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.

European Union negotiators have failed so far to achieve a breakthrough in trade negotiations with the Trump administration and may now seek to extend the status quo to avoid tariff hikes, five EU diplomats briefed on the talks said on Friday.
