We'll come back to the Ukraine developments at G7 in a moment.

But on the topic of China, Australia's PM Anthony Albanese has spoken at a press conference where he said Australia had been concerned about Beijing's security and economic actions "for some time".

The prime minister cited the "chafing" or interception by Chinese fighter jets of an Australian military plane over the South China Sea last year. He also raised the ongoing detention of Australian journalist Cheng Lei who has been held in a Chinese jail for more than 1,000 days on unknown reasons.

Australia is part of the Quad security dialogue with the US, India and Japan. As we reported earlier, the group yesterday put out a statement pledging to uphold peace and stability into the Indo-Pacific region.

Australia "clearly support the status quo", Albanese said.

"We've expressed that concern in the past, we'll continue to do so. What we need to do is to make sure that we work in a way that enhances peace, security, and stability in the region," he said.

We understand the leaders are wrapping up their final working sessions where they discussed the war in Ukraine, and wider global security concerns.

G7 host, Japanese Prime Minister Fumuio Kishida, acknowledged Zelensky's presence in the meetings.

"We would like to deepen our discussion on how we should respond to the situation in Ukraine, and other challenges to peace and stability that the international community is facing," he said.

We're halfway through the final day in Hiroshima where G7 leaders are having their Ukraine meeting with Volodymyr Zelensky.

Here's what took place earlier:

• Zelensky appeared with the G7 leaders at their joint working session on the war in Ukraine
• French President Emmanuel Macron said the Ukraine leader's surprise appearance was a "game changer" in mobilising global support for Ukraine
• Already, the G7 leaders have mentioned more sanctions and the US has approved the option of allies sending F-16 fighter jets to Ukraine
• That's been a big win for Zelensky, who had been lobbying for the advanced aircraft for months
• He has already met with the leaders of the UK, India, France and Canada, and has a meeting with the US President this afternoon
• It's hoped his presence at the meeting could also induce more support from 'Global South' countries such as Brazil and India - also at the summit.
• The leaders of South Korea and Japan met this morning in another breakthrough in their warming relations

While Ukraine has dominated the agenda this weekend, the summit's meeting in Asia also highlights the G7 democracies' aims for a "free and open" Indo-Pacific.

Regional politics have been discussed on the sidelines, such as Japan and South Korea's warming relationship.

When President Yoon visited Japan in March – the first such visit by a South Korean leader since 2011- it infuriated many in his country, especially after he announced his government was going to foot the bill and pay the victims of Japanese forced labour and their families.

But it was only then that the Japanese – South Korean relation started to thaw. The two leaders have many shared regional worries and interests. Chief among them is the alarming rate at which North Korea is developing its nuclear program.

Many of the missiles fired by North Korea - and there have been many of late - land near or in Japanese territorial waters. Tokyo and Seoul will benefit from working together on intelligence sharing when it comes to Pyongyang’s aggression.

There’s also economic cooperation and securing supply chains. China’s increasing tension with Taiwan isn’t just a military threat that would pull in Japan, it’s also an economic risk with Taiwan producing most of the world’s semiconductors essential for tech industries.

These two countries all also strong US allies – something President Biden will no doubt reiterate when he sits down both leaders in a trilateral meeting.

The Ukraine working session is now under way between the G7 leaders, but earlier we saw other key diplomacy talks occur - including one between Japan and South Korea.

This morning, not very far from where our press centre is, Fumio Kishida and Yoon Seok-yeol jointly laid wreaths during their visit to a cenotaph dedicated to Korean victims of the 1945 atomic bombing of Hiroshima.

It’s the first time leaders of the two neighbouring countries have ever done this. Remember, these were Koreans killed while being forced to work for Japanese companies during Japan's occupational rule. That one event showed layers of symbolism and historical complexity.

Japan’s prime minister and South Korea’s president have met three times in the last three months. After years of near-total-silence, this tells you a lot about how fast this “new chapter” in their relation is going.

South Korean President Yoon said today that Mr Kishida's words had resonated in his country when he said that "his heart hurts" for the South Koreas who suffered from forced labour.

It is short of an apology which is what the South Korean people are asking for. But it also signals Japan’s acknowledgment of its very difficult past. And it's a nod to a new reality - that the two countries need to face a worrying future together.

The arrival of Volodymyr Zelensky has grabbed the limelight at this summit. It’s been the subject of plenty of speculation and discussion in the last 24 to 48 hours, and now here he is touring one delegation after another.

You can be pretty sure he’s going to dominate the agenda for the remaining hours of this gathering.

And from his perspective, that’s hugely valuable.

