TAIPEI, Taiwan (AP) — China has reiterated it could take “necessary countermeasures” after U.S. President Donald Trump decided to impose a 10% tariff on China for allegedly doing too little to stem the production of precursor chemicals for the drug fentanyl. The Foreign Ministry statement issued Sunday did not mention any specific retaliatory measures, but said “China calls on the United States to correct its wrongdoings, maintain the hard-won positive dynamics in the counternarcotics cooperation, and promote a steady, sound and sustainable development of China-U.S. relationship.” China says the U.S. action violates World Trade Organization rules and has vowed to bring a case before the body that governs global commerce.
