China's internal affairs brook no foreign interference: Foreign Ministry

Introducing national security legislation for the Hong Kong Special Administrative Region is purely a matter of China's internal affairs that allow no foreign interference, Foreign Ministry spokesperson Zhao Lijian said Wednesday, in response to US leader's latest remarks on the legislation.

Hong Kong is a special administrative region of China, and the central government is responsible for upholding national security, Zhao told a press briefing.

"To the wrong actions of outside forces in interfering in Hong Kong affairs, we will take necessary countermeasures to hit back," Zhao said.
