Japan has announced a plan to deploy surface-to-air missile systems on Yonaguni Island by 2031, constituting a strategic response to Beijing's growing assertiveness. This decision coincides with China imposing export restrictions on 20 Japanese defense sector firms. Simultaneously, Beijing is rejecting American accusations of secret nuclear tests, accusing Washington of manipulations aimed at concealing its own arms buildup.

Militarization of Yonaguni Island

Japan has officially set the deployment date for surface-to-air missiles 110 km from Taiwan for the fiscal year 2030.

Chinese economic sanctions

Beijing has blocked the export of 'dual-use' goods to 20 Japanese firms from the defense and space sectors.

Dispute over nuclear tests

China has rejected U.S. accusations regarding alleged secret atomic tests at the Lop Nur test site.

Financial markets reaction

Shares of Japanese defense conglomerates recorded declines in reaction to Chinese export restrictions, while the yen remained under pressure from broad market factors.

Japanese Defense Minister Shinjiro Koizumi confirmed that a missile unit will be stationed on Yonaguni Island by March 2031. This decision aligns with Tokyo's new defense strategy, championed by Prime Minister Sanae Takaichi. Beijing reacted to these plans with accusations of "remilitarization" and promptly introduced a ban on the export of dual-use products to key Japanese enterprises, such as Mitsubishi Heavy Industries. The sanctions are extraterritorial in nature, meaning they impact the global supply chains of corporations cooperating with Tokyo. The situation is further exacerbated by reports from the nuclear security sphere. The United States has again raised accusations against China of conducting a secret low-yield nuclear explosion at the Lop Nur test site in 2020, which, according to Washington, violates international standards. Chinese Foreign Ministry spokesperson Mao Ning firmly rejected these claims, calling them baseless speculation. In the background of these events, Russia issued a warning about the risk of a direct clash between nuclear powers, which is a reaction to alleged plans by Western states to supply nuclear components to Ukraine. Regional tensions have translated to financial markets, causing a weakening of the yen and declines in the shares of Japanese defense companies. Japan-China relations have remained tense since the end of World War II, and the dispute over the Senkaku Islands and the status of Taiwan regularly leads to diplomatic crises between the Asian powers. „The accusations by the United States are based on speculation and vague insinuations.” — Mao Ning 110 km — separates the Japanese island of Yonaguni from Taiwan Japan's domestic politics are also stirring emotions, as Prime Minister Takaichi had to fend off accusations regarding distributing gift catalogs to parliamentarians of her party, which the opposition deemed controversial in the context of political party funding. Nevertheless, the head of government is focused on passing a budget to finance ambitious plans for military modernization and investments in economic security in cooperation with the USA.
