• This suspension affects a significant portion of Japan's seafood exports, with China accounting for over one-fifth of those sales.

China has informed Japan that it will suspend all imports of Japanese seafood, escalating tensions that have been amplified by political statements made by Japan's Prime Minister Sanae Takaichi regarding Taiwan. The suspension comes less than five months after China had lifted a nearly two-year ban put in place over the release of treated wastewater from the Fukushima nuclear plant in 2023, a decision that was welcomed in Japan as it sought to restore trade relations, according to thejakartapost and scmp.

The Japanese Prime Minister's comments suggesting Japan could intervene militarily if Taiwan were attacked provoked a strong backlash from Beijing, which demands retraction of the statements. Takaichi's remarks were seen as fundamentally damaging to the political foundation of China-Japan relations, leading to further deterioration in diplomatic dialogue, reports channelnewsasia and aljazeera.

Beijing indicated that the seafood ban is motivated by the need to monitor the discharge of treated water from the Fukushima plant, emphasizing precautionary measures. Reports suggest that this ban significantly impacts Japan's seafood market, potentially affecting the livelihoods of Japanese exporters who had just begun to regain access to the Chinese market, which accounted for a substantial portion of Japan's seafood exports, according to reuters and indiatimes.

As the diplomatic row intensifies, Japan has issued warnings to its citizens residing in China to observe increased caution, particularly in public spaces. Likewise, China has instructed its nationals to avoid travelling to Japan, further straining people-to-people connections at a time when both nations had sought to improve bilateral relations through cultural exchanges and tourism, as highlighted by indiatimes and abcnews.
