Fresh India-China Border Face-Offs Raise Questions Over Arunachal Pradesh Frontier

India's border police chief has confirmed that Indian and Chinese troops have confronted each other at several locations along the de facto border in the northeastern state of Arunachal Pradesh, and that the standoffs are continuing.

Shatrujeet Kapur, director general of the Indo-Tibetan Border Police, told reporters last month that a situation had arisen in recent days in which face-offs with Chinese troops occurred at various locations in Arunachal and were still under way. He warned that countering China by conventional means could be difficult because its People's Liberation Army and Border Defense Regiment have advanced significantly in investment and modernization.

The disputed frontier runs through a remote Himalayan region along the Line of Actual Control, or LAC, where clashes have repeatedly triggered security crises between the world's two most populous nations. Relations remain strained by the deadly violence of 2020, when a June clash in the Galwan River valley in eastern Ladakh killed 20 Indian soldiers and four Chinese troops, according to Indian sources, with China later confirming four of its soldiers died.

Arunachal Pradesh Chief Minister Pema Khandu acknowledged the border transgressions but downplayed them, saying such incidents were not new and that the situation along the border was normal. He noted that the boundary is not properly demarcated and that China does not recognize the McMahon Line, drawn by the British Empire in 1914, which separates Arunachal Pradesh from Tibet. It remains unclear whether the latest confrontations involved physical violence.

The opposition Congress party accused Prime Minister Narendra Modi's ruling BJP of rationalizing Chinese actions rather than asserting India's position, with Congress general secretary Jairam Ramesh writing on X that there had been a deafening silence from the prime minister and his establishment. External Affairs Ministry spokesperson Randhir Jaiswal attributed the incidents to Chinese forces diverging from established patrolling patterns, while Chinese Foreign Ministry spokesperson Guo Jiakun rejected the allegations, saying Chinese troops were conducting normal patrols and strictly observing bilateral agreements.

Gautam Bambawale, a former Indian ambassador to China, said the reason for recurring face-offs is simple: there is no agreed line between the two countries. India says the de facto border stretches 3,488 kilometers, though China claims it is shorter, and 25 rounds of talks between the two countries' Special Representatives since 2003 have failed to produce a boundary settlement. The dispute is especially sensitive in Arunachal Pradesh, which China claims as part of southern Tibet.

Aravind Yelery, a China expert at Jawaharlal Nehru University, said friction is built into an arrangement in which both sides patrol a contested LAC. He said what is new is China's intensified focus on the eastern sector since announcing the 60,000-megawatt Medog hydropower project in Tibet, which has brought infrastructure, troops, engineers and machinery into the area. He described the LAC as not a thin line but a deep zone of overlapping claims, and said a wide gap separates leaders' promises from the disengagement and mutual restraint needed to prevent a repeat of 2020.

Ashok Kantha, another former Indian ambassador to China, said Chinese transgressions in the eastern sector were not new, but that deeper intrusions, a presence in new areas or an expansion of existing positions would be a serious development and a complete violation of border agreements signed in 1993, 1996, 2005, 2012 and 2013. The Indian government has not publicly disclosed the locations or circumstances of the latest encounters.

The incidents come as India and China attempt to stabilize ties, restoring some direct flights and easing travel and economic restrictions following meetings between Modi and Xi Jinping at the BRICS summit in Kazan in October 2024, the SCO summit in Tianjin in August 2025 and the BRICS summit in New Delhi this year. Alka Acharya, director of the Institute of Chinese Studies in New Delhi, cautioned that any assessment of the latest incidents would be conjecture without definitive evidence, adding that the unresolved dispute will continue to sustain distrust and constrain the broader relationship.
