this is business live from bbc news with maryam moshiri and sally bundock. a $16 billion ramping up of tensions — that's the amount the us is imposing on chinese goods — and beijing has responded in kind. live from london, that's our top story on thursday 23rd august. total tariffs imposed by both china and the us now total $100 billion — what can be done to ratchet back tensions before they further impact global trade? also in the programme. the brexit back—up plan — the uk government unveils its contingency preperations in the event there's no deal when britain leaves the eu. european markets have opened in positive territory. communication is key in so many industries but in the health service it can saves lives.

one app is improving how doctors and nurses are talking to one another — we'll find out how it could revolutionise health care. also, a penny for your thoughts — ditching 1p and 2p coins wouldn't cause inflation according to economists at the bank of england. do you want to keep coppers? are they outdated as we move towards a cashless society? let us know — just use the hashtag bbcbizlive. welcome to the programme. we start with the escalating trade war between the world's two biggest economies — because new taxes on billions of dollars of imports come into force today between the us and china. the us is slapping new tariffs on $16 billion worth of chinese imports.

china is responding in a tit—for—tat move — taxing us imports worth the same amount. hundreds of us products will face a 25% import tax in china — ranging from coal to cars. the us will tax hundreds of chinese goods at the same level — from trains to steam turbines. this takes the value of us and chinese goods caught up in the trade war — to total of $100 billion — piling pressure on exporting companies on both sides — and threatening to force up prices for consumers. the white house maintains it's the only way to tackle china's ‘unfair practices‘ in trade — and specifically its theft of us technology. beijing says it's being forced to react to washington's unreasonable actions. karishma vaswani — our asia business correspondent — is at the port in singapore. a very, very busy port where you

are, karishma, anybody there would be concerned about this. that's right, lots of businesses i have been speaking to over the last few months as this trade war has ratcheted up on both sides, very concerned about how long it will continue. today we have seen that $16 billion come into effect on either side, china's, is $16 billion come into effect on eitherside, china's, is minister has come out and said it believes the us is straying on the wrong path and all it can do is respond to the trump administration's actions, one of the things beijing is going to do asa of the things beijing is going to do as a result of this is played by the international trading rules, as it likes to call it, take the issue to the world trade organisation. this has to typically been china's

approach during this process. they say, we want to play by the rules but you aren't making this easy for us, so let's sit down, talk, negotiate and try and come to some sort of solution. in the meantime this is happening against the backdrop of further talks between the two sides. i've been told that on either side, beijing and washington, these were pretty low—level officials having these conversations, partly because neither side really expects much to come out of these talks. most economists and experts i talked to say nobody wins in the circumstances when it comes to a trade war. but who has the most to lose? well, sally, i think it would be fair to say both sides have a lot to lose and not just the say both sides have a lot to lose and notjust the us and china. 0ut here in the asia—pacific region we are kind of stuck in the middle, or caught in the crossfire if you will. i was talking to a company that makes speakers based here in singapore but also in its chinese factory they have just found out

that those speakers are on the list of the next target by the trump administration, that $200 billion worth of goods coming from china into the us. their biggest market is the united states. they are really concerned about how much more expense of their products going to be. as the business owner said to me we are sandwiched, our voices will drown out between these giants and privately lots of government officials in this part of the world also extremely perplexed. what they are worried about is that if this uncertainty, this trade war continues, companies stop setting up new companies, they stop hiring or creating new jobs, new companies, they stop hiring or creating newjobs, investment gets affected and then economic growth gets affected too. that's the big fear, sally, in this part of the world. thank you, karishma vaswani, pa rt world. thank you, karishma vaswani, part of our team in singapore. in a moment we'll get a view from the us on why some companies are pro—tariffs — but first some of the other day's stories. saudi arabia has denied reports it

