During an interview with Reuters, Trudeau also said that he was looking forward to president-elect Joe Biden bringing “a re-engaged United States in global circles” amid shifting global power struggles and pressing challenges facing the environment and free trade systems. “We’re seeing a world that is changing rapidly. The rise of a much more assertive and sometimes problematic China, the shifts in poles of power around the world, the rise and strengthening of Asia as an economic focal point. These are things that are needing to be responded to,” Trudeau said. Over the last four years, Trump often clashed with traditional allies on trade. He imposed tariffs on Canadian aluminum and steel and paralyzed the World Trade Organization’s role as global arbiter on trade by blocking appointments to its appeals panel.
