The 1967 Sino-Indian skirmish, also known as the Cho La incident, was a military conflict between Indian troops and members of the Chinese People's Liberation Army who, on 1 October 1967, invaded Sikkim, which was then a protectorate of India. On 10 October, both sides clashed again. Defence minister Sardar Swaran Singh assured the Indian people that the government was taking care of developments along the border. Indian losses were 88 killed, and 163 wounded, while Chinese casualties were 300 killed and 450 wounded in Nathula, and 40 in Chola. The Chinese Army left Sikkim after this defeat.
