A majority of pollsters surveyed by Hill.TV's "What America's Thinking" said President Trump Donald John TrumpBiden on Trump's refusal to commit to peaceful transfer of power: 'What country are we in?'

Thirty-one percent of the pollsters chose Canada, while 28 percent said they wanted to see Trump make more of an effort with Mexico.

Seventeen percent said relations with China should be improved, and 13 percent said the same of Russia.

The survey, conducted July 9-13 among 21 pollsters, comes as relations between the U.S. and Canada have hit a rough patch amid increased trade tensions.

Trump lashed out at Canadian Prime Minister Justin Trudeau at last month's Group of Seven meeting in Quebec, calling him “very dishonest & weak.”

The president also slapped tariffs on steel and aluminum imports, including those from major U.S. trading partners like Canada, Mexico and the European Union.

Trudeau, in turn, retaliated with tariffs on U.S. goods that took effect July 1.
