"The United States has no closer friend, no closer friend than Canada," Biden told Trudeau via an electronic video link with the Canadian leader and top aides. "That's why you were my first call as president (and) my first bilateral meeting," he said.
The two leaders "robust" agenda would address the COVID-19 pandemic, economic recovery, climate change, refugees and migration, fighting for democratic values around the globe and strengthening democracies at home, Biden said.
Trudeau welcomed the Biden administration, citing in particular Washington's renewed attention to climate change in contrast to former U.S. President Donald Trump.
"Thank you, again, for stepping up in such a big way on tackling climate change. U.S. leadership has been sorely missed over the past years," the Canadian leader said.
