Also at the g7 as devastating fires take hold of the amazon rainforest, leaders agree to pledge more than 20 million to help save it. And a voyage of discovery how a vast mass of floating rocks in the Pacific Ocean could help save the Great Barrier reef. Welcome to the programme. This years g7 summit of World Leaders has ended. It was billed as the one where nobody would agree on anything. But with such low expectations, perhaps its no suprise that at the end of three days, they have been exceeded there was, in fact, some agreement and a warm atmosphere. Have a look at this body language. French president Emmanuel Macron, host of the meeting, and President Trump showing their closeness with this embrace at theirjoint press conference at the summit, which has come to an end with progress on at least two fronts. Firstly, on iran. Emmmanuel macron said a meeting could be arranged between President Trump and his counterpart, hassan rouhani. Heres mr macron speaking at a joint press conference with mr trump earlier. Translation what i told minister zarif and what i told president rouhani over the phone is that if he accepted to meet President Trump, im convinced that an agreement can be found. We know the terms, the objectives, now we need to get round the table and manage it. So, i hope that in the next few weeks, on the basis of these conversations, we can manage to organise a meeting at the highest level between president rouhani and President Trump. A meeting between american and iranian leaders would be the first since the us embassy was stormed and american diplomats were taken hostage in 1979, resulting in a aim day standoff and four decades of hostility. This is how President Trump reacted to the idea. President macron said hed like to see talks between you and president rouhani within weeks. Does that sound realistic to you . Could you see yourself in talks with iranians within weeks . Well, it does. I dont know the gentleman. I think i know him a little bitjust by watching over the last number of years whats happened. I tell you one thing, hes a great negotiator. But he, er. I think hes going to want to meet. I think iran wants to get this situation straightened out. But this idea hasnt gone down well in iran. This is taken from a breaking news caption on Iranian State television after that press conference. Informed sources iran rejects macrons suggestion on talks about its missile programme. But that doesnt mean it definitely wont happen. The second deal which could be on the table is an end to the us and chinas ongoing trade war. President trump was optimistic about reaching an agreement. Last night, very late in the night, i see an alert or, as you would call it, breaking news and it was that the vice chairman. Were not talking about somebody from china at a low level, the vice chairman of china came out that he wants to see a deal made. He wants it to be made under calm conditions, using the word calm. I agree with him on that. Now, usually, at these summits, we get whats called a communique, where leaders outline what has been agreed. This time however, we got this. A short, perhaps, a one page Statement Released by france. It says the seven countries are committed to open and fair world trade, and to Global Economic stability. So, not very much. This is peter baker. The New York TimesWhite House Correspondent peter baker. With all the differences with trump, the g7 leaders ended up releasing a largely general one page statement that added up to 264 words. The lastjoint statement under obama in 2016 was l263 words. Lets get an overview of what happened today in biarritz. Ros atkins was there. There are two ways we can look at the announcement from president macron that irans president rouhani is willing to meet donald trump, and Donald Trumps confirmation that he may be willing to meet president rouhani in the next few weeks. On the face of it, its simply a huge diplomatic coup for president macron. Bear in mind america and iran have been exchanging diplomatic barbs for months. And of course, the americans walked away from the Iran Nuclear Deal. There are some caveats, though. The meetings not definitely going to happen. If it does happen, weve learnt from the two north korea summits it doesnt necessarily lead to a significant shift in the situation. And even if the meeting were positive, actually finding either an evolved version of the Iran Nuclear Deal or a new deal is going to be a long, long process. Nonetheless, president macron is getting credit for bringing new ideas and passion to a situation which appeared to be stuck. On the issue of trade, well, Donald Trumps sounding positive. He says he thinks a deal can be done with china. But then hes also been scathing about the chinese in the last week as well. He acknowledged in his press conference this is a negotiating tactic. He says one thing, then he says another. Thats his prerogative, but it makes it hard to gauge. I would actually say the more significant statements on trade came from president macron. In his press conference, he detailed how he wants to see major reform of the World Trade Organisation and of World Trading regulations. And as such, he says intellectual property needs to be defended better and the whole system needs to be fairer. Those are two messages that could have a huge impact on how every country in the world trades with each other, but those were two messages also aimed directly at donald trump, because he has repeatedly complained of the unfairness of the system and of the fact American Intellectual property is under threat. So, significant announcements from Emmanuel Macron, but as to that trade war which leaders here have repeatedly been saying, please let it end well, were not really any the wiser. When it finishes is really within the wit of president xi and President Trump, and welljust have to wait on that. Before the Closing Press conferences, there was of course an announcement of money to help countries in the amazon tackle the fires. As well as the leaders of the seven big powers, other heads of government were also invited to join some of the discussions at the g7 and one of this years so called biarritz partners is watching the situation with the forest fires even more closely than most. Ros atkins has been speaking to the president of chile, sebastian pinera. There is a huge focus on the fires in the amazon and the g7 seems to have an appetite to do something, what would you like the g7 to do . We have a big emergency in the amazon. Remember, they are the land of the world. So we have to help brazil and the other amazonian countries to control these fires and that is something that has been discussed and we have already agreed that we will put a plan and we are in contact with all the amazon countries to bring help now. Basically, planes to get rid of the fires. Do you think president bolsonaro wants your help . Yes, he wa nts bolsonaro wants your help . Yes, he wants our help. But at the same time, he is very aware that he has to protect brazilian sovereignty. And we have compartmentalised both things. This last week, he talked about a colonial mindset when president macron was threatening to veto a big trade deal between europe and south america, did you