media captionBiden: US could 'work with Russia' over Covid, cyber crime and conflict
US President Joe Biden has declared that "America is back at the table" following the G7 summit of world leaders in the UK.
At a press conference on Sunday, Mr Biden said the summit had been "extraordinarily collaborative".
G7 leaders agreed on action to tackle China's human rights record and climate change after three days of talks.
Mr Biden said the organisation was in a "contest with autocracies" and welcomed its approach on China and Russia.
He also sought to distance himself from his predecessor – Donald Trump – who he said believed climate change was "not a problem".
"We had a president, the last [one] who basically said it's not a problem, global warming," Mr Biden said. "It is the existential problem facing humanity and it's being treated that way."

The world leaders attending the Cornwall summit signed a declaration calling on China to "respect human rights and fundamental freedoms", especially in the Xinjiang region, the north-western region that is home to the Uyghurs and other Muslim minorities.
Human rights groups allege China has subjected minorities in the region to mass detention, surveillance, and torture – something China strongly denies.
"We're in a contest, not with China per se… with autocrats, autocratic governments around the world, as to whether or not democracies can compete with them in a rapidly changing 21st century," Mr Biden said.
The G7 adopted a spending plan to support lower and middle-income countries in response to a similar Chinese scheme.
Chinese officials, meanwhile, warned G7 leaders that the days when "small" groups of countries decided the fate of the world were long gone.

The G7 also called for a transparent, expert-led study including in China, organised by the World Health Organization (WHO), amid claims Covid-19 may have leaked from a Chinese laboratory.
"We haven't had access to the laboratories," Mr Biden told reporters.
He said it was not yet certain whether or not "a bat interfacing with animals and the environment… caused this COVID-19, or whether it was an experiment gone awry in a laboratory".
Mr Biden also said the Russian President Vladimir Putin – who he dubbed an "autocrat" – was right to believe relations were at their lowest point in years. The pair are meeting in Geneva on Wednesday.
But he said the US could "work together with Russia" on issues such as Covid, cyber crime and conflicts.
What is in the G7 communique?
The G7 leaders published a 25-page communique summing up their "shared agenda" in key points. They included:
- Coronavirus: The headline pledge was to provide an extra one billion vaccine doses to poorer countries over the next year. They also committed to increasing global manufacturing capacity around the world, improving early warning systems for pandemics and supporting science to cut the time it takes to develop vaccines
- Help economies recover: The G7 countries said they would shift from supporting smaller countries' response to the crisis, to helping them grow and recover with jobs and investment
- Climate change: The leaders committed to a "green revolution" that would limit the rise in global temperatures to 1.5C. They also promised to reach net-zero carbon emissions by 2050, halve emissions by 2030, and to conserve or protect at least 30% of land and oceans by 2030
