Her recent comments do not represent a new commitment for Japan to defend Taiwan – or a departure from previous policy.

Foreign ministry’s Asian affairs chief Liu Jinsong ‘very unsatisfied’ after talks with Japan counterpart, Chinese media reports.

TOKYO -- China tensions triggered by Japanese Prime Minister Sanae Takaichi's recent comment on a potential crisis in Taiwan remain high, but two related issues -- Japan acting alongside U.S. forces and its exercise of collective self-defense rights in defending the island -- need to be considered separately, former officials say.

Relations between the two neighbours have soured recently after Takaichi became the first sitting Japanese leader in decades to publicly link a Taiwan Strait crisis with the possible deployment of Japanese troops.

The Japanese public is divided over exercising collective self-defense against a Chinese attack on Taiwan. A recent poll shows mixed opinions, while Prime Minister Sanae Takaichi aims to boost defense spending.

The postponement comes barely two weeks after remarks about Taiwan by Japanese Prime Minister Sanae Takaichi sparked a heated response from China and kicked off the most serious diplomatic clash between the two East Asian powers in years.