has called off plans to sell shares in state oil giant aramco. in a statement it says the government remains committed to the ipo of the company at a when conditions are optimum. profits at qantas have surged despite a rise in the price of fuel. net profit at australia's national airline was up 15% to more than $700 million over the past year. aggressive restructuring has seen the airline slash jobs, reduce its fleet and cut loss—making routes. policy makers at the federal reserve are considering raising interest rates again soon, despite concerns over global trade disputes. the minutes from the us central bank's last meeting will add to expectations of another increase next month. the fed left rates unchanged in august after raising them twice this year. as promised, more on our top story 110w. many us companies are now sounding the alarm about what increased tariffs will do to their business. but some are backing the president's trade policy — especially those in industries that

have struggled against chinese competition as paul blake reports from cincinnati. trade wars are fought on factory floors and this assembly line outside of cincinnati, ohio has become a front line in the trade war 2018. sumerel tires remanufactu res some 70,000 tyres per year, sanding down their worn out edges and adding new treads. i've been doing this 5a years and this probably is, the last five have been the toughest. majewski says their business is being run over by cheap nonreusable tyres imported from east asia. the problem, he says, is that china is subsidising these low—cost imports, allowing them to be sold at the same price as his rebuilt tyres, and given the choice between a new or a refurbished tyre, consumers will go for the cheap import. so, what's the solution? he says tariffs. the low—cost tyres coming in are ruining our business so we want to see something happen so we're on a fair playing field.

majewski is so worried he took his concerns straight to the top. so what's this here? i wrote president trump. it says, "i will not tolerate unfair practises that harm american workers, farmers, ranchers and businesses." to many on the outside world donald trump's policies can sound like a trade—based temper tantrum. but for blue—collar workers in towns like cincinnati it's a us president standing up for their livelihoods. let's look at how the markets have been faring today, this thursday. this is what the stocks look like in asia, the nikkei is in positive territory. worries over this trade tensions between the us and china have had an impact, in particular on stocks in china and the hang seng. the dowjones stocks in china and the hang seng. the dow jones closing stocks in china and the hang seng. the dowjones closing on a low. european stocks opened around a0 minutes ago. it is a bit of a mixed picture but europe retaking a lead

from asia, some european stocks, the dax just about lower, but they are managing to stay in positive territory. it is a big day here in the uk for brexit because in a few hours' time we are expecting a speech from brexit secretary dominic raab on what would happen in the event of a no deal. 0ur economics editor kamal ahmed is following events in the newsroom — tell us more on what we'll be hearing later. he is going say that although he believes a deal is still the best possibility and the leading possibility and the leading possibility as britain leaves the european union, it is only right, he will say, that britain prepares for no deal. the government in the uk has always been clear that no deal, it says, is better than a bad deal evenif it says, is better than a bad deal even if no deal, as many economists suggest, could have a very negative effect on the uk economy. today the

government is going to show, or try to show that the no deal scenario is credible, it's going to stop publishing documents on different sectors of the uk economy —— start publishing. showing what preparations are being made for no deal, no deal would mean britain reverts to world trade organisation rules like any other third country with no free trade deal with the eu such as america, for example. and show how this preparations are progressing. 0f show how this preparations are progressing. of course, britain has been a member of the european union for many decades so things like safety regulations, supply chains incredibly interwoven. untangling thoseif incredibly interwoven. untangling those if there is no kind of deal has been described as trying to remove an egg from an omelette, so very complicated. but we are going to see if things like the pharmaceutical industry, financial services, farming, how all of those sectors will be affected if there is no deal. kamalahmed, thank sectors will be affected if there is no deal. kamal ahmed, thank you very

indeed, economics editor. removing an egg from an omelette? many might say we have scrambled egg on the menu at the moment! laughter ana cuddeford is investment director at m&g. welcome. we were all listening to kamal ahmed and it's a very significant day in this brexit saga. at how helpful is it, do you think, for businesses or individuals to have this kind of go to document to tell them what to do if there isn't a deal? i think the government has to do something. clearly as we know from financial markets' perspective people don't like uncertainty. markets don't like uncertainty so it isa markets don't like uncertainty so it is a good thing there is some kind of guidance out there. the focus is on the fact we still don't know what is going to happen so a lot of these trade talks and sort of negotiations quite often don't come about until right at the very last moment. there isa right at the very last moment. there is a lot of brinksmanship and it is absolutely necessary to be prepared, but at the same time i think we have

