South Korea’s military began two days of drills on Sunday around a tiny island also claimed by Japan, prompting a protest from Tokyo just days after Seoul decided to scrap an intelligence-sharing pact with its neighbour amid worsening relations. The Japanese foreign ministry called the drills unacceptable.
Tensions in the region have spiked amid a worsening political and economic spat between South Korea and Japan, a string of missile launches by North Korea, and increasingly assertive military patrols by China and Russia.
South Korea announced the scrapping of an intelligence-sharing pact with Japan on Thursday, drawing a swift protest from Tokyo and deepening a decades-old dispute over wartime history that has hit trade and undercut security cooperation over North Korea.
Tokyo and Seoul have long been at loggerheads over the sovereignty of the group of islets called Takeshima in Japanese and Dokdo in Korean, which lie about halfway between the East Asian neighbors in the Sea of Japan, also known as the East Sea.
