this is bbc world news today. i'm krupa padhy. our top story — china adds its voice to concerns about us tariffs. behind the smiles and handshakes — beijing warns washington that their trade talks could fail, if president trump goes ahead with his tariff plans. north korea's leader wants to stay at a luxurious hotel suite for his summit with donald trump in singapore — but who's going to foot the bill? remembering the victims of the london bridge terror attacks one year on — with a special service in london. also in the programme — the genetic test which could avoid chemotherapy for thousands of breast cancer patients. beijing has warned that trade talks between the us and china will fail if washington insists on imposing new tariffs. the g7 nations — meeting in canada —

have already stated that a trade war could start in a matter of days. president trump argues that the us has been "ripped off by other countries for years". our washington correspondent chris buckler has this report. the finance ministers were welcomed with the traditional canadian greeting. but despite the smiles, it was hard to escape the idea that someone was banging the drums of war. the message to the us, from the other big economic nations, who posed for this unhappy family photograph was simple. if you don't want a trade war, you have days, not weeks, to change your mind on tariffs. the americans have decided to, in our mind, take an action that is not at all constructive. it is actually destructive to our ability to get things done around tariffs, around steel and aluminium. president trump is introducing the steep tariffs on steel and aluminium on the grounds of national security. however, this old torpedo factory

in virginia is a reminder of the importance of notjust metals, but also allies. and with nations now threatening retaliatory tariffs on everything from bourbon to bluejeans, there are american families worried that they could pay the price of this fight. we do not buy american cars. we find the quality of german and japanese cars far higher and yes, we will end up paying more. we have had eu as an ally for as long as i can remember and building the tariffs will damage the relationship. president trump is continuing to campaign with the message that he is putting america first, but other nations say that does not have to be at their expense. the idea that we are somehow a national security threat to the united states is quite frankly insulting and unacceptable. president trump believes the policies he's pushing will ultimately be popular in american towns in cities. but he knows he also has to consider those international relationships

and when he meets the other g—7 leaders, at a summit in quebec next weekend, he is likely to face some awkward conversations. chris buckler, bbc news, alexandria. earlier i was joined byjohn hemmings — director of the asia studies centre at the henry jackson society here in london. i asked him where he sees this standoff going. on the surface it looks very disturbing. it appears that the trump administration is targeting the european union, japan, china, and the term is being used a lot more than i think people are co mforta ble more than i think people are comfortable with. there's a level of rhetoric in there. having said that, because of the white house's pushing, i think we are going to keep hearing it for awhile a while until we may end up looking at it. talk us through president trump

thinking here. how effective a strategy do you think this could prove to be? in terms of his tariffs on european union and japan, you have to remember that try now accou nts have to remember that try now accounts for i think 800 million tonnes of steel production, more than all other countries combined, the next one down is japan, about 100 tonnes. the us is somewhere down by the fourth. —— china accounts for i think 800 million tonnes. i think china is really the one, in terms of the eu and japan, my guess is it's midterms. we saw a very similar, very short—term tariffs on european union steel in 2003, i believe it was, march 2003 to december 2000 and four. the americans did it for short—term gain, i think they did very well in terms of getting swing

states like pennsylvania, i hire and west virginia. that's a short—term but the long—term with china will be the real battle. —— pennsylvania, ohio and west virginia. british prime minister theresa may has laid a wreath at the scene of the london bridge terror attack, to mark one year since eight people were killed by three men armed with knives. 48 others were injured when the attackers first drove a van into pedestrians and then stabbed people enjoying a night out. june kelly reports. on this first sunday of summer, hundreds gathered at southwark cathedral to reflect on a long night full of fear in london, 12 months ago. leading the public figures was the prime minister. eight lives were taken in the london bridge atrocity — one victim, james mcmullan, was british. christine archibald was from canada. ignacio echeverria was from spain. there were two australians, kirsty boden and sara zelenak, and three french victims — xavier thomas, alexandre pigea rd

and sebastien belanger. some were visiting london, others had made it their home. and at this interfaith service from the bishop of southwark, a simple, strong message. for those of us who profess faith, the invocation of holy names by those perpetrating these acts was not only profoundly distressing, but needs to be rejected. and there were the memories of local people. the bereaved families completed the planting of a tree of healing. later, at the corner of london bridge, there was a minute's silence. there were floral tributes from some of those injured, including pc wayne marks, who was stabbed in the head and body as he took on the three attackers. this evening, as the actual hour of the outrage approaches, there will be more informal

