The Chinese military has claimed that an Indian drone invaded China's airspace before crashing near a disputed border region.
The state news agency Xinhua on Thursday presented a report in which Zhang Shuili, deputy director of the combat department of the joint staff department of the West Theater Command, said: "India's measure has infringed the territorial sovereignty of China, and we are very dissatisfied and opposed to this. "
Claims do not include details about the timing or specific location of the incident. The jurisdiction of the department includes areas on the border of China with India and Bhutan.
Shuili added: "We will fulfill our mission and responsibility and we will defend the country sovereignty and security resolutely." He said the Indian unmanned aerial vehicle (UAV) "interfered in China's airspace and crashed recently, and China's border troops have made the identification and verification of the vehicle."
The Indian Army offered more information about the incident, saying that the drone was on a training mission in Indian territory, but crossed into Chinese territory due to a technical fault whose exact cause is under investigation.

The state of Sikkim, in northeastern India, borders China through Tibet, as well as Bhutan and Nepal.
Indian soldiers alerted the Chinese authorities and received help to locate the unmanned aircraft.
"The matter is being dealt with in accordance with the" The military statement added.
China formally complained about the incident with Indian diplomats, said Chinese Foreign Ministry spokesman Geng Shuang at a regular press conference.
] "China calls on India to immediately stop its drone activity near the border and work with China to maintain the peace and tranquility of the border area," Shuang was quoted as saying in Reuters.
Tensions between the two Asian countries increased earlier this year around a Himalayan plateau known as Doklam in India and Donglang in China.
The confrontation began in June when the clothes obstructed the construction of a Chinese road on the plateau. China claims the area as sovereign territory in the light of a 1890 border agreement signed between Britain and the Qing Dynasty, but is also the subject of an agreement with Bhutan in which the two countries agreed to maintain the status quo throughout the border not marked. India said it acted in consultation with the Bhutanese government when the construction of the highway violated the status quo.
After weeks of growing tensions, India and China agreed to a "quick withdrawal" of troops to resolve the confrontation in late August, before a meeting between the leaders of the countries at the BRICS Summit held in early China of September.
