could canada's freight trains be about to grind to a halt? businesses across the country brace themselves as a labour dispute looms with the union that represents engineers, conductors and dispatchers. turning sour. beijing is launching a new anti—dumping investigation into european dairy imports, after the eu put additional levies on chinese evs. 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. iam mark i am mark lobel. we start with warnings that canada's economy faces devastating consequences if its freight trains stop moving in a few hours time. stop moving in a few hours�* time. severe supply chain disruptions of raw materials and finished products are expected if over 9,000 workers take part in labour stoppages at rail operators canadian national and canadian pacific kansas city.

this is the first time simultaneous stoppages may occur. joining me now is the president and ceo of the canadian federation of independent business, dan kelly. dan, you fear that if these freight trains ground to a halt, the economy will as well. how quickly do you think any disruption will be felt in canada and across the borders? euper canada and across the borders? super fast, in canada and across the borders? super fast. in fact. — canada and across the borders? super fast. in fact. in — canada and across the borders? super fast, in fact, in many— canada and across the borders? super fast, in fact, in many ways _ canada and across the borders? super fast, in fact, in many ways it - canada and across the borders? super fast, in fact, in many ways it is - fast, in fact, in many ways it is already here, some of the railways have had to stop shipments of hazardous or perishable goods in advance of the potential labour dispute, so we are seeing some signs of it now, but thatjust gets hugely worse in the coming hours if this job action does take place. you say our job action does take place. you say your organisation _ job action does take place. you say your organisation is _ job action does take place. you say your organisation is not _ job action does take place. you say your organisation is not siding - job action does take place. you say your organisation is not siding with | your organisation is not siding with either party, but you are calling on the government to basically force the government to basically force the workers to accept a deal. now, thatis the workers to accept a deal. now,

that is despite the fact they have reservations about how they are scheduled, how they are protected from fatigue and possibly relocated to other regions?— to other regions? look, i don't think it is _ to other regions? look, i don't think it is siding _ to other regions? look, i don't think it is siding with _ to other regions? look, i don't think it is siding with anyone, l to other regions? look, i don't l think it is siding with anyone, we are asking government to put the two parties into binding arbitration where a deal needs to be knocked together. canada has incredibly prounion labour laws, generally speaking, and our government has certainly been siding with the unions 99 times out of 100. but right now we need some action to take place so that the canadian economy is not put in jeopardy. we have all kinds of small businesses that are in desperate straits because so much, given our vast territory, is shipped by rail. two ears of territory, is shipped by rail. two years of railroad _ territory, is shipped by rail. two years of railroad strike was called off in america whenjoe biden intervened. do you suspect or have you heard anything from justin trudeau? do you think the government will heed your request? it is

trudeau? do you think the government will heed your request?— will heed your request? it is far from certain, _ will heed your request? it is far from certain, but _ will heed your request? it is far from certain, but i _ will heed your request? it is far from certain, but i am - will heed your request? it is far from certain, but i am not- will heed your request? it is far| from certain, but i am not super optimistic. 0f from certain, but i am not super optimistic. of course, the government is urging the parties to stay at the table and avoid the strike, as they should. but will they take any kind of decisive action in the intervening hours? i am not super optimistic. in fact, we have had some experience with this, we had a port strike not that long ago and the transportation infrastructure in canada ground to a halt then as well. of course, this is much more serious because it is our two major railways at the very same moment and it would affect goods coming into canada, notjust from overseas, but from coming into the us, as well of course as canadian exports, which are pretty critical to an economy like ours. 0k, critical to an economy like ours. ok, thanks very much forjoining us there, dan kelly. china is hitting back after the eu published new additional rates to be paid for electic vehicles manufactured in china and then imported into the eu. china says the new ev tarrifs

are unfair competition. the eu says the battery—powered cars are heavily subsidised. now china says it is opening its own investigation into suspected subsidies for eu dairy imports. so is china's probing of european yoghurt a surprise or is this tit for tat to be expected? that's a question i put to an expert on china's economic diplomacy, dr yujie. i'm kind of expecting this kind of tit—for—tat measures from beijing, because really, judging from the comments that the chinese minister of congress made earlier in the year, by saying that china's measures for a tit—for—tat against the ev tariffs would only be coming drip by drip. so i think this is probably the latest episode of this incoming trade war between beijing and brussels. and of course, the target in here, it is not the european union as a whole, but the targeting here is france