gatherings of the survivors and those who lost so much on that night, 12 months ago. italy's new interior minister says he's determined to combat illegal migration. matteo salvini from the far—right league party, who's also deputy prime minister, was speaking on a visit to sicily. sicily is one of the main landing points for refugees from africa and the middle east. mr salvini said the country shouldn't be ‘the refugee camp of europe' and promised to stop new arrivals and expel people already in italy: translation: the best way to save lives is to prevent people from getting into votes. i will work with european partners in african countries to prevent thousands of desperate people from having the illusion that in italy, there are homes and jobs for everyone. there aren't even an homes and jobs for

all italians, let alone half of the african continent. let's take a look at some of the other stories making the news... the bodies of 46 migrants have been recovered after their boat capsized off the coast of tunisia. the defence ministry says 68 were rescued off svax province. tunisia is a departure point for migrants heading to italy. another nine people died, after a speedboat carrying refugees sank off the southern coast of turkey. early partial results in parliamentary elections in slovenia suggest a strong lead for the anti—immigrant sds party led by the former prime minister. a centre—left party led by a comedian turned politician came second. a hotel on the svaalbar archipelago off the coast of norway had an unexpected visitor, when a polar bear broke into a storage room through a garage door. the bear became frightened when a helicopter arrived carrying rescuers. it managed to escape through a small window. singapore is getting ready

to host the on/off summit between president trump and north korea's kim jong—un in singapore. but while it is currently definitely on — there is still some wrangling to be done. according to some reports, the north korean leader wants to stay in the presidential suite of a hotel, at the cost of 6,000 dollars a night — and his country say they can't pay the bill. now america and singapore are working to resolve the issue. hazel smith is an expert on north korea and a professor of security and resilience at cra nfield university here in the uk — shejoins me now. expensive taste the north korean leader has, who will foot the bill? first of all you must put this in perspective, any place where the summit takes place is going to be at

somewhere expensive because they are the only places that can provide the security for the security services, to be certain, whether it's mr trump on kim, to be less at risk. that is the same with all world leaders whether it is mrs may in the uk or anybody else. it's going to be expensive and it is not to think it wouldn't be. in terms of who is paying, every time you have a summit which involves a poor country may maybe an organisation, i would imagine it's the same with the palestinian talks in norway some yea rs palestinian talks in norway some years ago, somebody is paying for the accommodation because these poor states don't have the sorts of resources that the states they are dealing with do, like the us. that isa simple dealing with do, like the us. that is a simple fact. north korea is one of the poorest countries in the world why any terms whatsoever,

whether gdp per capita or trade volumes or anything else. we know it's a poor state. the argument could be, maybe mr kim could get his own funds and paid himself, that's another argument altogether and maybe one that ought to be heard but in terms of the actual situation, this is such a standard discussion that there would be place in any summit between a poor state and a larger one, and in this case every single minute of this summit and the preparations, the on, off, has been monitored. in terms of looking at some sort of exceptionalism. in this case, it's just not exceptional. security issues are important and this is a poor country. they will be discussing the money to pay for it. i believe you spent almost two years living and working inside north

korea. explain to me what preparations you believe might be going on behind—the—scenes that.|j worked going on behind—the—scenes that.” worked for unicef, it was some time ago. i have worked on north korea we search for 30 years. one of the problems inside north korea is that the bureaucracy does not work very well. you can imagine in a country which is poor, which doesn't regularly have access in its offices and bureaucracies to computers, even to fax machines to telephones, communications that all fall between the various ministries, they have rivalries with each other, so compounding the question of policy. as well as the question of simple bureaucracy that does not work very well. that means there is a bandwidth issue. it's very difficult for them to concentrate at a high level on more than one big issue at a time. they will all be scurrying

around, all those that have experience at the top of working with the united states, and a small number have. then the mid—level bureaucrats who are not used to working with the outside world and don't have access to communications. very few of them have access to internet and phone line access to the outside world. for them to be communicating with singapore is going to be, even to discuss basic logistics, that will still be fraught with day—to—day problems. there will be these issues. they will get over them, because they have the political will at the centre in north korea, it looks like, from what we can see, to go ahead with it. you have a rundown bureaucracy which does not work very well. and lots of preparations to do. we must leave it there but thank you for your time. stay with us on bbc world news, still to come: after weeks of deadly unrest in nicaragua, pope francis calls for an end to the violence.

