President Donald Trump is on the verge of slapping new tariffs on Canada and Mexico while doubling a levy on China, moves that would dramatically expand his push to revive domestic manufacturing, tap new revenues and rebalance ties with the biggest US trading partners.

U.S. President Donald Trump is expected to decide on Monday what levels of tariffs he will impose early on Tuesday on Canada and Mexico amid last-minute negotiations over border security and efforts to halt the inflow of fentanyl opioids.

President Donald Trump said Mexico and Canada could not negotiate a reprieve from 25% tariffs scheduled to take effect on March 4. “No room left for Mexico or for Canada,” Trump told reporters Monday when asked if the U.S.’s North American neighbors could reach a deal to put off the duties. “They’re all set. They go into effect tomorrow.”
