Incursion by drone sparks ire in Beijing

China expressed on Thursday "strong dissatisfaction and opposition" to India after an Indian drone entered and crashed in Chinese territory, an incident that experts said may upset the recent positive development of Sino-Indian relations.

China's Defense Ministry said in a release that the incident "undermined China's territorial sovereignty".

Chinese border troops examined and identified the drone, the ministry said, adding the Chinese military will "adamantly fulfill its duty and protect the security of national sovereignty".
