i'm rico hizon in singapore. the headlines: can they find common ground? the global challenges stack up as world leaders begin their crucial 620 summit injapan. seconds out, round two. the next batch of democratic politicians go head—to—head in a presidential debate. i'm ben bland in london. also in the programme: after the death of oscar martinez and his daughter valeria, we report from america's southern border on the migrants still risking their lives in hope of a better future. and we visit western china, where communities are using green

power to try to hold back the desert sands. good morning. it is 7:00am in singapore, midnight in london, and 8:00am in osaka, where leaders of the world's biggest economies have gathered for the 620 summit. in just a few hours‘ time, they will gather for the official family photo which will get the summit underway. trade wars, iran and climate change are all topics that are likely to dominate. for more on this, i am joined now by our correspondent rupert wingfield—hayes in osaka. rivets, even before the summit begins, already tensions building

with president trump ruffling a few feathers —— rupert. with president trump ruffling a few feathers -- rupert. that's right, rico. president trump on his way he has managed to sort of throw down the gauntlet or say some fairly controversial things about several of the people that he is going to meet here today. so he managed to say to indian prime minister narendra modi that he has imposed unacceptable narendra modi that he has imposed u na cce pta ble ta riffs narendra modi that he has imposed unacceptable tariffs on the united states' products, and they must withdrawn immediately. to his japanese ally and a host of this, shinzo abe, the japanese prime minister, mr trump tweeted that japan wouldn't come and help us if there was a war, it would just sit at home and watch it on a sony television. and of course, the other thing that is overshadowing all of this, he also said that germany was freeloading, he is going to be meeting angela merkel here as well. but the thing that is overshadowing the whole of this g20 meeting,

really, rico, is the trade war with china, and everybody now waiting to see whether mr trump and president xijinping are going to hold a meeting on saturday, and whether that meeting is going to lead to some sort of truce, at least, in the ongoing trade war, which has now been going on since last year. absolutely, this ongoing trade conflict between two of the world's biggest economy is basically also dictating market movement. but other topics that will also be discussed there, could it also include brexit? brexit will be discussed, no doubt. theresa may, the british prime minister, is the here. but this is her swung back swa nsong. minister, is the here. but this is her swung back swansong. she will be leaving office in a few weeks people ‘s time and will be replaced by a new conservative party leader. so it will be discussed, but everybody here realises that she is now a lame—duck prime minister. but we did hear the japanese foreign minister in an interview with the bbc yesterday talking directly about brexit, and the prospect of a no deal brexit, which could happen as

early as 31 october if britain was to leave the eu without a deal then. and he made it very, very clear that the japanese government is absolutely opposed to a no deal brexit, and he warned that if it happened it would do serious damage to japanese business interests in the uk, and therefore to the uk economy. what about us - iran tensions, and climate change? will this also feature high on the g20 summit agenda? yes, i mean, iran is bound to come up. we have russia, china and the us leaders all here in the same place, everybody deeply concerned about the tensions in the arabian gulf, the attacks that have taken arabian gulf, the attacks that have ta ken place arabian gulf, the attacks that have taken place on oil tankers in the streets of hormuz, the shooting down of the us drone over the straits of hormuz last week so it is very much expected that president sharp will speak to both president xi and president putin about that because

those are two countries, iran and china, which have close ties to the iranian regime, and america said it wants to hold talks with iranian government, the iranian government set absolutely not. when it comes to climate change, the french government in particular has wanted to have that on the agenda here and wants the 620 leadership to reaffirm their commitment to the paris climate record. president macron is coming here absolutely without at the top of his agenda and he has said if it is not in the final communique, he may refuse to sign it. many issues on the plates of the 620 it. many issues on the plates of the g20 leaders. thank you so much for the update from 0saka, the sight of the update from 0saka, the sight of the 620 the update from 0saka, the sight of the g20 meetings. and we will have more on that meeting and what is at sta ke more on that meeting and what is at stake with the trade war coming up injusta stake with the trade war coming up injust a few stake with the trade war coming up in just a few minutes. let's take a look at some of the day's other news. us president trump says he is seeking a possible delay to the 2020 us census. this is after the supreme court blocked his administration from adding a question about citizenship.

