"The matter is being dealt with in accordance with the established protocols through institutional mechanisms to deal with situations along the India-China border areas", the military statement added.
China's Defense Ministry said that the Indian unmanned aerial vehicle (UAV) crashed into the Chinese side of the border.
Indian soldiers then alerted Chinese authorities and received assistance in locating the drone.
An Indian drone crossed over the nation's border with China and crashed into in the Sikkim sector, triggering Bejing to protest the intrusion. It is believed that the Indian Army was reconnoitering the Doklam Plateau - a recent standoff zone, when the gadget moved beyond the range of its remote control, causing it to crash in the Chumbi Valley.
"China asks India to immediately stop its activities of using unmanned aircraft near the border, and to work alongside China to maintain the border area's peace and tranquillity", Shuang said, quoted in Reuters. "We strongly express our dissatisfaction and opposition", deputy director of the army's western theatre combat bureau, Zhang Shuili, said in a statement.
China has claimed that an Indian drone "invaded" its airspace before crashing across the Sino-Indian western border. There are no new developments at the face-off site and its vicinity since the August 28 disengagement. Chinese border troops "took a professional and responsible attitude" and carried out identification verification of the device, Zhang said.
There has been no immediate response to the Chinese allegation from India.
The Chinese military's claim came months after India and China were locked in a standoff in the Dokalam sector after the Chinese troops began constructing a road near the Bhutan tri-junction.
Earlier, the Chinese military alleged that an Indian drone has "intruded" into its airspace recently and crashed into the Chinese side of the border and voiced strong dissatisfaction over the incident. The department's jurisdiction includes areas on China's border with India and Bhutan.
Wang's visit to Delhi will be the first visit by a top Chinese official to India after the Dokalam crisis and commencement of the second five-year term for Chinese President Xi Jinping.