and germany. particularly france is the one that is behind the entire ev tariff, so i think that is the key reason. french yoghurt, then, may be the target, but if we look at engine motor cars, raw materials, they are all other areas that china could look at investigating or probing. but overall, the surplus is in the eu's favour. so is this a battle that china can win if they go down this path? well, this is a battle that china firstly can win, although on the other hand what china are looking to do here is which kind of european product that would not necessarily affect the everyday life of the chinese ordinary customers. so in the case of dairy products, because of the slowdown of the economy, because of the chinese consumers have less money, they are less likely to spend more on dairy products imported from the eu, so thatis products imported from the eu, so that is also a domestic economic reason that they are picked very carefully, not on other products, but on the dairy.

i want to take you over live to the pitch as the search and rescue operation going on nowjust off the coast of the italian island of sicily, where the two bodies have been recovered and another two have been recovered and another two have been located. 0f been recovered and another two have been located. of course, you will probably be very familiar that mike lynch, a british tech entrepreneur, is missing and his daughter, hannah. this is after a luxury yacht sank off the coast of the italian island off the coast of the italian island of sicily. many people now waiting to find out about those bodies that have been recovered. and the search and rescue operation, those are the latest pictures right now. we will bring you the latest here when we get any more information. from the search and rescue site there. so we will keep an eye on that for you. just before we go back to sicily,... 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. 0ur 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 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 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. let's go to the us now. the us added 818,000 fewerjobs than had been reported earlier, according to revised figures issued by the labor department. they cover the 12 months through to march and point to greater economic fragility. it also comes as several big retail names reported thir results. shares in big box store target

are up after the company snapped a streak of sales declines. price cuts led to more customer traffic in its shops. the picture wasn't so rosy at macy's. the department store chain reported another quarter of shrinking sales. meanwhile, the owner of tj maxx posted another quarter of sales growth and raised its profit forecast for the year. i'm nowjoined by our north america business correspondent michelle fleury. a mixed retail picture, vulnerability in thejobs market, resilient sales — what does this all say about the chances of a soft landing in the us? 0k, ok, i think the retail sales picture has been getting better. it is perhaps not as strong as people would like, but it also shows us shoppers are still spending and it continues to be a huge driver of economic activity, perhaps at a sort of reduced levels. then, of course, you add to that the bureau of labour

statistics revising what the actual jobs growth was by nearly 30% less than initially reported. 0n the face of it, that would seem like bad news, but given that it is talking about much earlier in the year, it is a backward —looking number, and so i think the scenario hasn't changed. what we have learnt today is that perhaps the federal reserve, as it contemplates what to do next in terms of interest rates, which are at a 22 year high, this gives them a bit of cover to move ahead with the anticipated rate cut in september. with the anticipated rate cut in september-— with the anticipated rate cut in setember. ~ . , september. michelle fleury in new york, september. michelle fleury in new york. thank— september. michelle fleury in new york. thank you — september. michelle fleury in new york, thank you very _ september. michelle fleury in new york, thank you very much. - september. michelle fleury in new york, thank you very much. that i york, thank you very much. that wraps up business today. you are up to date.

hello, i'm matthew amroliwala. welcome back to bbc news. let me take you back to sicily and the

latest details there in the ongoing search for the passengers who were on that yacht when it sank on monday. these scenes have seen quite a lot of activity over the last hour or hour and three quarters and you can see with the information on screen that four bodies have been found inside that sunken yacht. about 45 minutes ago, an hour ago we saw the body bags of the first couple of those bodies being brought to shore with the diving teams, the emergency teams and confirmation that two more bodies have been found now. we are still unclear if those bodies have been brought to shore as well. it is a very fluid situation and a very distressing situation in terms of that situation and what it has been like for the diving teams. we know of the huge challenges that they have been pacing over the last

few days, going down, 50
