BANGKOK (AP) — China announced Friday that it will impose a 34% tax on all U.S. imports next week, part of a flurry of retaliatory measures to U.S. President Donald Trump’s new tariffs that delivered the strongest response yet from Beijing to the American leader's trade war. The tariffs taking effect Thursday match the rate that Trump this week ordered imposed on Chinese products flowing into the United States. In February and March, Trump slapped two rounds of 10% tariffs on Chinese goods, citing allegations of Beijing's role in the fentanyl crisis. The U.S. stock market plunged Friday following China’s retaliatory moves. They include more export controls on rare earth minerals, which are critical for various technologies, and a lawsuit at the World Trade Organization over what Trump has dubbed reciprocal tariffs. China also suspended imports of sorghum, poultry and bonemeal from six U.S. companies, added 27 firms to lists of companies facing trade restrictions, and launched an anti-monopoly investigation into DuPont China Group Co., a subsidiary of the multinational chemical giant. Trump posted Friday on Truth Social: “CHINA PLAYED IT WRONG, THEY PANICKED - THE ONE THING THEY CANNOT AFFORD TO DO.” Yet he also indicated he could still negotiate with China on the sale of TikTok even after Beijing pressed pause on a deal following the new tariffs. On Friday, he extended the deadline for the social media app to divest from its Chinese parent company, per a federal law, for another 75 days. “We hope to continue working in Good Faith with China, who I understand are not very happy about our Reciprocal Tariffs,” Trump posted on his social media site. “We look forward to working with TikTok and China to close the Deal.” China's response to tariffs grows tougher Beijing’s response is “notably less restrained” than during the recent two rounds of 10% tariffs on Chinese goods, and that “likely reflects the Chinese leadership’s diminished hopes for a trade deal with the U.S., at least in the short term,” wrote Gabriel Wildau, managing director of the consultancy Teneo. He said Beijing's tough response could trigger further escalation, with no sign that Chinese President Xi Jinping and Trump might meet soon or get on the phone to ease the tensions. If China’s previous responses were scalpels, this time it drew a sword, said Craig Singleton, senior China fellow at the Foundation for Defense of Democracies, a Washington-based think tank. “China’s new tariffs stop short of full-blown trade war, but they mark a clear escalation — matching Trump blow-for-blow and signaling that Xi Jinping won’t sit back under pressure,” Singleton said. But the escalation also is squeezing out space for diplomacy, he warned. “The longer this drags, the harder it becomes for either side to deescalate without losing face,” Singleton said. What China's retaliatory measures look like In Beijing, the Commerce Ministry said it would impose more export controls on rare earths — materials used in high-tech products such as computer chips and electric vehicle batteries. Included in the list was samarium and its compounds, which are used in aerospace manufacturing and the defense sector. Another element called gadolinium is used in MRI scans. China's customs administration said it had suspended imports from two U.S. poultry businesses after officials detected furazolidone, a drug banned in China, in shipments from those companies. It said it found high levels of mold in the sorghum and found salmonella in the bonemeal feeds from four other U.S. companies. The Chinese government said it also added 16 U.S. companies to the export control list, subjecting them to an export ban of dual-use products. Among them are High Point Aerotechnologies, a defense tech company, and Universal Logistics Holding, a publicly traded transportation and logistics company. An additional 11 U.S. companies were added to the unreliable entity list, including the American drone makers Skydio and BRINC Drones, banning them from import and export activities as well as making new investments in China. In announcing its WTO lawsuit, the Commerce Ministry said Trump's new tariffs move “seriously violates WTO rules, seriously damages the legitimate rights and interests of WTO members, and seriously undermines the rules-based multilateral trading system and international economic and trade order.” The ministry called the tariffs “a typical unilateral bullying practice that endangers the stability of the global economic and trade order.” Beijing's previous tariff moves In February, in response to Trump's first 10% tariff, China announced a 15% tariff on imports of coal and liquefied natural gas products from the U.S. It separately added a 10% tariff on crude oil, agricultural machinery and large-engine cars. A month later, Beijing responded to Trump's second round with additional tariffs of up to 15% on imports of key U.S. farm products, including chicken, pork, soy and beef. Experts then said Beijing exercised restraint, leaving room for negotiations with Washington. By now, dozens of U.S. companies are subject to controls on trade and investment, while many more Chinese companies face similar limits on dealings with U.S. firms. While friction on the trade front has been heating up, the two sides have maintained military dialogue. U.S. and Chinese military officials met this week for the first time Trump took office in January to share concerns about military safety on the seas. The talks held Wednesday and Thursday in Shanghai were aimed at minimizing the risk of trouble, both sides said. ___ Tang reported from Washington. ...read more read less
