evidence: In addition to Kokang and Wa State, two places that often appear in the news, Jiangxinpo, Myanmar, was once Chinese territory. [...] As for Jiangxinpo, the actual situation is that China and Myanmar have no control over the area. [...] Under heavy pressure, the Yunnan authorities of the Republic of China submitted a note of protest to the British Consul General in Yunnan, saying: "The Chajiangxinpo area still belongs to Chinese territory. The boundary between Yunnan and Myanmar has not yet been determined and the negotiations between Myanmar and Myanmar have not been resolved. The government sent troops to control the Jiangxinpo area again, and captured 11 mountain officials, which completely violated the purpose of Sino-British friendship. The approval letter was preceded by a corresponding note to the Consul General for checking, and forwarded to the Burmese government, and all the private piles sent to the north of Jiangxinpo were promptly dispatched. Withdraw and wait for the inspection by senior officials from China and Britain in the future, to Renmuyi."
