US President Donald Trump on Sunday accused Canada of wanting "the benefits of being a [US] State, without being one" in his first remarks since trade talks between Ottawa and Washington failed.

"They have also charged our great farmers, for many years, massive amounts of Tariffs. No more!!!" he wrote on his social media platform Truth Social.

What has happened in the US-Canada trade dispute?

In an ongoing trade dispute with the United States, Canada said on Saturday that it would introduce tariffs on several US products starting September 8.

The announcement comes in retaliation to the US imposing 50% tariffs earlier on Saturday on a broad range of Canadian products after the two sides failed to reach a trade deal on Friday.
