Meanwhile, the new Japanese PM is rolling up her sleeves...
How the Japan PM's Taiwan remarks provoked the fury of China
Over the past few days, China and Japan have been locked in an escalating war of words.
It all started when Japan's new Prime Minister, Sanae Takaichi, suggested that if China attacked Taiwan then Japan could respond with its own self-defence force.
Since then, foreign ministries on both sides have lodged serious protests with the other, with Beijing summoning the Japanese ambassador. A Chinese diplomat also made what some interpreted as a threat to behead Takaichi.
The spat touches on the historical animosity between China and Japan, as well as longstanding "strategic ambiguity" on the sovereignty of Taiwan.
Sanae Takaichi drew fire after suggesting Tokyo could take military action if Beijing attacked Taiwan.