to continue to watch developments. let's talk about the fed because we had the minutes from the latest meeting from the us federal reserve, central bank, the world's biggest economy, what they say affects all of us. what were the main points from that meeting? two things really, one is that the us economy is in good shape. it is strong and they will continue to raise interest rates. now, that is a good thing. don't forget we are at very low interest rate levels and we are getting back to normalisation. the fa ct getting back to normalisation. the fact that the economy continues to grow as we expect it to is a good thing. the second thing that i think is quite important following your trade talks is that they are yet to see any of the companies in the us cutting back spending or doing anything to counteract those trade spats we are seeing. that's encouraging, isn't it? i guess the minute the central bank in the us

sees the impact of trade tariffs, companies cutting back on expenditure or reducing employment levels or anything like that it is a real red flag for them. yes, and some of the figures you mentioned earlier are very scary but at the same time we have to put into context this is a drop in the ocean to some of these economies and what we are looking for is will present trump pose further kind of tariffs, and then also to your point, sally, we have the jackson hole meeting on friday which is policymakers and they will be able to give us a lot more detail on what is going on in the economy is. thank you very much indeed. that meeting is of the us federal reserve and all of the team at the central bank in the states and we will tell you what happens at that meeting at jackson hole. still to come. a potentially life—saving app, literally. it's helping health care practictioners communicate with one another — freeing them up to spend more time with patients — we'll meet the man who came up

with the idea. you're with business live from bbc news. have you had a pay rise this summer? don't say a word! if you have you're lucky, as the average pay rise awarded by british employers weakened during the three months to july for the first time in nearly two years. sheila attwood is from xperthr who compiled the data. she isjoining us now. sheila, these results tally with other recent signs of weak wage growth don't they? they do, yes, but there is a couple of reasons not to be disheartened by these figures. we had a long period of very subdued pay rises following the recession and they bumped up to about 2.5% at the beginning of this year, so we have only dropped back 0.2%, so it is a small blip but there are still what is of employers awarding high awards than last year and the proportion of deals worth

more than 3% hasn't changed, it is still a quarter of deals above 3% so if you got more than 3% then you are doing quite well still. is there a difference in what you see in different areas, in different sectors, in terms of whether people are getting bigger pay awards? the construction sector is doing well, the chemical sector, high rewards in the chemical sector, high rewards in the utilities sector following low awards in the past few years in that sector. some of the lower paying industries are affected by the national minimum wage and the national living wage and we had increases in excess of a% in those two measures, so some of those employees by virtue of being on those very low rates would have got some higher increases this year. sheila, the reasons why? employers tell us that what they look at is the local labour market and what they can afford to pay. with the labour it is very tight at the moment, there is lots of recruitment and retention issues, they have to look at what local employers are paying, what other employers in

their industry are paying and then they work out what they are going to have to pay in order to secure the staff they need. 0k, sheila, thank you very much indeed forjoining us. really interesting story on the business life page, what team bonding activities have you been forced to endure. please get in touch, #bbc business life. your‘re watching business live — our top story — new us — china tariffs come into force today — both sides slap import duties on $16 billion worth of one another‘s goods. now, communication is key in any workplace — but potentially no more so than in hospitals and clinics. we're all used to using messaging apps — an estimated 2.a8 billion people globally will be using them around the world by 2021. and businesses are increasingly turning to them to enhance communication between employees.

forward is an app now used by 2,000 national health service clinicians — it's an app specifically developed for the health care sector. and its creators claim it saves health care workers up to one hour every working day. you can imagine the pressure on uk health care workers, it is very valuable. dr barney gilbert is chief executive of forward. it was his big idea. welcome. doctor is key because you are a doctor and have worked in the health service for quite some time and that is where you came up with the idea? absolutely. my story was i was a hospital porter before going to medical school and being a poor tel abyad to understand how a hospital works and that is where i first saw this rubble of broken communication. i went to medical school, came back