agree with those comments . Well, they are two different things. One thing is to help brazil and other countries like bolivia, paraguay and peru to combat these huge fires. Another thing is a free trade agreement. Those two things should not be mixed. But those two things are mixed. But those two things are mixed because europe feels president bolsonaro is in part responsible for the fact these fires have escalated. Do you accept that he has played a part . Do you know that the amazon is a huge area. 7 million square kilometres. Every year, they have fires. This year is worse than last year, but within the average of the last 20 or 30 years. I dont think that president bolsonaro is responsible for this. I think that he is trying to do his best to combat these fires. But why do you say that . He is encouraging further mining in the amazon, further farming in the amazon, he has sacked the head of the Space Research energy who produced pictures showing that the fires were particularly bad. He gives the impression of someone bad. He gives the impression of someone who is not overly concerned with deforestation. Well, dont rely on impressions. What i am seeing is he has already sent more than 16,000 soldiers, brazilian soldiers to fight the fires. So i think that he is concerned about the health of the amazonian. But at the same time, he is protecting brazilian sovereignty. But how do you protect brazilian sovereignty at the same time as dealing with the problem that clearly affects the whole world . Would you like to see a different approach in south america that takes approach in south america that takes a regional approach to this problem, rather than a National Approach . Well, we are taking a regional approach. Right now, many countries in latin america are helping brazil and other countries to fight these fires. For instance, chile has sent many world planes to help combat the fires. But one thing that we have to ta ke fires. But one thing that we have to take into account is that we have to compartmentalise the respectful sovereignty at the same time realise that the amazon is the lungs of the world. And all of us are committed to protect that. No on the agenda here at the g7 is also the state of the global economy, there are significant economies pressures on the wells economy at the moment cani on the wells economy at the moment can i do accept President Trumps trade was making the pressure is worse . I think the trade war between china and the us is heading both countries. And it is hurting the whole world. I hope that this war will end soon. That is what we ask President Trump and president xi jinping in ourg20 President Trump and president xi jinping in our g20 meeting in osaka a few weeks ago. Unfortunately, things are not going in that direction. But i hope that we will be able to restore free trade because it is good for everybody, and to strengthen the role of the World Trade Organisation. This trade war was instigated by donald trump, can you help me understand how the trade war is impacting on the chilean economy . Well, the trade will represent a huge difference in approach on the part of china and the us. And it is impacting the whole world. The International Economy is weakened, we can now than a year ago. And chile is such an open country, it is so much integrated to the world but of course, we are being very, very affected by this trade war, that is why i hope and for the sake of the hold war whole world that this war will end. So you are concerned about the state of the global economy, we have some of the most powerful countries represented here at the g7. Are you satisfied that they can find any sort of common approach to the economy . Because it seems to me they really dont agree on the fundamentals of the problems. Well, why not the issue where they dont agree is this trade war . The us is saying that the chinese are taking advantage of the us consumers. And we are telling them that they have to sit down with president xijinping that they have to sit down with president xi jinping and that they have to sit down with president xijinping and reach that they have to sit down with president xi jinping and reach an agreement. Do you think the agreement. Do you think the agreement the americans are right, do they have a point . Dont put me between the americans and the chinese because we are good friends of both. Interested to ask you about donald trump, you have served twice now as chilean president , the first time before donald trump came to office and the second time after mr trump came to office, how has he changed International Politics, because we have never had an american president like this . Well, he has changed International Politics in every field. In the defence area, in the trade area. So of course, President Trump and president obama had a very different view of international affairs. As the improved international affairs, is hea the improved international affairs, is he a force for good . Well, he is convinced of his ideas. The important thing that we have to learn to live in a world where we do not always coincide. We have differences, we have to work it out. Do you wish you lived in a world where america didnt take these positions on Climate Change, iran and trade . I wish i could live in a world where everybody agrees that we are facing common problems and dramatic problems like Climate Change and global warming, and we should be working together from the very first moment, and we are not doing that. Speaking to the president of chile. Lets iam i am entering an abatement plan that consists of costs totalling five and ato consists of costs totalling five and a to immediately remediate the nuisance. As i detail in my judgment, this is the amount it costs that i am constrained to order Johnson Johnson to pay based on the particulars of a nuisance claim and the evidence that was presented at trial. Stay with us, we will get more details on that, they were expecting i7 more details on that, they were expecting 17 billion originally, they were suing theJohnson Johnson for that to be paid over 30 yea rs johnson for that to be paid over 30 years and we hearJohnson Johnson will appeal. So we will talk about that a little later. Stay with us on outside source, still to come. How this vast mass of floating rocks in the Pacific Ocean could help save the Great Barrier reef. Researchers in london are trying to learn how mosquitos communicate with each other. Once they do, they plan to develop systems to lure them away from Populated Areas to reduce the incidence of malaria and yellow fever. Our science correspondent pallab ghosh reports. For us, the whining sound is annoying. But for the mosquito, its a love song. The buzz helps the insects find mates and reproduce. What if we could learn to talk mosquito and sabotage their love lives . Malaria and yellow fever is spread through mosquito bites. The vast majority of cases are in africa. In 2017, 200 Million People had malaria. One way to defeat mosquito borne diseases is to turn their buzz against them. By disrupting their communications, the researchers believe that eventually, they can rid millions from the menace of mosquitoes forever. This is outside source, live from the bbc newsroom.
