China ramps pressure after Japan transit
- China publicly criticized a Japanese destroyer’s transit of the Taiwan Strait and signaled displeasure to Tokyo. - Chinese navy vessels subsequently sailed between islands off southwestern Kyushu and near Okinawa in a likely tit‑for‑tat move. - The pattern underlines Japan becoming more prominent in Taiwan‑related security drills and regional signaling (asia.nikkei.com) (freemalaysiatoday.com).
China escalated its dispute with Japan days after a Japanese destroyer crossed the Taiwan Strait, sending naval ships through waters near Okinawa and southwestern Kyushu. (reuters.com) China’s foreign ministry said on April 17 that a Japan Maritime Self-Defense Force vessel had entered the strait and called it “a deliberate provocation.” China’s defense ministry said it lodged a “strong protest” over the destroyer JS Ikazuchi. (reuters.com) (english.scio.gov.cn) Japanese media reported the Ikazuchi made the passage on April 17, the first transit by a Maritime Self-Defense Force ship in about 10 months. The ship was heading south as Tokyo deepened coordination with partners around Taiwan and the northern Philippines. (japannews.yomiuri.co.jp) (asia.nikkei.com) On April 22, Reuters reported that Chinese naval vessels, including a destroyer, passed between islands administered by Okinawa prefecture after earlier moving out through the Yokoate Waterway on April 20. Japan’s Defense Ministry had already disclosed the Sunday transit between Amami Oshima and Yokoatejima in Kagoshima prefecture. (reuters.com) (japannews.yomiuri.co.jp) The Taiwan Strait is the narrow waterway between Taiwan and mainland China, and foreign navy passages there have become a test of rival legal claims. Beijing says the strait is not international waters, while the United States and its allies continue to treat transits as lawful. (reuters.com 1) (reuters.com 2) Japan has moved closer to the Taiwan question since Prime Minister Sanae Takaichi said in November 2025 that a Chinese attack on Taiwan could trigger a Japanese military response. Chinese state and party-linked outlets have since tied Japanese moves near Taiwan to that remark. (reuters.com) (japannews.yomiuri.co.jp) That shift has shown up in drills as well. Asahi reported in September 2025 that Japan and the United States launched Resolute Dragon 2025 with 19,000 personnel across eight prefectures, centered on defending remote islands in Japan’s southwest. (asahi.com) China says its ship movements near Japan were routine training and a return transit after “testing far-seas capabilities.” Japanese officials have not publicly framed the latest passage as illegal, but Tokyo has steadily expanded surveillance and public disclosure of Chinese naval movements around the Ryukyu island chain. (reuters.com) (mod.go.jp) The immediate standoff is about one destroyer and one waterway, but the map is wider: Taiwan, Okinawa, the southern Japanese islands and the approaches to the western Pacific are now part of the same military signaling contest.
