Trump Warns Countries That 'Play Games' with US Trade Deals Will Face Higher Tariffs

U.S. President Donald Trump on Monday warned countries against backing away from recently negotiated trade deals with the U.S. after the Supreme Court struck down his emergency tariffs, saying that if they did, he would hit them with much higher duties under different trade laws, according to Reuters.

Trump, in a series of social media posts, said he also may impose license fees on trading partners as uncertainty over his next tariff moves gripped the global economy and sent stocks lower.

He suggested that the U.S. could impose new license fees on trading partners, but did not provide any details.

A spokesperson for the U.S. Trade Representative's office did not immediately respond to a request for further comment on Trump's plans.

In Brussels, the European Parliament decided on Monday to postpone a vote on the European Union's trade deal with the U.S. after Trump imposed a new temporary import duty of 15% on imports from all countries.

EU goods under the deal would face a 15% U.S. tariff, with exemptions for hundreds of food items, aircraft parts, critical minerals, pharmaceutical ingredients and other goods, while the EU would remove duties on many imports from the U.S., including industrial goods.

Trump on Friday initially announced the temporary duty under Section 122 of the Trade Act of 1974 at 10%, but raised it to 15%, the maximum allowed under the statute, on Saturday.
