President Donald Trump announced a trade agreement with Japan on Tuesday, making it the largest U.S. trade partner to broker an accord as the White House threatens to impose tariffs on dozens of countries within days.

U.S. President Donald Trump’s trade deal with Japan has sparked fresh optimism that the global economy will manage to avoid getting hit with extremely elevated tariffs, even as many U.S. trading partners still don’t have agreements.

Japan will invest $550 billion in the U.S. and allow the U.S. to tax Japanese goods sold in America at 15 percent.
