a fresh blow for boeing — it's grounded its entire test fleet of 777x aircraft, after discovering a problem with a crucial component. beijing is launching a new anti—dumping investigation into european dairy imports, after the eu put additional levies on chinese evs. the world's biggest chipmaker, tsmc, breaks new ground on its first european plant in the city of dresden. plus, holding back the floodwaters — we head to copenhagen where hundreds of projects are underway to soak up or carry away heavy rainfall. welcome to business today. there are more troubles for boeing. how many times have we said that recently? the plane maker said its long delayed 777x jetliner has encountered a problem, forcing the company to ground it. this is the latest blow to boeing's reputation for quality after two deadly crashes and after an exit

door blew off a 737 max jet shortly after takeoff in january. michelle fleury tells us more. boeing has grounded its entire test fleet of 777x jetliners. the decision was taken after a routine postflight inspection revealed damage to a crucial component that mounts the engine to the plane's wings. boeing said in a statement... it said it has informed its regulator, the federal aviation administration, as well as its customers. the 777x, boeing's newest and largest aircraft, was due to go into service in 2020, but it's been plagued by delays and cost overruns, and that date was pushed back to 2025. now the discovery of a faulty engine part threatens to push the date back, well, even further.

china has hit back a day after the eu published new additional rates to be paid for electic vehicles manufactured in china and then imported into the eu. as we've been reporting, china is furious about the new ev tarrifs. calling them unfair competition. but the eu says the battery powered cars are heavily subsidised. now china says it is opening its own investigation into eu dairy imports. chinese officials say they have received complaints from domestic chinese manufacturers over european subsidies. so what's really going on? joining me now is an expert on china's economic diplomacy, a senior research fellow at chathman house, dr yu jie. first it was pork and spirits. now the chinese are probing european yoghurt. were you expecting this tit—for—tat and is that what this is?

tit-for-tat and is that what this is? . �* ~' ., tit-for-tat and is that what this is? . �* ~ ., ,. tit-for-tat and is that what this is?,�* , ,. , is? yeah, i'm kind of expecting this kind of tit-for-tat _ is? yeah, i'm kind of expecting this kind of tit-for-tat measures - is? yeah, i'm kind of expecting this kind of tit-for-tat measures from i kind of tit—for—tat measures from beijing becausejudging kind of tit—for—tat measures from beijing because judging from the comments that the chinese minister of commerce made earlier in the year, that chinese measures for tit—for—tat against ev tariffs are coming drip by drip. this is the latest episode in this burgeoning trade war between beijing and brussels will stop the target here is not the european union as a whole but the target here is france and germany, particularly france is the one with the higher ev tariffs and i think that's the key reason. french ouhurt think that's the key reason. french yoghurt may _ think that's the key reason. french yoghurt may be — think that's the key reason. french yoghurt may be the _ think that's the key reason. french yoghurt may be the target - think that's the key reason. french yoghurt may be the target but - think that's the key reason. french yoghurt may be the target but if i think that's the key reason. french | yoghurt may be the target but if we look at engine motorcars, raw materials, these are areas of china could look at investigating probing. but overall the surpluses in the eu's favour so is this battle china can win if they go down this path?

it's a battle china firstly can win. it's a battle china firstly can win. i think what china are looking at here is which european products that will not necessarily affect everyday life of the chinese customers, so in the case of dairy products, because of the slowdown in the chinese economy and because chinese consumers have less money, consumers are likely to spend less on dairy products imported from europe. that's a domestic economic reason that they have picked carefully, not on other products but on dairy products. on other products but on dairy roducts. ., , on other products but on dairy predate— on other products but on dairy roducts. . , , , ., products. ultimately this is over the diapute _ products. ultimately this is over the dispute on _ products. ultimately this is over the dispute on electric- products. ultimately this is over the dispute on electric vehiclesl products. ultimately this is over i the dispute on electric vehicles was that we have heard tesla have received the news that chinese made cars of theirs will receive 9% duty on top of the 10% standard duty applied on all imported cars from china, electric vehicles. but china is appealing to the world trade organization on this. how do you see this part of the dispute ending? ida this part of the dispute ending? iir: one would know how the dispute will end, at the end of the day, but what

see it beginning to incline more and more to resolve through multilateral institutions, hence the wto and dealing with the european union bilaterally. so we see i'm trying to certain coercive measures, not through the bilateral measures but through the bilateral measures but through the bilateral measures but through the multilateral institutions, and that's something quite new to me.— institutions, and that's something quite new to me. doctor, thank you so much, quite new to me. doctor, thank you so much. this— quite new to me. doctor, thank you so much, this will— quite new to me. doctor, thank you so much, this will rumble _ quite new to me. doctor, thank you so much, this will rumble on - quite new to me. doctor, thank you so much, this will rumble on so - quite new to me. doctor, thank you so much, this will rumble on so i'm| so much, this will rumble on so i'm hoping we will see you soon. to europe now. the european commission president has joined the german chancellor and the chief executive of the taiwanese semiconductor giant tsmc on tuesday to inaugurate a massive new chip plant in dresden. when built, the plant will be the first in europe for tsmc. will be the first it is teaming up with european chipmakers infineon, bosch and nxp. it will be known as esmc with the eu firms each having a 10 percent stake and tsmc holding 70 percent. the eu has approved e5 billion euros in german state aid for the project.

