What ultimately influenced U.S. President Donald Trump’s decision last week to delay the tariffs he planned to impose on Canadian imports was arguably Canada’s announcement of targeted retaliatory tariffs on U.S. exports, strategically designed to affect Republican-leaning states the most. But the measures that may be enough to make Mr. Trump pause may not be enough to make him back off permanently.
. . .
Consequently, unless retaliatory measures pose a significant economic threat to the United States, Mr. Trump is likely to proceed with imposing tariffs on trading partners with which the country has large trade deficits, such as China (US$350-billion), Mexico (US$130.6-billion), Canada (US$100-billion) and the European Union (US$200-billion).
The key challenge for Canada – and other U.S. trading partners – is clear: to design a package of retaliatory tariffs and countermeasures that maximally affect U.S. economic interests. One effective strategy to do so is targeting the U.S.’s massive and rapidly growing service trade surplus.
Oil is the big one, immediate effect and wide spread. Make the local producers sell to Europe and Mexico. They won’t want to because so much of it is shale oil, but it’s better for everyone, even after Trump is gone.
