Trump told reporters in the Oval Office on Thursday that the latest tariffs on China would accumulate on top of the 10% tariff imposed on Feb. 4.

“It’s 10 plus 10,” Trump said in the Oval office. 

Additionally, Trump reaffirmed that he will proceed with 25% tariffs on Canadian and Mexican imports on March 4. 

In early February, Trump suspended the Canada and Mexico tariffs for 30 days to allow the countries to negotiate, but has now said that the two nations haven’t done enough to suppress the drug problem.

Trump was asked if he had seen progress in limiting the spread of fentanyl; he rejected the notion and said, “I don’t see that at all. No, not on drugs.”

In a post on Truth Social, Trump said that the supplemental tariffs on China will go into effect the same day as the tariffs on Mexico and Canada.

This proclamation comes a day after Trump told reporters that the Mexico and Canada tariffs were slated for April 2, but government officials reversed their stance and said a decision had not been made.

“As you know, he has his way of communicating, but as usual, we have a cool head and optimism that we can reach an agreement,” Mexican President Claudia Sheinbaum said in a press conference Thursday. 

The Chinese Embassy did not immediately respond to Fortune’s request for comment. 

According to the Centers for Disease Control, drug overdose deaths declined 24% to 87,000 in the U.S. between October 2023 to September 2024. 
“There are ongoing discussions with the Chinese, Mexico, and Canada,” a White House official said, Reuters reported. “We’ve gotten a good handle on the migration issue, but there are still concerns on the other issue of fentanyl deaths.”
