Dozens of Indian and Chinese soldiers were injured in a cross-border clash involving fistfights and stone-throwing at a remote but strategically important mountain pass near Tibet, the Indian Army said Sunday according to the Straits Times and BBC.
There have been long-running border tensions between the nuclear-armed neighbours, with a bitter war fought over India's north-eastern-most state of Arunachal Pradesh in 1962.
The two countries have competing claims over their shared 3,400 kilometre (2,100 mile) border. Sometimes stand-offs involve chest-bumping, pushing and shoving, and throwing stones at each other, BBC South Asia Editor Anbarasan Ethirajan reports.
The latest tense face-off took place near the Naku La sector in Sikkim, more than 5,000 meters (16,400ft) above sea level in the Himalayas.
"Aggressive behaviour by the two sides resulted in minor injuries to troops. It was stone-throwing and arguments that ended in a fistfight," Indian Army Eastern Command spokesman Mandeep Hooda told AFP.
The "stand-off" on Saturday at Naku La sector near the 4,572m Nathu La crossing in the north-eastern state of Sikkim - which borders Bhutan, Nepal and China - was later resolved after "dialogue and interaction" at a local level, Hooda said.
"Temporary and short duration face-offs between border-guarding troops do occur as boundaries are not resolved," he added.
The violent clash is the first between the two countries since 2017, when there was a brawl between Chinese and Indian soldiers near the northwest Indian region of Ladakh. Though both countries send out patrols that often engage in physical stand-offs, no bullet has been fired over the border in the last four decades.
In the same year, there was a high-altitude standoff in Bhutan's Doklam region after the Indian army sent troops to stop China from constructing a road there.
China still claims about 90,000 sq km of territory under New Delhi's control.