mr trump tweeted that it was ridiculous that the government could not ask for citizenship information, but human rights groups claim a citizenship question could deter immigrant households from taking part in the census. also making news today: the islamic state group said it carried out two suicide bomb attacks in the tunisian capital, tunis. 0ne police officer was killed. several other people were injured. the attacks came as officials announced that the country's 92—year—old president, beji essebsi, had been taken to hospital after suffering a severe health crisis. indonesia's constitutional court has confirmed the victory of presidentjoko widodo in april's presidential election. it dismissed accusations of cheating made by rival prabowo subianto. thousands came out in support of the defeated presidential candidate, protesting peacefully outside the court. but the panel ofjudges upheld president widodo's victory, when he won 55.5% of the vote.

in turkey, istanbul new mayor, ekrem imamoglu, has celebrated with thousands of his supporters after officially being elected to the city's top job. he is a member of the main opposition republican people's party, and won decisively against president erdogan's party in the re—rerun of the mayoral elections on sunday. england are heading to the women's football world cup semi—final after beating norway 3—0. the lionesses took the lead just three minutes in, and dominated possession. they will face either france or the united states in lyon on tuesday. 0n newsday yesterday, we brought you the tragic story of oscar and valeria ramirez, the father and daughter who drowned while trying to cross into the united states from mexico. their deaths add to the rising number of migrants killed trying to make the journey.

0ur correspondent chris buckler reports from the border, where he has been speaking to other people hoping to get to america. behind the barriers, just across the rio grande, are the families searching notjust for a home, but a country. every day they gather here, just on the edge of america, in the searing heat, waiting for the opportunity to cross the border and make their case for asylum. but that can take months, and they know many, including president trump, want to reduce the number of immigrants entering the us. he says, as central americans, we are asking the president to understand we fled our country because it's becoming communist, and we are being politically persecuted. this family have travelled

from honduras, and they spent time here with 0scar ramirez and his daughter valeria in the days before they drowned trying to cross the river into texas. translation: she was with us. my children had been spoiling the baby. they were here, right next to me. the baby was so cute. he says, i told them they had to be patient, that they shouldn't be taking a decision that could jeopardise their lives. officials from el salvador have arranged for oscar and valeria's bodies to be returned to their home country. lawyers here have also been arranging for practical and psychological help for his wife, tania vanessa. how is she? she's, well... i cannot tell you she's good, because she's not. she's too young.

she's pretty... i don't know how to describe her shape. everyone here is relying on help, and it is at meal times you get a sense of the numbers needing that support. this is just one small part of matamoros, a sprawling city that is now full of people who have ended up stranded. they can't cross this border bridge, and they can't fulfil their american dream. this boy from central america wants to be an architect. he says he would like to build a community of houses, because it is very painful to see people living on the streets. but everyone can't have a home in the united states, and it is not only president trump who says these borders need to be defended. from the other side of this river, many families will only ever be able to look and hope. and in the past couple of hours, the united states house of representatives has approved $4.6 billion in emergency aid to ease the migrant crisis on the nation's southern border.

it comes a day after the senate passed the measure. the democrats had wanted additional language to ensure better protection of migrant children, but conceded to the republicans. the bill will now be sent to president trump to be signed into law. in a couple of hours from now, the next ten democratic presidential hopefuls go head—to—head in a televised debate in the united states. on wednesday, millions watched as the first ten hoping to take on donald trump in 2020 debated live on tv. key frontrunners joe biden and bernie sanders are up shortly, but let's take a look at some highlights from the first debate. when people come to this country, they do not leave their human rights at the border. all the american citizens out there who feel you are falling behind or feel the american dream is not working for you, the immigrants didn't do that to you. the big corporations did that to you. healthcare is a basic human right, andl you. healthcare is a basic human right, and i will fight for basic

human rights. we are going to free ourselves from the dependence on fossil fuels, ourselves from the dependence on fossilfuels, and ourselves from the dependence on fossil fuels, and we're going to put farmers ranchers in the drivers seat. we are the first generation to feel the sting of climate change, and we are the last that can do something about it. this president is literally, every single day, ten minutes away from going to war, one tweet away from going to war. jane o'brien is in miami for us, and we spoke earlier about what is in store for the second debate, which features the youngest and the oldest candidates in the race. well, you know, the energy that that dynamic is creating, you can probably hear behind me, those are all supporters for andrew yang. now, he's another younger candidate, he's in his 40s, and he will be hoping for a breakout moment, as clearly his supporters are too. and this dynamic between the older