into the system as an nhs doctor and ten or more years on and realise nobody had solved the problem and somebody had to. what were we doing? we were using pagers, these brick like devices that sit in our pockets and feel terrifying, they are a chaotic and impersonal way of communicating. some people started using whatsapp which is not a secure way of communicating with people around you and also not the right way to do it because if you are working in a hospital or in health ca re working in a hospital or in health care more broadly you need to find who you need, you need to be in great detail communication with these people, so we found a way of building an early product with some other doctors and coders and called it forward and we thought, let's champion this in the grass roots of the nhs and get a body of people behind it. you mentioned whatsapp. i know that many medics use an app where they can communicate with each other medex note, what is it you are offering that is not out there

already? the truth is that at the start our products and there are various other people in the space, they were quite similar, we were looking to build a secure whatsapp type product and ours has evolved way beyond that because we saw the value we were given to doctors, nurses, pharmacists, physios using forward was not just nurses, pharmacists, physios using forward was notjust in the hospital but across the walls and outside the walls of the hospital in the community. using our product in really intricate ways to feed the right information to the right person allows it to create real additional value beyond just being a secure messenger. you have additional value beyond just being a secure messenger. you have explained that in some hospitals around the uk they have just taken this on board themselves, it is not something you have communicated to them, they have just got on with it and championship within their own nhs trust and now as part of that particular nhs trust but to what extent will it go beyond there? one of the frustrations many of us hear about is the technology available, the nhs by nature is slow

to react for lots of different reasons and lack of money is a key one. absolutely. from the outset we built this as a grassroots product, this is for doctors, nurses and eve ryo ne this is for doctors, nurses and everyone else working in the nhs right across the system. they can download it on an app store and start right away. at some point we need to talk to the management of the hospital and people in a community setting but for people who love what they are doing and can't do theirjobs love what they are doing and can't do their jobs without love what they are doing and can't do theirjobs without it it is going to work regardless of the kind of bureaucratic steps beyond that. where do you want to take this? where do you want to take this? where do you want to take this? where do you want to take forward in the future? the dream is we change health care communication around the world, we are starting in the uk because it's a system myself and my collea g u es because it's a system myself and my colleagues know really well. we know that if we can find that scale in the nhs we can take it elsewhere. for it to work more people need to have it. if you want to be getting in touch with people on the other side of the country you would need them to have it as well. how will get that exposure? there are various

ways we can get that network kind of effect. that's right, people need to feel like they are on a product that is valuable from the moment they come on because everyone they might need is on it and we are doing well at that. the way to do it is to find hubs of excellence, for example, leedsis hubs of excellence, for example, leeds is a brilliant place in yorkshire, where some midwives in the community started using forward, they told other people in the hospital as started spreading the use of the app and now it is used outside the walls of the hospital. if you are knocked down by a bus in leeds or manchester this afternoon from the moment the paramedics come to collect you to deliver you to the a and to collect you to deliver you to the aande to collect you to deliver you to the a and e department throughout your journey at the hospital and afterwards when the physio is seeing you in the community, the gp is given new painkillers, that can all be communicated and passed forward. this has been quite a mammoth task for you because you trained as a doctor, lita months ago did you stop working as a dr but at the same time

you created this company and have been running this company is well. you've been busy! it has been a busy time. you are extremely energetic and passionate despite that, i'd be on my knees! there is an emerging wave of doctor entrepreneurs and the reason for that is there are lots of problems to fix and the doctors and nurses and others in the system other people to fix these problems. it was a busy period for me but worth it because the two feed into each other, seeing this problem and minute and minute by minute on a shift as a doctor gives me the extra motivation to solve it. will you miss being a doctor?” motivation to solve it. will you miss being a doctor? i think i will, so far it's been too busy to notice but i think i will in due course. thank you for coming on. in a moment we'll take a look through the business pages but first here's a quick reminder of how to get in touch with us. stay up—to—date with all the day's business news as it happens on the bbc‘s business live page, business and analysis from our team of editors around the globe and we want to hear from you.

