President Donald Trump on Monday threatened countries around the world to abide by any tariff deals they agreed to despite the U.S. Supreme Court ruling that struck down many of his far-reaching taxes on imports. And he said he wants a global tariff of 15%, up from 10% he had announced immediately after the ruling.

The court’s Friday decision struck down tariffs Trump had imposed on nearly every country using an emergency powers law. But the Republican president won’t let go of his favorite tool for rewriting the rules of global commerce and applying international pressure.

“Any Country that wants to “play games” with the ridiculous supreme court decision, especially those that have “Ripped Off” the U.S.A. for years, and even decades, will be met with a much higher Tariff, and worse, than that which they just recently agreed to,” Trump posted Monday on Truth Social.

One of Trump’s executive orders says he can bypass Congress and impose a 10% tax on imports from around the world starting Tuesday, the same day as his State of the Union speech.
