A major US mask manufacturer, 3M, says the government has asked it to stop exporting US-made N95 respirator masks to Canada and Latin America.
The request had "significant humanitarian implications", it warned, and could prompt other countries to act in kind.
The US invoked the Korean War-era Defence Production Act to demand that 3M provide more masks.
Canada's prime minister said stopping 3M's exports would be a "mistake".