a.99 level is important so we have to ta ke a.99 level is important so we have to take careful consideration. what about this argument that it won't cause inflation if we removed copper? many say naturally shops will just round—up, they copper? many say naturally shops willjust round—up, they won't round down. there is a danger of that but all of the economic studies say it would be negligible, so it would be a minor rise in prices. i like using copper coins. i think it's important to have. the important thing is to have choice. yes, cashless is the way forward. it is expensive to churn them out. yes but people have to have the choice of having them both, not eve ryo ne choice of having them both, not everyone will want to go cashless. my everyone will want to go cashless. my parents, my dad would want to still use coins. we have had so many tweets on this, let me read a few. we have had a tweet from gavin his says, get rid of them for good, they collect everywhere all year, they go toa collect everywhere all year, they go to a charity in our house. what's wrong with them going to a charity,

gavin! arendt said we did it in canada and we suffered no ill effects. barbara peters says they are pretty use force, i'm trying to give retailers might coppers to pay for stuff and they are trying to give them back —— pretty useless. many view are for getting rid of anything below 5p, somebody says get rid of the ten p. injapan we the ten p. in japan we still the ten p. injapan we still have 1 yen. what do you think? i'm with most of the public. get rid of the cheque-books before getting the 1p and two p. that is a different argument, sally! thank you for talking to us. that's it from business live today. we will be back throughout the day with business news on both channels. bye— bye. with business news on both channels. bye—bye. goodbye. hello. temperatures yesterday got up

to 27 celsius in lincolnshire and we're not going to see a temperature like that for a good while because is turning much fresher today for all of us. there will be a mixture of sunshine and showers. the fresher and cooler air is filtering in, look at the yellow being replaced by these blues, the aircoming all the being replaced by these blues, the air coming all the way from the arctic. are much coolerfield air coming all the way from the arctic. are much cooler field to things, much fresher in northern and western areas this warning, a few showers across scotland, northern ireland, north—west england and wales, early morning rain in the south—east of england will clear and then we are looking at sunny spells developing. a bit of sunshine for eastern parts of scotland, those temperatures down on yesterday. 16-23d. temperatures down on yesterday. 16—23d. tonight we will continue with showers, particularly across scotland, northern ireland into north—western areas of england but

with lengthy clear spells it is gunned to be a much cooler night compared to recent nights, much more co mforta ble compared to recent nights, much more comfortable for sleeping, we have lost the humidity. in rural areas in the north the temperatures could get down into fairly low single figures. during friday we continue with showers across scotland, northern ireland into north—west england and across wales, some sunny spells elsewhere particularly the further south and east you are across the uk. but it's going to feel much cooler, look at the greens on the temperature map. much cooler weather, we have lost the oranges and reds. at best we're looking at 14, and reds. at best we're looking at 1a, 15 degrees in scotland and northern ireland, 15—19d across england and wales. these temperatures are below the average for the time of year. through friday and into the weekend we have had that north—westerly wind. ridge of high pressure on saturday but by the weather system will start spreading in from the west. let's start with saturday, probably the best day of

the weekend. lengthy spells of sunshine, dry day for most of us, just a few showers dotted around here and there. still on the cool side, temperatures 16—20d but perhaps with more sunshine around it may feel a little more compared to friday. into sunday we will see some cloud increase and rain spreading into the west as temperatures again on the cooler side. on monday they will rise up a bit, still quite a bit of cloud but it should be largely dry on bank holiday monday. that's all from me. goodbye. hello, it's nine o'clock, i'm matt barbet, welcome to the programme. while i am sure a positive agreement can be reached, i am equally clear that no dealfor can be reached, i am equally clear that no deal for britain is better than a bad dealfor britain. for months this is what prime minister theresa may has been saying, that leaving the eu in just over six months‘ time without any deal might end up being the best

option for britain. today brexit secretary dominic raab will release the first papers outlining the government‘s assessment of what the actual impact of leaving without a deal could be. we‘ll look at what a no—deal brexit might mean for you. also, hundreds of thousands of teenagers in england are getting their gcse results today, finding out how they did in a tougher, revised gcse exam system. most subjects are now being graded from nine to one. but what grade will students and teachers give the new system?
