Donald Trump has threatened to block Canadian aircraft maker Bombardier from selling jets in the US unless it begins manufacturing them in America.
Trump has accused Bombardier of relying heavily on the US market while Canada restricts American companies, and has previously threatened measures against the company's aircraft.
Bombardier says it supports tens of thousands of US jobs and works with around 2,800 American suppliers, while Reuters reports that aerospace experts question how practical a sales restriction would be.
