On 10 May 2020, Chinese and Indian troops clashed in Nathu La, Sikkim, leaving 11 soldiers injured. Following the skirmishes in Sikkim, tensions between the two countries grew in Ladakh with a buildup of troops at multiple locations. There were reportedly 20 Indian and 43 PLA casualties on the night of 15/16 June. China reinforced troops near the Indian border with Tibet, Chinese state media reported. Bilateral agreements between India and China prevent the use of guns along the line of actual control; however these skirmishes saw the first shots, warning shots, being fired in decades.
