Divisions are deepening between the US and other western countries over Ukraine, and now trade.
The US President's slapped a 25% tariff on all Canadian and Mexican imports, and 20% on some from China.
Canada's responded by imposing the same amount back, which Donald Trump says he'll match again.
Former Trade Minister and Ambassador to the US Tim Groser told Kerre Woodham countries like Canada are fighting the US on trade, while trying to form closer security ties.
He says that the two strategies are inherently in conflict with each other – you can’t start a trade war with someone you want to curry favour with.
Groser told Woodham he argues that even if Trump was next to them right now, he also wouldn’t be able to say what the end game is.
He says it’s difficult to sift through and find the real logic of the situation, resulting in unprecedented uncertainty.
