Carbis Bay, UK: G7 leaders Friday opened their first in-person talks in nearly two years, with an expected pledge to donate one billion COVID-19 vaccine doses to poor countries on the agenda in a show of Western democratic cohesion.
The club of leading economies - Britain, Canada, France, Germany, Italy, Japan and United States - say a joint approach is the world's best chance for recovering from the global health crisis, and tackling climate change.
Welcomed by British Prime Minister Boris Johnson to the beachside summit venue in Carbis Bay, southwest England, the leaders posed for a family photo before opening their first session of talks on "building back better" after the pandemic.
The meeting presents a "huge opportunity" for global pandemic recovery, Johnson told his fellow leaders in opening remarks, as they sat socially distanced and without masks at a round table.
It would focus, he said, on "building back greener, building back fairer and building back more equal", with an emphasis on gender equality.
US President Joe Biden had set the tone, ditching Donald Trump's isolationist stance to ram home a message of resolve by the G7 and NATO against both Beijing and Moscow, as he heads into his first sit-down with Russian President Vladimir Putin next week in Geneva.
"I'm looking forward to reinforcing our commitment to multilateralism and working with our allies and partners to build a more fair and inclusive global economy," Biden tweeted from the G7 in Cornwall.
"Let's get to work."
COVID-19 and climate
Campaigners say the G7's vaccine donations pledge for this year and next - including 500 million US doses - is far too little, too late to end a pandemic that has claimed over 3.7 million lives worldwide.
"If the best G7 leaders can manage is to donate one billion vaccine doses then this summit will have been a failure," Oxfam said, insisting the world needs 11 billion doses.
But the G7 wants to rise to competing "vaccine diplomacy" efforts launched by China and Russia, with the Biden administration stressing it expects nothing in return for its donated jabs.
The leaders are also expected to outline more help for developing nations to build up infrastructure, as a counterpoint to the debt-fuelled spending by China in Africa, Asia and Latin America.
The initiative "will embrace a high standards, transparent, climate friendly, non-corrupt mechanism" for infrastructure investment in the developing world, a senior US official said.
"It will be an alternative to that which other countries, including China, are offering."
'Indestructible relationship'
Underpinning the US-led diplomatic revival, Biden and Johnson on Thursday adopted a new "Atlantic Charter", modelled on the pact signed by their World War II predecessors to help build a new world order.
Johnson dislikes the decades-old phrase "special relationship", arguing it makes Britain look subservient to Washington, telling the BBC instead that it should be viewed as "indestructible".
He also played down any differences with Biden over the restive British province of Northern Ireland, ahead of showdown talks between Johnson and EU chiefs on Saturday to tackle deep fissures opened up by Brexit.
British Foreign Secretary Dominic Raab hit back Friday after French President Emmanuel Macron launched a broadside over UK backpedalling regarding special post-Brexit arrangements for Northern Ireland.
Raab told Sky News that "change must come from the European Commission side" and that "we are not negotiating or haggling the integrity of the United Kingdom".
Late Thursday, more than 3,000 pro-UK loyalists staged a protest in Belfast against the "protocol" that effectively keeps Northern Ireland in the EU customs union and single market.
Marshmallows by sea
Johnson will hope to lighten the mood at a beach barbecue on Saturday, joined by his new wife Carrie and other G7 spouses, with a sea shanty band and toasted marshmallows around fire pits.
That will follow a reception for the G7 leaders Friday evening hosted by Queen Elizabeth II at Cornwall's Eden Project, an exhibition that showcases the world's ecological riches.
Safeguarding global biodiversity is another G7 theme this weekend, with the leaders set on an agreement to protect at least 30 percent of the world's land and oceans by 2030.
They will also debate aiding poorer nations to transition out of fossil fuels, in the build-up to the UN's COP26 climate summit in November in Scotland.
Like the G7, Britain wants COP26 to be held in-person, and announced that it plans to offer vaccinations to delegates from poorer nations if they cannot get them otherwise.
Greenpeace UK released a video shot with 300 illuminated drones over Cornwall, creating a startling display of endangered animals, to urge G7 leaders to stop mass extinctions.
"We need to see action, not just warm words, to tackle the climate and nature emergency," Rebecca Newsom, head of politics for the environmental group, told AFP.
"We need to see those tangible commitments this weekend - otherwise our world leaders are failing us," she said.
The G7 is also expected to adopt a UK plan to ensure schooling for another 40 million girls by 2025, after the pandemic destroyed educational opportunities for many around the world.
