Canada's Finance Minister François-Philippe Champagne said on Thursday that the discussions on tariffs did come up during a G7 finance leaders' meeting, even though there was mention of them in the final communique that was published.

Tariffs are an expected topic of discussion at a meeting of the top U.S. and Canadian finance advisers late Wednesday at the G7 gathering in Canada's Alberta province.

"The G7 matters, especially if we agree China is our main competitive issue and adversary," Flavio Volpe, president of the Automotive Parts Manufacturers' Association said.
