U.S.-China Trade Tensions Rise as Trump Imposes New Tariffs After Supreme Court Ruling

Washington – Global trade faces renewed uncertainty after the U.S. Supreme Court struck down a key element of former President Trump’s tariff strategy, prompting a swift response from the current administration with new levies. China has urged the U.S. To cancel all unilateral tariffs in light of the ruling, escalating tensions between the world’s two largest economies.

Supreme Court Limits Presidential Tariff Authority

On Friday, February 20, 2026, the Supreme Court ruled that President Trump overstepped his authority when he imposed tariffs on nearly all U.S. Imports using a 1970s emergency statute . This decision represents a significant setback for Trump’s trade policies.

Trump Administration Responds with New Tariffs

In response to the ruling, the Trump administration immediately announced a new 10 percent global duty under a separate legal authority, which was subsequently raised to 15 percent on Saturday . These new duties are scheduled to take effect on Tuesday and are expected to last for 150 days, with some product exemptions.

China Calls for Tariff Removal

China has strongly criticized the continued apply of tariffs and urged the U.S. To cancel all unilateral measures. The Chinese Commerce Ministry stated it is conducting a “comprehensive assessment” of the ruling’s impact and called on Washington to lift the existing tariffs , . Beijing argues that “there are no winners in a trade war and that protectionism leads nowhere.”

Economic Impact and Market Reactions

The federal government has been collecting approximately $30 billion in tariffs each month, four times the amount collected before Trump’s return to the White House . Despite increased tariff rates – reaching the highest level in nearly a century – import taxes still represent a relatively small portion of overall government revenue, accounting for just over 5% in January.

A Harvard University working paper indicates that U.S. Importers are bearing the brunt of the tariff costs, rather than foreign suppliers as previously claimed . The dollar fell as traders sold U.S. Assets amid concerns over trade policy risks .

Upcoming Trump Visit to China

China’s warning comes just weeks before a planned visit by Trump, marking his first trip to the country during his second term . The timing adds further complexity to the already strained U.S.-China trade relationship.
