The diplomatic rift between Beijing and Tokyo is also a test of Washington’s appetite for engagement with the region

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

Tensions between the Asian neighbours flared up after new Japanese Prime Minister Sanae Takaichi said this month that a Chinese attack on Taiwan threatening Japan's survival could trigger a military response.