ursula von der leyen hailed it as a "win—win for all of us" here's david waddell. 3, 2, i, shovel. here's the breaking—ground ceremony in the german city of dresden for the world's newest semiconductor plant — the european semiconductor manufacturing company. but the world's biggest chip company, tsmc — that's the taiwan semiconductor manufacturing company — will have a 70% majority share in the new enterprise. the benefits to tsmc are clear. we choose dresden because of the reason, simple — it's very close to our customer. and also we can access many talented people. so we promise that we are going to continue to recruit and develop the talented people in this area. this is not tsmc�*s first foray

onto foreign shores. in recent years, it's been ramping up investment in arizona to bring some of its most advanced technologies to the united states. that has not been free of challenge. tsmc�*s warned the cost of construction of buildings and facilities there was up to five times what an identical plant would cost in taiwan, and that us talent was insufficient. taiwanese workers would need to be loaned in for a period. so, why germany? well, the auto industry here is the powerhouse of european manufacturing, and it has a challenge on its hands. the big german producers, volkswagen, daimlerand bmw, and other european marques, need to transition quicker to produce more electric vehicles. they're highly reliant on the right semiconductors and also on security of supply. european industries will benefit from more reliable supply chains and local supply chains, and new products that are tailored to their needs.

and, at a time of growing geopolitical tensions, tsmc will also benefit from geographic diversification to europe, better access to our european strength, like automotive — as you said, the customers are of importance for you — and to our unique single market. these chips are crucial to the global supply chain, today and in the future. president von der leyen mentions growing political tensions — taiwan exists under an ever—present threat. china considers the island an integral part of its national territory, while taiwan's far from ready to reunify with china. but the tensions reverberate far beyond taiwan — far beyond taiwan's shores — western governments are mindful of their industry's acute reliance on taiwanese chips. the consequences of escalating tensions could throw all sorts of industries into disarray and cast the global economy into meltdown.

david waddell, bbc news. let's head over to the danish capital copenhagen now. a huge effort is underway there to protect the city from floods and severe weather. more than 300 climate adaptation projects are in the works. including underground tunnels to carry away heavy rainfall. as well as the creation of new green spaces that act like "sponges" to help hold back water. our correspondent in copenhagen adrienne murray has been taking a closer look. a huge tunnel burrowing right under the city. 20 metres below ground. this is likejules verne, journey to the centre of the earth. it's part of a plan to protect copenhagen from flash flooding during heavy downpours called cloudbursts. acting as a man—made river, this is one of two tunnels that will hold large volumes of water, then carry it away to the sea.

this one runs down to the harbour. it's a 700 metres long and basically the two tunnels together should contain or retain 10,000 cubic metres of water during a storm event. in 2011, a once—in—a—thousand—year flood left the danish capital knee deep in water and caused widespread damage. now more than $2 billion is being spent flood proofing the city. it's very expensive to protect the city but you could say it's even more expensive not to. in 50,100 years' time, we will probably in copenhagen sees we will probably in copenhagen see some 40% or 50% more rain in a year. it's about these extreme events where all of a sudden we have a lot of heavy rain in a very short period of time, and theyjust become more frequent with the climate change. built up with impervious tarmac and concrete, many other cities have also been hit by flash floods. worldwide, the economic losses from flooding top

$100 billion a year. and within the next three decades that's expected to climb steeply. yet many cities remain underprepared. with more than 300 projects in the works, copenhagen is remodelling itself. this was once a congested roundabout, but hundreds of trees have now been planted, transforming it into a small woodland. creating green spaces like this one that can act as a sponge, help urban areas handle heavy downpours of rain. and when needed, this rather clever city park turns into a reservoir, holding back water from the nearby neighbourhood. we have a pipe underground where we can store the everyday rain. it's reused for irrigation of trees round in the park and in the neighbourhood. there is underground water storage,

and these walls can be closed off. it can fill the whole park up, actually holding back more than 20,000 cubic metres of water. take a look at this sunken sports pitch. it has a hidden purpose. this is actually used for storing rainwater during heavy downpours. then, this is filled with water. but low—lying copenhagen also has other risks to prepare for. we look into a future with a changing climate, we will have raising sea levels, we will have a warmer city, more heatwaves in summertime. and what we can choose is we can make the city more green, have more trees in the city. with more extreme weather expected in the decades ahead, denmark's capital is getting ready. and other cities are taking note. adrienne murray, bbc news, copenhagen. some light at the end of the tunnel for some of denmark's flood problems. stay with us on bbc news.

hello from the bbc sport centre. i'm molly stephens. now, the first test between england and sri lanka at old trafford is underway. ollie pope captains the side for the first time, with ben stokes ending a streak of 32 straight tests due to a hamstring injury suffered in the hundred. sri lanka won the toss and are batting first. they're1ii—3. we'll keep you up to date with the latest throughout the day. the men's tennis world number one jannik sinner has escaped a drugs ban after failing two tests back in march. the australian open champion — who lifted the cincinnati open trophyjust a day before the decision was announced — was found with traces of an anabolic steroid which can build muscle mass in his system, but avoided a suspension after successfully appealing.