Not because it’s surprising that in the G7 there’s plenty of support for Ukraine’s cause – we’ve known that for some time. But with the fighter jets now in play, they are willing to sign up to something that is doing more than what has been offered so far, and is guaranteed to be long term.

It can’t be short term, because of the time it takes to train pilots and acquire the jets.

So Zelensky has that longer term, as he sees it, improvement in support from members of the G7 and elsewhere, and can try to persuade other leaders – whether they are from India, Brazil or elsewhere – who up to now have not been as supportive as they might have hoped, from a Ukrainian perspective.

He now has some valuable face time, as opposed to a conversation by phone or video link, to try and make his case.

As reported earlier, the leaders' meeting today on Ukraine comes after Russia claims victory in Bakhmut following a months long battle.

Russian President Vladimir Putin has congratulated the paramilitary Wagner Group, after the mercenaries claimed to have captured the eastern Ukrainian city.

On Saturday, Wagner's founder Yevgeny Prigozhin appeared in a video with his fighters claiming to have captured "the whole city".

But Ukraine immediately hit back at the claim, with Deputy Defence Minister Hanna Maliar writing on Telegram that heavy fighting continued in the city, though she accepted that the "situation is critical".

In the footage posted by Prigozhin explosions could be heard in the background, suggesting fighting continues close to the city, if not inside it.

Wagner mercenaries have been leading efforts to take the eastern city since August last year and previously claimed to have seized it.

But the city itself is of questionable military significance, and some analysts have suggested that Prigozhin - who is said to harbour political aspirations of his own - hopes to use any potential victory advance his own ambitions.

Earlier, the French president described Zelensky's attendance at the G7 as a "game changer" and a "way to build peace".

Zelensky arrived Saturday afternoon local time. Macron said it was his honour to have provided the Ukrainian president a French plane to get him to Japan from the Arab League summit in Saudi Arabia.

The US President is pictured here walking with Ukraine's leader to their working session on Ukraine - a roundtable held with the other G7 leaders.

The two leaders will also have their own meeting later this afternoon, after which they'll both give press conferences.

Volodymyr Zelensky has tweeted about his meeting, external with Justin Trudeau this morning.

He said they discused co-operation in defence and security, including training of Ukrainian officers within the UNIFIER Canadian training mission.

"I am grateful to Justin Trudeau and Canada for the assistance in demining our territories and for the prompt processing of our requests by the Government of Canada and Canadian manufacturers," he wrote.

According to the official schedule, the G7 leaders and Zelensky are now in their working session on the war in Ukraine.

Russia's claims to having captured the eastern Ukrainian city of Bakhmut overnight are the latest development in the fighting.

It no doubt underscores the aid and support the G7 leaders are pledging. Yes we've seen more sanctions pledged this summit, but the main boost for Kyiv is the US deciding finally to allow allies to provide their US-built F-16 fighter jets to Ukraine.

Zelensky had been calling for the fighter jets for months given Ukraine's current fleet are Soviet-era aircraft, limited in their missile scope.

Biden and Zelensky will also meet later today.

And while we're recapping the other key diplomatic talks this weekend - let's look at the eight guest nations invited this year.

For Saturday's group photo, Japan's PM ushered the leaders of Australia, India, Brazil, South Korea, Vietnam, Indonesia, Comoros (representing the African Union) and the Cook Islands (representing the Pacific Islands Forum) into position at the Miyajima shrine.

His guest list reflects attempts to woo what many call the "Global South" - a term used for developing countries in Asia, Africa and Latin America, all of whom have complex political and economic ties to both Russia and China.

The guests are here as observers, but these extra voices can bring a fresh perspective to the multiple crises facing the world’s richest countries.

“A stronger voice elevating our position is important. Having these face-to-face discussions and meetings really sets the tone and allows for relationships to be built,” said Mark Brown, Prime Minister of the Cook Islands.

The headlines of the summit have so far concentrated on the G7 countries plans to sanction Russia and counter China’s economic bullying.

But for many in the Global South, the real concern is the effects of global warming.

The people of Vietnam and Indonesia are trying to cope with their hottest summer on record. And the Pacific Islands are hugely vulnerable to rising seas and strong cyclones.

“I think climate change is not something that’s coming down the line, it's something that we live with, year after year, season after season. The impact that it has on our country is increased severity of hurricanes, storms, floods, but also the other extremes such as drought conditions,” Brown told the BBC.

“Our message is please hear the voice of the Pacific. Hear the call for greater action on climate change. This message has been repeated in a number of forums over a number of years. But we just have to keep pushing.”

One of the key diplomatic meetings from yesterday was the re-scheduled 'Quad'.

