In a rare bipartisan move, two senators have introduced legislation in the latest attempt to fight the flow of fentanyl and its precursors into the United States from China, Mexico and through other borders — one reason that President Donald Trump has given for his new tariffs.

Beijing will "resolutely counter" U.S. pressure on tariffs and the fentanyl issue, China's foreign minister said on Friday, adding that major powers "should not bully the weak", in a veiled swipe at the Trump administration's foreign policy.

Trump during his address to Congress said that Canada and Mexico ‘have allowed fentanyl to come into our country at levels never seen before.’

The White House announced on Monday that it will impose increased tariffs on China, citing the ongoing fentanyl crisis in the U.S. as the driving force behind the move.
