As US adherent, Canada cannot gain much from trade with China
As neighboring countries and close partners, Canada and the United States share common interests in various fields. But despite that, the two countries' relations have seen twists and turns, including trade disputes, recently.
The US administration has adjusted its foreign policy, making settling trade disputes with other countries its priority. The US has been exerting enormous pressure on most of its trade partners, including Canada. The US president even took a jibe at Canadian Prime Minister Justin Trudeau at the G7 Summit in Quebec, Canada, in June, revealing the two leaders' tenuous personal relationship.
The US economy is about 10 times the size of the Canadian economy, and Washington has a dominant political and economic influence across the world. And since Canada is highly dependent on the US economy, it even has to accept most of the US' diplomatic demands.
