China lodged stern representations with Japan after Japanese Prime Minister Yoshihide Suga referred to the Taiwan region as a country, Chinese Foreign Ministry spokesperson Wang Wenbin said on Thursday.
Suga's remarks severely breached Japan's promise on not regarding Taiwan as a country, Wang told a regular press briefing.
Wang called on the Japanese side to make a clear clarification and make sure this kind of incident never happens again.
He urged Japan to honor its promises, be cautious with its words and actions and not damage China's sovereignty in any way.
