Tariffs

President Trump has suggested an import tax of up to 45 percent on goods made by U.S. firms overseas. But it's illegal to single out individual companies and it's unclear what form the tax would take.

The president met with corporate executives on Monday, promising tax cuts and regulatory relief. But he also warned CEOs against moving jobs to other countries.

Analysts say Trump is likely to kill off TPP, reshape NAFTA and impose tariffs. But economists fear those moves could set off a trade war.

The existing tariff system, which adds as much as 25 percent to the cost of American high-tech exports, covers more than $4 trillion in annual trade, the White House says.
