Wang, who is China’s foreign minister, said China must “resolutely respond” to the comments to safeguard the country’s sovereignty and defend its post-war achievements.

“It is shocking that Japan’s current leader has publicly sent the wrong signal of attempting military intervention in the Taiwan issue, said things that shouldn’t have been said, and crossed a red line that should not have been touched,” Wang said in a statement released by the Ministry of Foreign Affairs on Sunday.

The ministry did not specify when Wang made the comments, saying only that they came after his trip to the Central Asian states of Kyrgyzstan, Uzbekistan and Tajikistan. The trip ended on Saturday.

“China must resolutely respond,” he was quoted as saying.

“This is not only to safeguard China’s sovereignty and territorial integrity, but also to defend the post-war achievements won with blood and lives, and to uphold international justice and human conscience.”
