OTTAWA, July 29 (Reuters) – Prime Minister Mark Carney on Wednesday played down the idea of curbing oil ‌supplies to the United States to gain leverage ‌in a trade war, saying that would harm Canada’s reputation.

President Donald Trump, ​who has already imposed a raft of tariffs against Canada, on Tuesday said he did not care about renewing the U.S.-Mexico-Canada free trade deal. He is also threatening another round ‌of punitive measures later ⁠this month.

Last week Carney said he and Trump had agreed to intensify trade negotiations, adding ⁠that all options were on the table if the United States went ahead with its latest tariff threat.

Canada is a ​major shipper ​of crude to the United ​States and Carney, in ‌response to a question about potentially using oil as a bargaining lever, dismissed the idea.

“Being a reliable supplier is important. Canadians are reliable. Canadians can be trusted … we have many exports and commodities. One of the biggest commodities, arguably ‌the best, is trust,” he said.

“People ​trust us, and so when ​you’re the supplier of ​a key commodity, a key service, you ‌have got to think really hard ​about not ​supplying.”

The province of Alberta, which supplies most of the oil sent to the United States, has also said ​it will not ‌accept any action to curb exports of oil or ​impose export duties.
