Trump also threatened a "massive" tariff increase, after China tightened its rules for exports of rare earths.

The US president's announcement comes after China pledged to impose restrictions on the export of rare earth minerals.

President Donald Trump is threatening punitive tariffs and canceling a meeting with Chinese President Xi Jinping due to a new Chinese rare earth minerals move.

After Beijing announced new controls on foreign-made products containing Chinese rare earths, Donald Trump threatened to impose an additional 100% tariff as soon as November 1.

Beijing says it will not back down in the face of threats, urging the US to resolve differences through negotiations.
