Chinese customs have temporarily halted imports of squid, Pacific saury, beer and other products from Taiwan.

The affected items account for more than 70 percent of Taiwanese food and beverage products registered with China's customs authorities.

Taiwanese authorities said on Thursday that Chinese customs halted seafood imports. The measure was extended to Taiwanese beer and soft drinks the following day.

China blocked imports of about 2,400 Taiwanese products as of Saturday.

Chinese customs authorities implemented a new rule in April 2021 requiring foreign food companies to register information again on their locations and products.

The deadline for Taiwanese companies was set earlier than for others. Taiwanese authorities claimed that the procedures lacked transparency, and that Taiwan was being treated unfairly.

Taiwan's Foreign Minister Joseph Wu tweeted on Saturday that "the PRC is banning some products from Taiwan again, including our beer." He said the move was, "Economic coercion of course," and included a picture of himself holding two cans of Taiwanese beer.

China's Taiwan Affairs Office spokesperson Zhu Fenglian said the affected Taiwanese companies had not properly registered, and that Taiwan should "stop any political manipulation."