candidates, bernie sanders, joe biden, both in their 70s, and then pete buttigieg, who is in his 40s, andrew yang, the only asian—american on the stage tonight, but representing the fastest growing demographic in america. we are going to see a fascinating debate. can these older candidates appeal to this younger generation, who are desperately looking for somebody to inspire them, to get out the vote in 2020, and really serve as a contrast and a marked difference to the presidency of donald trump. that's just one of the dynamics. we also have the tug—of—war between the centrists, represented by joe have the tug—of—war between the centrists, represented byjoe biden, and the left of the party, represented by bernie sanders. he's got his work cut out for him tonight, because another progressive leaving in the polls is elizabeth warren, the senator from massachusetts. she was on stage last night, did a very strong showing. it's up to him now to show how

different he is from her. so everything to play for in these first debates. and just looking back to the one that's happened already, it was interesting that none of them really seemed to take aim atjoe biden, despite him being, you know, significantly way out in front in the polls. he wasn't even mentioned. he was watching, though, and that's a very good point, because he is out in the polls. and i think at this stage what the candidates are very mindful of is that they don't want up mindful of is that they don't want up they want to focus on donald trump. he is the enemy, he is the person they actually want to defeat, and of course they've got to survive these debates without having any gaffes or any policy blunders that could either undermine the candidate who does get the nomination, or come back to bite them if they get the nomination. so it's about promoting themselves, but also making sure that they remain intact and viable going ahead.

you are watching newsday on the bbc. still to come on the programme: the desert frontline. how communities in remote western china are fighting back against the sands of time. members of the neo—nazi resistance movement stormed the world trade center armed with pistols and shotguns. we believe that, according to international law, that we have a rightful claim in certain parts of this country as ourland. i take pride in the words "ich bin ein berliner." chapman, prison—pale and slightly chubby, said not a single word in open court. it was left to his lawyer to explain his decision to plead

guilty to murdering john lennon. he believes that onjune 8, god told him to plead guilty and that was the end of it. the medical research council have now advised the government that the great increase in lung cancer is due mainly to smoking tobacco. it was closing time for checkpoint charlie, which, for 29 years, has stood on the border as a mark of allied determination to defend the city. this is newsday on the bbc. i'm rico hizon in singapore. and i'm ben bland in london. our top stories: world leaders have been arriving ahead of the g20 summit injapan. trade wars, iran and climate change are all topics likely to dominate the meeting. the second democratic presidential debate will get under way in the next few hours. ten candidates will go

head to head in miami. let's take a look at some front pages from around the world. let's start with hong kong's south china morning post, where all eyes are on the us and chinese presidents' meeeting at the g20 summit in osaka, japan. it reports on both countries tentatively agreeing to a truce in their trade war, but a source questions the reality of this. to the international edition of the new york times, which looks at the alleged crimes of the former president of gambia, yahya jammeh. human rights advocates are collecting firsthand accounts of abuses so that he can be brought to trial. and finally, the front page of the philippine daily enquirer tells us the government has bought in new legislation that will enable students in manila to travel for free at certain hours of the day.

those are the papers. now, ben, what stories are sparking discussions online? is online? it about a separation? that online? one is getting a lot of interest, that one is getting a lot of interest, ricoh, butanother one that one is getting a lot of interest, ricoh, but another one is just coming through that has ramped up just coming through that has ramped up the trending list. the british designer, jony ive, who's credited with helping to turn apple into the world's most valuable company over two decades, is leaving to set up his own business. mr ive, who designed the apple mac, ipod and iphone, will leave later this year to start a creative company called lovefrom, with apple as its first client. this comes at a time when investors have been worried about falling iphone sales. as we heard earlier, leaders from the g20 nations are meeting, but the summit is being overshadowed by tensions between two of its biggest members. the us—china trade spat has dominated headlines in recent weeks. donald trump and chinese president xijinping are due to meet on saturday, the big question is — will it be a showdown

