The headline pertains to China's military activities involving High City, at the expense of the usual non-action of Japan. Japan is seen to hold its ground in line with its diplomatic strategy even as the Chinese military makes moves in High City. There's no specified action plan from Japan's side yet, with Tokyo seeming to prefer to observe and not more directly engage for now.

Japan has often taken a secure but passive stance when it comes to Chinese military actions, leaning on diplomatic measures over direct confrontation. This response is guided by Japan's self-defense law and is symbolic of the nation's pacifist policies. The public generally supports this approach, valuing peace and stability.

This contrasts with the US or EU's approach which might involve more direct diplomatic warnings or sanctions in response to Chinese military actions. EU and US are more confrontational and may actively call China out on alleged aggressive activities.
