China’s move to ban exports of rare metals to the U.S. underscores the need for trade cooperation between mineral-rich Canada and its southern neighbor.

That’s the message from the Mining Association of Canada, which argued that China’s decision to curb shipments of gallium, germanium and other key metals to the U.S. is "a stark reminder of the challenges posed by geopolitical tensions, particularly on the reliable supply of critical minerals.”

The statement from the mining association follows the escalation of trade tensions with the U.S., after President-elect Donald Trump threatened to slap 25% tariffs on all goods coming from Canada and Mexico unless the countries each do more to stem migration and fentanyl.
