Mexico’s legislature deserves praise for its stand against Beijing last week, approving a new law that will impose tariffs of up to 50% on Chinese imports. Backed by President Claudia Sheinbaum, the measure targets roughly $125 billion in annual trade and signals that Mexico is no longer willing to tolerate China’s long-running trade abuses.

The Chinese Commerce Ministry understandably isn’t happy. Warning Mexico to proceed carefully, the ministry absurdly claimed that “China has always opposed all forms of unilateral tariff imposition.” The opposite is true. Under Xi Jinping, China has turned trade malpractice into a perverse art form.