this is bbc world news today. the latest headlines: china has warned president trump over his decision to impose new trade tariffs — beijing says talks with washington could fail. a special service has been taking place in london — to remember the victims of the london bridge terror attacks one year on. eight people were killed when three men drove a van into pedestrians and then stabbed people at a nearby market. a siege has ended at a nicaraguan church where opposition supporters had sought refuge after being attacked by riot police and pro—government militias. some 30 people had taken shelter in the church of san miguel, in the city of masaya — south of the capital managua. more than 100 people have been killed in six weeks of clashes in nicaragua. protesters are calling for president ortega to step down. efforts by the church to mediate collapsed last week after several

bishops received death threats. pope francis has now called for an end to the violence. translation: ijoin my brothers, the bishops in nicaragua, in expressing my sorrow for the violence in the country with people killed and wounded by armed groups that are trying to repress social protests. i pray for the victims and their families. the church always pushes for dialogue but this requires a real effort to respect freedom and life. i pray for the end of all violence and for talks to be resumed as soon as possible. joining me now is kai thaler. he is a professor of global studies at the university of santa barbara. thank you for your time, let's rewind debates. the us how these protests began. —— remind us. they began about six weeks ago after the announcement by the government

of president daniel ortega and his party of social security reforms that would cut the rates of pensions and increase health care costs for retirees, and people currently in the states social security system. this initially sparked fairly small protests by university students and retirees. but these were quickly repressed by police and pro—government youth groups acting essentially as paramilitaries. this initial repression bred a strong response in the population and protests a nd response in the population and protests and mobilisation grew throughout the country as a government crackdown continued. the protests have been ongoing now throughout the last two months, and... developing very quickly as well, they seem to have progressed

rapidly? yes, they grew much more quickly than i think most observers of nicaragua would have expected. but there have been fluctuations, there have been periods where there have been less protests and less repression, so there was some hope when the catholic church led dialogue began, that there might be some progress, but with those talks breaking down and increased government repression, it's back to more intense protests and violence. i wanted to ask you about whether or not you think this could be the end of president ortega's leadership. this is his third term in power, i believe. could this be the end?” think it well could be. president ortega has lost many of his key supporters since coming into office in 2007. he has relied a great deal on support from the business community. and the top levels of the catholic church. that support has

110w catholic church. that support has now dissipated. this aura of invincibility that ortega had before has been broken. previously, protests against the government were fairly small. when repression occurred, there was little resista nce occurred, there was little resistance from protesters. now, university students and others have shown they are willing to fight back and stand up even in the face of deadly violence. it is a situation we will continue to watch. thank you, professor. all the sport. novak djokovic is through to the quarter—finals of the french open after a straight—sets victory over spain's fernando verdasco. the 31—year—old serb, seeded 20th, has reached the last eight at roland garros for a 12th time — an open era record. the 12—time grand slam champion will now play marco cecchinato in the last eight after the italian upset belgian eighth seed david goffin. elsewhere dominic thiem, alexander zverev and madison keys

wanting to talk to anybody and really, it was the feeling of wanting to be away from the world, actually. doctors say new research means thousands of women with the most common form of early stage breast cancer could be spared chemotherapy. trials of a genetic test have found that the treatment can be safely avoided without affecting outcomes. the test is carried out after surgery to see whether a tumour is likely to spread and people get a score out of 100. women who score 0—10 are considered low risk, and there is no benefit in having chemotherapy. at the other end of the scale, people who score over 26, there is a definite benefit. but there's a grey area for most patients, who are in between and it is that group which the trial was focusing on. the findings suggested that for those patients aged over 50 chemotherapy was not needed.

there has always been this uncertainty about what the best recommendation was for the two thirds of women who had a test in the mid range, and this trial definitively addresses that very important question. a leading breast cancer charity is calling for changes in cancer treatment. some clinicians will update their practise immediately, because the results of this study are so significant and that is why we want to see the clinical guidance updated so that more patients can benefit across the nhs. the trial is a step in trying to provide more tailored treatment for breast cancer patients. anisa kadri, bbc news. thanks for watching. there will be fewer thundery showers over the weekend. no sign of any rain from that cloud. temperatures
