On February 1, 2019, the U.S. government announced a 10% tariff on all goods imported from China, citing issues such as fentanyl. The Chinese government strongly opposed this, arguing that the unilateral tariff increase by the U.S. violates World Trade Organization rules and harms normal economic and trade cooperation between China and the U.S. In response to the U.S. measures, China imposed tariffs on certain imported goods originating from the U.S. starting February 10, including coal, liquefied natural gas, crude oil, agricultural machinery, large displacement cars, and pickups, with tax rates ranging from 10% to 15%.
