foreign ministers and defense ministers in Moscow last month. Although the standoff has persisted, the talks seem to have calmed the situation along the border, with no new military aggression reported for over a month now.

The fiercely contested Line of Actual Control separates Chinese-held and Indian-held territories from Ladakh in the west to India’s eastern state of Arunachal Pradesh, which China claims in its entirety. It is broken in parts where the Himalayan nations of Nepal and Bhutan border China.

India claims the Chinese-controlled Aksai Chin plateau as part of the Ladakh region.

According to India, the control line is 3,488 kilometers (2,167 miles) long, while China says it is considerably shorter. The line divides the areas of physical control rather than territorial claims.

Relations between the two countries have often been strained, partly due to their undemarcated border. They fought a border war in 1962 that spilled into Ladakh and ended in an uneasy truce. Since then, troops have guarded the undefined border and occasionally brawled. They have agreed not to attack each other with firearms.

India unilaterally declared Ladakh a federal territory and separated it from disputed Kashmir in August 2019, ending Indian-administered Kashmir’s semi-autonomous status. It also vowed to take back the Aksai Chin plateau.

China was among the first countries to strongly condemn the move, raising it at international forums including the U.N. Security Council.