or a truce? ive no for more on this i'm joined by shehtha chakraborty ive no chakraborty she's a risk and behavioural scientist. she is based in dc butjoins us from oui’ she is based in dc butjoins us from our studios in hong kong. looking at the behaviours of both leaders ahead of this g20 summit, will it be a showdown or a truce? the world is watching their interactions very carefully. ultimately what's going to be most interesting is to what thejoint to be most interesting is to what the joint statements will be coming out of their meeting on saturday. if you rememberfrom out of their meeting on saturday. if you remember from their last g20 meeting in buenos aires, the two state m e nts meeting in buenos aires, the two statements that were released were inconsistent p1 of the things that the us expected from china was that agricole projects will be bought and imported. —— agricultural. that was missing from the chinese statement. the consistency will be crucial following their meeting on saturday.

of course, there are a lot of industries being impacted here with this ongoing global trade war between two of the world ‘s biggest economies, and it has major implications for the global food supply chain? that's exactly right. there are real world implications as we watch the spectacle between these two leaders. we often forget the farmers, the beginning of the chain, and the consumers are the ones really being impacted and are suffering. in the us, the last g20 summit meeting and the tariffs imposed resulted in a $16 billion buyout for us farmers. there were some unexpected positive consequences that came out of that. a lot of the food surpluses, perishable food items were able to be bought out and spread to food banks and those in low income areas

in the united states that would benefit from that additional food. that said, the opposite happened in china. those most influenced by increasing food prices really suffered from the price of an apple doubling, for example. that in addition to a lot of diseases like swine flu impacting animal agriculture in china is resulting in real suffering in these populations. also this has consequences on food security with hundreds of millions of people undernourished. we have enough food production for the current global population to be fed but despite that, 800 million people go undernourished annually. that is a food distribution issue. when you have trade wars like this, the ripple effects are increased distribution issues on a problem thatis distribution issues on a problem that is already severe. as you can imagine, the impact of these trade wa i’s imagine, the impact of these trade wars will continue to exacerbate that significant issue that impacts a global very interconnected global supply chain. this will be made that

much worse as we think about how the planet is warming, climate change is very much on the agenda and it's being discussed at the two biggest looters that are meeting at this g20 summit, the us, president donald trump, and president xi, are not having the necessary conversation around how these two regional hegemony are going to address the issue of food production, agricultural production and the future where it's going to be increasingly more difficult to do so. increasingly more difficult to do so. thanks for your insight, joining us so. thanks for your insight, joining us from our hong kong studios. right across northern china, isolated communities are trying to hold back the desert. the cutting down of forests, pushing too much livestock over fragile land, climate change and overuse of water have exacerbated the problem. sandstorms engulfing beijing and even travelling across the water to south korea have been the result of widespread degradation. however, in recent times, those who live at the front line have had considerable success in slowing the moving sand. the bbc‘s china correspondent stephen mcdonell travelled to western china's gansu province.

china's vast deserts are constantly spreading. deforestation, overgrazing and climate change have all made the situation worse. throughout china's arid north, there is evidence of human beings struggling against the moving sands and losing. this sand dune is threatening these ancient ruins, with the community long since abandoned. there are people who still live in this area and this woman and her husband moved here from an even more inhospitable place, where everyone has now abandoned their old village. their growing grapes to become raisins. ——

they are. the chinese government has thrown massive resources into helping communities put in green buffers, replacing trees and grass cleared by past generations. in the early stages, mistakes included choosing the wrong species or only one type of tree. some plants used to much water. but in recent times, they're having much more success. —— too. out here, you get an idea of the size of the challenge for people who wa nt to size of the challenge for people who want to live in this area. with this

wind blowing the tops off these mountains of sand. and yet some scientists say that it's human interaction which exacerbated these problems in the first place, and they're now questioning whether or not in some of china's most harsh regions, may be the time has come to have less people in order to take the pressure of the environment. fewer buildings, fewer farm animals and fewer people would draw on less precious water and ease the load. with the right balance, communities could still thrive here. stephen mcdonell, gansu province, western china. you have been watching newsday. i'm rico hizon in singapore. i'm ben bland in london. and before we go, take a listen to this. it's not your average pop song. yes, it's catchy, but this girl band is is made up entirely of grannies,
