He said the United States will "work in lockstep with allies and partners". "And we're turning a corner and the countries we call the West are drawing together and combining their formidable strength and expertise once again".
"We can no longer delay or do the bare minimum to address climate change", Biden said, just hours after Washington formally returned to the Paris Accord.
The cancellation of the Keystone XL pipeline project on Biden's first day in office has also been a recent sticking point in Canada-U.S. relations.
The chummy relationship between Mr Biden and Mr Johnson was on full display when the British PM joked with the President that his campaign stole the British government's slogan "build back better".
US President Joe Biden has affirmed his commitment to improving ties with European nations and working together to face competition from China.
For instance, Chinese companies should be held to the same standards as those in the U.S. and Europe, Mr Biden said, citing publicly disclosing their corporate governance structures and abiding by anti-corruption practices as examples.
"I'm delighted that America under President Biden's leadership has rejoined the Paris Agreement", Johnson said.
Sullivan has been advising Biden to create "a position of strength" by teaming up with European allies to face the challenges posed by China and Russian Federation.
This echoed the text of the G-7 joint statement, which pledged to "consult with each other on collective approaches to address non-market-oriented policies and practices", while vowing to engage with China and others to support a fair and mutually beneficial global economy.
German Chancellor Angela Merkel said the United States and Europe need a "joint agenda" on China, while warning that their interests would not always converge.
"In particular multilateralism is boosted through the change in the USA government - the Biden administration has already demonstrated this with its first decisions" on returning to the Paris climate accord as well as lending support once again to the World Health Organization, she said.
This echoed Biden's own declaration that "the trans-Atlantic alliance is back", and hinted at a new direction of global relations, under which the US and its European allies align their foreign policies to adapt to the new realities, including a gravitational shift toward Asia.
In Friday's speech to the Munich event, Biden said that the world is at "an inflection point" between those who argue that autocracy is the best way forward to tackle the challenges of the times - such as COVID-19, the economic crisis and climate change - and "those who understand that democracy is essential" to meeting those challenges.
He added: "We must demonstrate that democracies can still deliver for our people".
"Europeans will no longer look at the USA as they once did", he says.
While welcoming reengagement by the US, France's President Emmanuel Macron said Europe must still step up to ensure its own security.
But Mr Rasser said it was relatively low-hanging fruit for the United States and Europe to work together to shape technology norms, among other things.
Biden's attempt to unite Europeans on the basis of fighting "a common enemy" is also sending a message to the American people in a bid to distract them from brewing domestic social and economic problems, according to Graziani.
"Our partnerships have endured and grown through the years because they are rooted in the richness of our shared democratic values".
