As U.S-Canada relations strain, P.M. Mark Carney looks to rebuild ties with China

A leader of the Canadian government is visiting China this week for the first time in nearly a decade, a bid to rebuild his country’s fractured relations with the world’s second-largest economy — and reduce Canada’s dependence on the United States, its neighbor and until recently one of its most supportive and unswerving allies.

The push by Prime Minster Mark Carney, who arrives Wednesday, is part of a major rethink as ties sour with the United States — the world’s No. 1 economy and long the largest trading partner for Canada by far.
