Tension between Japan and China has escalated over the new Japanese leader's suggestion Tokyo could intervene militarily if Beijing attacks Taiwan.

If you notice any individuals or groups that seem suspicious in any way, do not approach them and leave the area promptly’: embassy.

From China’s point of view, the Japanese Prime Minister’s remarks on Taiwan test a red line - a trigger that sets this dispute apart from past flare-ups, analysts say.

China's Premier Li Qiang has no plans to meet with the Japanese prime minister on the sidelines of the upcoming G20 summit in South Africa, the Chinese foreign ministry said on Monday, as tensions over Taiwan deepen.

Withdrawal follows PM Takaichi’s Taiwan comments, prompting Beijing to issue warnings and cancel exchange events.

The diplomatic row over comments on Taiwan has evolved from a war of words to Beijing advising its citizens against travelling and studying abroad in Japan.
