It was in response to Takaichi’s suggestion earlier this month that Japan could deploy its military forces in the event of a conflict in the Taiwan Strait. It was the first time a sitting Japanese leader had spoken so explicitly about how the country might react in such a situation.
Beijing sees Taiwan as part of China to be reunited with the mainland – by force if necessary.
Most countries, including Japan and its main ally the United States, do not recognise Taiwan as an independent state, but Washington is opposed to any attempt to take the island by force and is committed to supplying it with weapons.
