Donald Trump has renewed threats to impose tariffs on imported cars after General Motors announced job cuts and plant closures.
The US President tweeted that tariffs were "being studied" and that duties could have stopped the GM closures.
Separately, the Trump administration warned it may raise tariffs on Chinese car imports.
The fresh trade threats come as Mr. Trump prepares to meet his counterparts at the G20 summit.
The US president has lashed out at GM over its plan to cut more than 14,000 jobs and close factories in North America.
