Image source, EPAG7 leaders discussed theories about the origins of Covid-19 earlier today, according to the head of the World Health Organization (WHO).
In recent weeks the claim that the pandemic may have leaked from a laboratory in Wuhan has gained fresh attention.
WHO chief Tedros Adhanom Ghebreyesus says the leaders "raised" the lab-leak hypothesis and agreed to press China for more clarity on the issue.
A WHO investigation into the origin of the pandemic has not ruled out any theory behind the outbreak so far.
"We believe that all hypotheses should be open, and we need to proceed to the second phase to really know the origins," Dr Tedros said.
He said the origins of Covid-19 should be fully investigated out of "respect" for the victims of the pandemic.
There's nothing like a hard day of diplomatic haggling to work up an appetite.
After about six hours of talks today, the G7 leaders and their guests have made their way down to the beach at Carbis Bay for a barbecue.
Smoke from the grills is obscuring a clear view of who opted for what - but a number of local delicacies are said to be on the menu.
The atmosphere may be relaxed but security is not

This evening the G7 leaders were treated to a display by the RAF's Red Arrows aerobatic team. The jets set off at just after 20:00 BST and looped into an arc shape several times before splitting off.
As well as the G7 leaders, members of the public in St Ives looked up to the skies to watch the colourful display, cheering with delight when the jets moved into formation.
It's been a busy day for the Red Arrows, who had already performed a flypast at the Queen's official birthday celebrations earlier today.
The BBC's diplomatic correspondent James Landale said that from a diplomatic point of view, events like the Red Arrows help provide a structure around which you can base all the serious politics.
"These leaders are going to summits all the time," he said. "Most of them aren't as much fun as this. They get to bring their partners, there's a bit of a sense of occasion about this."

It's not just leaders of the G7 - the group of seven of the world's richest countries - that are at the summit in Cornwall this weekend.
The UK invited four other countries as guests - Australia, South Korea, South Africa and India to attend in order to "deepen the expertise and experience around the table".
Because of the coronavirus crisis, India's prime minister is joining via video conference call. But the other leaders arrived at the summit in person earlier today, along with UN Secretary-General António Guterres.

The G7 leaders are enjoying a barbecue beach party and nearby, so are Ruthie and Tony Goff.
The couple live on a clifftop in Carbis Bay which has a perfect view of the beach where world leaders are tucking into canapés, scallops and Cornish potatoes.
Ruthie and Tony have burgers and sausages on their menu - with lots of wine on hand for their friends.
Ruthie says “having a barbecue with amazing sunny weather like this, is the norm for us.... it just happens to be that these world leaders hundreds of yards away from us are doing the same thing.”
Some locals have criticised the summit due to the heavy security which has hugely restricted movements. But the Goffs are among residents embracing all the attention, with Ruthie describing it as "amazing" for the local area.
The G7 leaders are gathering on the beach for their "family photo" and a beach barbecue.
It seems the Red Arrows flypast has also been delayed.
We're expecting a flypast over the summit by the RAF Red Arrows in the next few minutes.
They will take off from RNAS Culdrose in Helston in Cornwall before flying over the coast east of Penzance and performing stunts over the Carbis Bay beach.
But locals in the area are being encouraged not to gather to watch the flyover because of coronavirus restrictions.

"We must be ready to respond to the next pandemic swiftly and equitably and that starts by preparing now," Ms Gates tweeted, external after the event.
A group of children gave a special performance for the partners of the G7 leaders earlier.
Under glorious sunshine at the open-air Minack Theatre in Porthcurno, the children performed an environmental parable about the harm of plastic pollution.
Carrie Johnson, Jill Biden and Brigitte Macron were all in attendance - but the need for secrecy meant not even the children knew beforehand who would be in the audience.
The US first lady later tweeted about the performance.

