Major US trading partners scrambled over the weekend to finalize trade deals or lobby for extra time as President Donald Trump said he’s notifying about a dozen countries on Monday of the new tariff level on their shipments to the US.

The potential accord with the European Union, which would spare European goods the 50 percent tariffs Trump has threatened, is one of a few deals the White House could finalize this week.

“Vietnam will pay the United States a 20% Tariff on any and all goods sent into our Territory, and a 40% Tariff on any Transshipping,” Trump said on his social network. “In return, Vietnam will do something that they have never done before, give the United States of America TOTAL ACCESS to their Markets for Trade.”
