China has expressed concern over Japan's decision to send members of its Self-Defense Forces to NATO's Security Assistance and Training for Ukraine (NSATU).

Chinese Foreign Ministry spokesperson Lin Jian said this at a briefing on Monday, according to an Ukrinform correspondent.

"China is concerned about the actions of the Japanese side, which is actively promoting remilitarization and expanding the geographical scope of its military activities. We call on the international community to remain highly vigilant regarding manifestations of new Japanese militarism," Lin said, commenting on reports that Tokyo had decided to dispatch four officers to a military base in Germany to observe NATO-led programs supporting Ukraine.

In his opinion, such steps could lead to the involvement of Japanese military personnel in actual combat operations, which, he said, contradicts Japan's pacifist commitments.
