"We have to push back against the Chinese government's economic abuses and coercion that undercut the foundation of the worldwide economic system", he said.
Mr Biden said he was "grateful for Europe's continued leadership on climate issues over the last four years".
His speech came hours after a virtual meeting with other leaders of the Group of Seven (G-7) countries.
He declared that America had returned to multilateralism as he called on the U.S. and Europe to work together to counter economic and security challenges from China and Russian Federation. On Thursday, U.S. Secretary of State Antony Blinken spoke with his Quad counterparts - Japanese Foreign Minister Toshimitsu Motegi, Australian Foreign Minister Marise Payne and Indian External Affairs Minister Subrahmanyam Jaishankar - on Myanmar, the East and South China seas, North Korea, COVID-19, and climate change. We are in the midst of a fundamental debate about the future direction of our world. "But none of us should fear or resent these changes". In a statement on Saturday, the White House said Biden and his Cabinet will also meet virtually with Canadian ministers on a range of bilateral and global issues. "And I believe with every ounce of my being that democracy must prevail".
His enthusiasm for strengthening the trans-Atlantic alliance, at a time when the U.K.is charting a new course for its diplomacy in the post-Brexit era, fits in comfortably for Biden and USA national security adviser Jake Sullivan.
But Biden delivered harsh warnings about the threats he said are posed by Russian Federation and China.
US President Joe Biden has affirmed his commitment to improving ties with European nations and working together to face competition from China.
While welcoming reengagement by the US, France's President Emmanuel Macron said Europe must still step up to ensure its own security.
It will be the first official meeting between the two countries since Biden took office on January 20.
"We share democratic values and alarm over expanding repression, such as in Xinjiang. Competition with China is going to be stiff".
Macron said that the US for decades had been "totally focused" on Europe that but this had changed with the rising importance of Asia.
He said America and its allies "can own the race for the future" but to do so they must be "clear-eyed".
Trudeau has expressed disappointment at Biden's move to scrap the pipeline.
- US President Joe Biden will virtually meet Canada's Prime Minister Justin Trudeau Tuesday at a time of strained relations between the close allies. "Leadership and action on this matter by the transatlantic partners sends a powerful message to autocrats around the world", he said. "Britain is also going to be an increasingly assertive force in the Brexit era, aggressively standing up to China and Russian Federation". Trudeau had supported the project since before he became prime minister.
Gardiner noted that Johnson was the only world leader to specifically call out China over its treatment of the Uighurs.
But analysts also noted that while the USA defined democracy as essential, the Europeans did not describe it quite as centrally, focusing more on other issues instead.
