The Security Bureau on Saturday updated its amber outbound travel alert against Japan, saying that there has been an increasing trend of attack incidents against Chinese citizens there since mid-2025.

The government reminded those who wish to go to the country or are already there to exercise caution and pay attention to the latest announcements.

Beijing's embassy in Japan has warned citizens against travelling to the country.

"Recently, Japanese leaders have made blatantly provocative remarks regarding Taiwan, severely damaging the atmosphere for people-to-people exchanges," it said in a WeChat post.

Xinhua News Agency reported that Foreign Ministry spokesman Lin Jian on Friday said China will never compromise or concede on its core interests such as national sovereignty and territorial integrity.

He told a regular news briefing that the root cause of the problem lies in Japanese Prime Minister Sanae Takaichi's "extremely wrongful, dangerous and provocative remarks on Taiwan and her refusal to change course and retract what she had said".

The nation's largest airlines, including Air China, China Southern and China Eastern on Saturday said they will offer refunds for flights on Japan routes or change Japan itineraries free of charge from November 15 until the end of the year. (Additional reporting by AFP)