Image source, PA MediaMore now on the spending plan adopted by G7 leaders to rival China - a key issue dominating the agenda this weekend.
It's a plan designed to rival China's multi-trillion dollar Belt and Roads initiative, which funds infrastructure in many countries around the world.
The G7's Build Back Better World (B3W) plan would offer a "values-driven, high-standard and transparent" alternative, the leaders say.
But details of how the G7 plan will be funded are not yet clear. Germany's Angela Merkel says the group was not yet ready to release financing for the initiative.
The summit this weekend is for the leaders of countries in the G7 - that's the group of seven of the world's richest countries.
But some other countries' leaders have also been invited to attend as guests - and Boris and Carrie Johnson have been greeting them today.
India's Narendra Modi was also invited but plans to take part via video link due to the coronavirus crisis.

Andrew Segal
BBC South West, at Porthcurno
Image source, Andrew SegalThe hush-hush visit of the G7 leaders’ partners to Porthcurno in Cornwall meant many people who were visiting the village - and there were many, as it is a popular tourist spot - were not aware of what was happening up the hill at the Minack Theatre, a mere quarter of a mile away.
Police from a few English forces were around the area, including officers from Bedford, Cambridgeshire and the City of London; and were relaxed while talking to visitors and me about how this was quite different from their usual duties.
One officer (not pictured) said he was glad to be out, particularly in Saturday’s very sunny weather, as he’d spent three days of his G7 deployment “sitting in a car park”.
Excitement built up as a motorcade returned to the theatre and collected its passengers before they left the village through its narrow roads, with one security official confirming to me (when it was safe to do so) “It was Dr Biden.”
People who found out who it was were left with an interesting story about who passed them while they were in queues for pasties and ice cream.

Image source, PA MediaThe G7 group of the world's richest nations is set to agreed a plan to stop the world's largest companies avoiding tax by moving their operations between countries.
At the moment, a company can choose to put their headquarters in a country with a lower tax rate and take their profits there.
For example in 2018, Facebook, which has its international HQ in Dublin, paid £28.5m in tax to the UK, although its revenue was £1.65bn.
Under the G7 deal, companies could be taxed in any country where they make more than 10% profit on sales. Above that point, the company would have to pay 20% tax.
Another part of the deal is a global minimum corporate tax rate of 15%.
This is to stop nations undercutting each other's tax rate to attract multinational companies.
Ireland has operated a policy of attracting US technology companies to set up their headquarters there, chiefly through the offer of a low corporation tax rate of 12.5% (the UK's is 19% and set to rise to 25% by 2023).
Along with Facebook, Google has its international headquarters in Dublin's Grand Canal Quay, with TripAdvisor and AirBnB nearby.
Image source, PA MediaIn a meeting with UN chief Antonio Guterres at the summit, Boris Johnson has discussed the need for "joined-up global action" on climate change and pandemic preparedness, a Downing Street spokesperson says.
"They agreed on the need for countries to step up and make ambitious commitments to cut carbon emissions and phase out the use of coal," the spokesperson adds.
"They discussed a number of international issues including the situations in Yemen, Syria and Libya, the Cyprus peace process, the need for a return to democracy in Myanmar and Afghanistan."
US First Lady Jill Biden has joined Carrie Johnson and other partners of G7 summit leaders on a visit to a Cornish clifftop theatre.

The route is notorious for traffic jams as tourists flock to the area in the summer.
But with blue lights flashing and a posse of security guards on hand they managed to avoid the heavy traffic faced by holidaymakers.
Image source, Simon Dawson/Number 10 Downing StreetThey were there for a special performance by Cornish children about plastic pollution.
The local children weren’t told about the VIP audience until minutes before the guests arrived.
Apparently the players were anxious about misty Cornish weather but they needn't have worried, as there were clear blue skies over the stunning spot.
Image source, Simon Dawson/Number 10 Downing StreetSusie Kersley, who lives locally, says: "It's amazing, a little bit of excitement and puts Porthcurno on the map."
Friend Miranda Penhaligon adds: "It was mad, flashing blue lights, loads of cars.
"We are very isolated here and to see all these cars is just ridiculously amazing.
"We are just so excited, it's like a party."
