Confirming a Chinese military claim made earlier today, the Ministry of Defence (MoD) has said that an Indian Unmanned Aerial Vehicle (UAV) lost control on a regular training mission and crossed the Line of Actual Control (LAC) with China in Sikkim.
After the weeks of confrontation on the wind-swept Doklam plateau this year, the two sides agreed to an "expeditious disengagement" of troops about a week before Chinese President Xi Jinping and Indian Prime Minister Narendra Modi met in an effort to mend ties at a summit in China in September. The exact cause of the incident is under investigation.
Responding to China's statement that over a drone crashing into Chinese territory, the Ministry of Defence on Thursday issued a statement where they admitted to the incident taking place.
The matter is being dealt with in accordance with established protocols and through institutional mechanisms that exist for similar situations in the India- China border areas, the statement added.
"India's move has infringed upon China's territorial sovereignty and we are strongly dissatisfied with and opposed to this", he said.
Chinese border troops "took a professional and responsible attitude" and carried out identification verification of the device, said Mr Zhang. "We will fulfill our mission and responsibility and defend China's national sovereignty and security resolutely".
Chinese military's western theatre command jurisdiction covers nearly all of the 3488-km LAC, including Tibet's border region with India and the Ladakh region.
China's accusation comes months after the two countries ended one of their worst border standoffs in decades in the disputed Doklam region near Indian state Sikkim.
The standoff began in mid-June after Chinese troops started building a road on the remote Doka La plateau.
Indian and Chinese troops were in a face-to-face situation near the Sikkim sector of the worldwide border after the Chinese People's Liberation Army tried to build a road in Doklam in mid-June.
