China warned Monday it would retaliate against countries aligning with the U.S. in ways that undermine Beijing’s interests, escalating tensions as the trade war expands beyond bilateral ties. The warning follows reports that the Trump administration plans to pressure allied nations to curb dealings with China using tariff negotiations. Trump recently paused tariff hikes on U.S. partners but raised duties on Chinese imports to 145%. China responded with 125% tariffs on American goods and new export restrictions. Officials accused the U.S. of “unilateral bullying” and vowed to defend international fairness. Analysts see little chance of a deal soon, despite Trump’s recent optimism.
