China said on Tuesday it opposed the United States interfering in its internal affairs, in response to a report that Washington will warn U.S. companies of risks of operating in Hong Kong.

Hong Kong basic law and relevant laws clearly protect the interests of foreign investors, foreign ministry spokesman Zhao Lijian told a regular briefing.

The Financial Times reported on Tuesday that the U.S. government will this week warn companies of increasing risks of operating in Hong Kong and also update a previously issued warning on Xinjiang.
