China says it has agreed with India to peacefully resolve their Himalayan border tensions following the most violent confrontations in decades.

Foreign ministry spokesman Zhao Lijian told reporters at a Wednesday briefing that "both sides agree to resolve this matter through dialogue and consultation and make efforts to ease the situation and safeguard peace and tranquility in the border area."

Zhao repeated Chinese claims that the clashes, in which an Indian officer and 19 soldiers were reportedly killed and many more injured, came after Indian forces "provoked and attacked Chinese personnel, which led to fears (and) physical confrontation between the two sides' border troops and resulted in casualties."

China has not said if any of its troops were injured or killed.

"China has lodged strong protests and stern representations with the Indian side. We once again ask the Indian side to act on our consensus, strictly discipline its front-line troops not to cross the line, not make provocations and not to take unilateral actions that might complicate the situation," Zhao said.

As some commentators clamored for revenge, India's government was silent Wednesday on the fallout from clashes with China's army in a disputed border area in the high Himalayas that the Indian army said claimed 20 soldiers' lives.

An official Communist Party newspaper said the clash occurred because India misjudged the Chinese army’s strength and willingness to respond. The Global Times, which often reflects nationalistic views within the party's leadership, said China did not disclose whether it had casualties in the skirmish to avoid comparisons and prevent further escalation.

Indian security forces said neither side fired any shots in the clash in the Ladakh region late Monday that was the first deadly confrontation on the disputed border between India and China since 1975.

While experts said the two nations were unlikely to head into a war, they also believe easing tensions quickly will be difficult.

Indian Defense Ministry spokesman Col. Aman Anand did not respond immediately to queries on the situation Wednesday or whether talks were planned to defuse the tensions.

"This will likely be a watershed moment in India-China relations and the geopolitics of the Indo-Pacific," said Abraham Denmark, Asia program director at The Wilson Center. "We’ve already seen the deadliest clash on the China-India border in over 50 years, both countries are led by men who have embraced nationalism, and both countries are facing tremendous domestic and international upheaval as a result of COVID-19 and other long-standing problems."

The main questions now are if either side can find a path to de-escalation and whether India's allies such as the United States will help. "It is a highly volatile and dangerous situation between two nationalistic, nuclear powers at a time when American influence has badly diminished," Denmark said.

The editorial published in the Global Times on Wednesday said India’s reaction was largely due to encouragement from the U.S., China’s chief strategic rival which has been steadily building relations with India’s military.

"The arrogance and recklessness of the Indian side is the main reason for the consistent tensions along China-India borders," the editorial said. China "does not and will not create conflicts, but it fears no conflicts either," it said.

China claims about 90,000 square kilometers (35,000 square miles) of territory in India’s northeast, while India says China occupies 38,000 square kilometers (15,000 square miles) of its territory in the Aksai Chin Plateau in the Himalayas, a contiguous part of the Ladakh region.

India unilaterally declared Ladakh a federal territory while separating it from disputed Kashmir in August 2019. China was among the handful of countries to strongly condemn the move, raising it at international forums including the U.N. Security Council.

Thousands of soldiers on both sides have faced off over a month along a remote stretch of the 3,380-kilometer (2,100-mile) Line of Actual Control, the border established following a war between India and China in 1962 that resulted in an uneasy truce.

The Indian Army said three soldiers died initially. The 17 others died after being "critically injured in the line of duty and exposed to subzero temperatures in the high-altitude terrain," it said in a statement Tuesday that did not disclose the nature of the soldiers’ injuries.

The troops fought each other with fists and rocks, Indian security officials said on condition of anonymity because they were not authorized to disclose the information.

After the clash, the two sides "disengaged" from the area where the fighting happened, the Indian Army statement said.

The United Nations urged both sides "to exercise maximum restraint."

"We are concerned about reports of violence and deaths at the Line of Actual Control between India and China," U.N. associate spokesperson Eri Kaneko said. "We take positive note of reports that the two countries have engaged to de-escalate the situation."

Michael Kugelman, a South Asia specialist at the Wilson Center, said that the two countries were unlikely to go to war because they cannot "afford a conflict."

"But let’s be clear: It beggars belief to think that they can magically de-escalate after a deadly exchange with such a higher number of fatalities," he said. "This crisis isn’t ending anytime soon."

Vivek Katju, a retired Indian diplomat, said the deadly violence represented a dramatic departure from the four-decades-old status quo of troops from the two countries staring each other down without any fatalities.

"The political class and the security class as a whole will have to do very serious thinking about the road ahead," he said.

India’s Ministry of External Affairs said in a statement that the incident happened "as a result of an attempt by the Chinese side to unilaterally change the status quo" in the Galwan Valley.

Thousands of soldiers from the two countries, backed by armored trucks and artillery, have been stationed just a few hundred meters (yards) apart for more than a month in the Ladakh region that lies near Tibet. Military and diplomatic meetings have yielded no breakthrough.

Indian authorities have officially maintained near-total silence on the issues related to the confrontation

Indian Prime Minister Narendra Modi had a televised meeting with state officials Tuesday and did not comment on the clash.

The tense standoff started in early May when Indian officials said that Chinese soldiers crossed the boundary in Ladakh at three different points, erecting tents and guard posts and ignoring verbal warnings to leave. That triggered shouting matches, stone-throwing and fistfights, much of it replayed on television news channels and social media.

China has sought to downplay the confrontation while saying the two sides were communicating through both their front-line military units and their respective embassies to resolve issues.

Though skirmishes aren’t new along the frontier, the standoff at Ladakh’s Galwan Valley, where India is building a strategic road connecting the region to an airstrip close to China, has escalated in recent weeks.

The last fatalities along the disputed border was in 1975, when Chinese troops killed four Indian soldiers in an ambush in the Twang region of northeastern India’s Arunachal Pradesh state, said Lt. Gen. D.S. Hooda, a former head of the Indian military’s Northern Command.

"It’s a very complicated and serious situation, and it will take real, hard negotiating skills to resolve this," Hooda said.