The Quadrilateral Security Dialogue is a strategic meeting between the United States, Australia, India and Japan. It was due to be held in Sydney this week but Biden had to cancel last minute to deal with the US debt crisis back home.

So instead the four leaders met up on Saturday.

They released a statement pledging to uphold peace and stability in the Indo-Pacific and "oppose unilateral actions seeking change in status quo by force" - a veiled reference to China's moves in the region.

They expressed a "serious concern at the militarisation of disputed features, efforts to disrupt other countries' offshore resource exploitation activities".

Beijing has increasingly laid claim to disputed territory in the South China Sea - and has built artificial islands in the waters which analysts say look like military posts.

The US’ decision to support the delivery of F-16 fighter jets to Ukraine is certainly a military boost for Kyiv – but the devil is in the detail.

The crucial questions are: how many, how quickly, and what weapons will the jets will come supplied with?

No-one doubts the ability of the F-16, which has more than proved itself in conflicts around the world, and will be a step up from Ukraine’s Soviet-era Mig-29s and Su-27s, which fly comparable missions.

However it’s not yet clear which of its capabilities will be available to Ukraine, while training and delivery will also be a challenge.

We've seen a significant meeting already this morning - with the South Korean and Japanese leaders holding talks.

Japan's PM Fumio Kishida and South Korea's President Yoon Seok-youl visited a cenotaph dedicated to the Koreans victims of the nuclear bombings in Japan during WW2.

The backdrop is highly symbolic as the two leaders try to repair a decades-long historic feud. Encouraged by Washington, this is the leader's third such meeting this year.

South Korea's leader also met with Korean survivors of the Hiroshima bombing on Sunday and said that the Japanese PM's earlier declaration that "his heart hurts" for those who suffered from forced labour under Japan's colonial rule resonated with South Koreans.

Yoon is also expected to meet Volodymy Zelensky later on Sunday for the first time.

As the final day of the G7 Summit begins here in Hiroshima, UK Prime Minister Rishi Sunak has released the following statement:

Tessa Wong

As we get ready for the last day of the summit, let's take a look at what happened yesterday here in Hiroshima.

A scene-stealing arrival: Volodymyr Zelensky surprised member nations - and the world's media - by turning up to the G7 summit a day earlier than he was expected. The Ukrainian president arrived on a French government plane, after a stopover in Saudi Arabia.

A commitment to the Indo-Pacific region: This was spoken about in a joint final statement and evidenced by the decision to invite countries such as Indonesia, India and the Cook Islands to the summit.

A message to China: Leaders took a strong stance against what they called "economic coercion" - using trade to bully other countries - and called for China to "play by international rules". Stressing their commitment to "economic resilience", they vowed to take steps to "reduce excessive dependences in our critical supply chains" - a reference to how the G7 countries are still inextricably linked to China in trade.

An angry response: China's foreign ministry responded by accusing the G7 of "manipulating China-related issues" and "smearing and attacking China".

Russia’s invasion of Ukraine dominated the agenda at last year’s G7 summit in Bavaria, Germany.

It took place in June 2022, just months after the war started. At the time,G7 leaders said they were “appalled” by Russia’s “war of aggression” and promised to provide financial, humanitarian, military and diplomatic support to Ukraine.

Ukrainian President Volodymyr Zelensky also addressed the summit via video-link.

This year, Zelensky arrived on the second day of the summit in Hiroshima, Japan, to greet the leaders in person.

The focus of the agenda has been the Ukraine war. Zelensky arrived hours after Washington said it would train Ukrainian pilots on American-made F-16 fighter jets and allow allies to provide the advanced warplanes to Kyiv.

The leaders also took a strong stance against what they called "economic coercion" - using trade to bully other countries - and called for China to "play by international rules".

They stressed their commitment to "economic resilience" and vowed to take steps to "reduce excessive dependences in our critical supply chains" - a reference to how the G7 countries are still inextricably linked to China in trade.

But they also said they wanted "constructive and stable relations" with China.

The G7 (Group of Seven) summit is an annual meeting of the world's seven largest so-called "advanced" economies – Canada, France, Germany, Italy, Japan, the United Kingdom and the United States.

Japan took over the G7 presidency from Germany in 2023, meaning it will host a number of meetings throughout the year, most notably this summit.

Throughout the year G7 ministers and officials hold meetings, form agreements and publish joint statements on global events.

The EU is not a member of the G7 but also attends, while representatives from countries including Australia, Brazil, South Korea and India have also been invited.

Russia was expelled from the group - previously known as the G8 - in 2014 in response to its annexation of Crimea.
