On March 12, the Ministry of Foreign Affairs held a regular press conference, and some reporters asked questions about the official entry into force of the 25% tariff imposed by the United States on all imported steel and aluminum. Foreign Ministry spokesperson Mao Ning said that China always believes that there is no way out for protectionism, and there is no winner in trade wars and tariff wars. This is also the general consensus of the international community. The US move seriously violates WTO rules and seriously damages the rules-based multilateral trading system, which is not conducive to solving the problem. China will also take all necessary measures to safeguard its legitimate rights and interests. (Sun Yue Tan Tian)
