2020–2021 China–India skirmishes

Beginning on 5 May 2020, Chinese and Indian troops engaged in aggressive melee, face-offs, and skirmishes at locations along the Sino-Indian border, including near the disputed Pangong Lake in Ladakh and the Tibet Autonomous Region, and near the border between Sikkim and the Tibet Autonomous Region. Additional clashes also took place at locations in eastern Ladakh along the Line of Actual Control (LAC).

In late May, Chinese forces objected to Indian road construction in the Galwan river valley. According to Indian sources, melee fighting on 15–16 June 2020 resulted in the deaths of Chinese and Indian soldiers. Media reports stated that soldiers were taken captive on both sides and released in the coming few days while official sources on both sides went on to deny this. On 7 September, for the first time in 45 years, shots were fired along the LAC, with both sides blaming each other for the firing. Indian media also reported that Indian troops fired warning shots at the PLA on 30 August.

Partial disengagement from Galwan, Hot Springs, and Gogra occurred in June–July 2020 while complete disengagement from Pangong Lake north and south bank took place in February 2021. Following disengagement at Gogra in August 2021, Indian analysts pointed out that the LAC has shifted westwards at patrol point 17A (PP 17A).

Amid the standoff, India reinforced the region with approximately 12,000 additional workers, who would assist India's Border Roads Organisation in completing the development of Indian infrastructure along the Sino-Indian border. Experts have postulated that the standoffs are Chinese pre-emptive measures in responding to the Darbuk–Shyok–DBO Road infrastructure project in Ladakh. China has also extensively developed its infrastructure in these disputed border regions and is continuing to do so. The revocation of the special status of Jammu and Kashmir, in August 2019, by the Indian government has also troubled China. However, India and China have both maintained that there are enough bilateral mechanisms to resolve the situation. This includes multiple rounds of colonel, brigadier, and major general rank dialogue, special representatives' meetings, meetings of the 'Working Mechanism for Consultation and Coordination on China-India Border Affairs' (WMCC), and meetings and communication between their respective foreign and defense ministers. On 12 January 2022, the 14th corps-commander-level meeting at Chushul-Moldo Border Personnel Meeting (BPM) point took place. Following the Galwan Valley skirmish on 15 June, some Indian campaigns about boycotting Chinese products were started. Action on the economic front included cancellation and additional scrutiny of certain contracts with Chinese firms, and calls were also made to stop the entry of Chinese companies into strategic markets in India. By November 2020, the Indian government had banned over 200 Chinese apps, including apps owned by Alibaba, Tencent, Baidu, Sina, and Bytedance.
