President Donald Trump announced a trade deal with Vietnam Wednesday that would allow U.S. goods to enter the country duty-free.

Trump has now extended the deadline for negotiations to Aug. 1 and tinkered with his threatened tariffs, leaving the global trading system pretty much where it stood three months ago — in a state of limbo as businesses delay decisions on investments, contracts and hiring because they don’t know what the rules will be.

The announcement came after President Trump in April proposed a steep 46% tariff on Vietnamese imports; he later paused those tariffs while talks continued.
