Japan: Alliance with US Would Collapse if Taiwan Crisis Ignored

Japanese Prime Minister Sanae Takaiči stated that the country's alliance with the US would be at risk if Japan does not react in the event of an attack on US forces during a potential conflict over Taiwan. Takaiči clarified that this does not involve autonomous military action, but rather a possible joint response to protect citizens and US forces. The statement was made ahead of the upcoming snap elections in Japan on February 8 and has provoked the anger of Beijing, which considers Taiwan an integral part of China. Takaiči had made similar statements in November, emphasizing that Japan should consider all options, including military intervention, if Taiwan were attacked. The Japanese Constitution prohibits direct military action, but allows for the exercise of the right to collective self-defence, i.e. the defence of allies under attack, under certain conditions. Takaiči stressed that Japan will act within the framework of the law and take into account the situation on the ground. The Chinese Foreign Ministry called on Japan to “make sincere self-criticism and correct its mistakes”, as well as to stop its “manoeuvres and reckless actions” on the issue of Taiwan. However, Japan appears to be maintaining a firm stance in protecting its interests and its alliance with the US.
