Donald Trump has finally unveiled his sweeping tariff plan - and many countries have been caught up in it.

The US President's announced 10 percent tariffs on almost all imports to the US.

They're much higher for some countries and products - including 25 percent on vehicles, 34 percent on China, and nearly 50 percent on some other countries.

Newstalk ZB senior political correspondent Barry Soper says Trump's focused on protecting the US from "unrelenting economic warfare" - but it's unclear what that could do to global relations.
