a senior officialfrom the biden administration joins us to talk trade. and we explore a sponge city where more than 300 climate projects are running to guard against floods. hello and welcome to business today. i'm steve lai. it's day two of the democratic national convention in chicago and high on the agenda is trade. this is trade. comes as us presidential election this comes as us presidential election is being closely watched around the world. from trade tariffs to tensions with china, asian governments are closely watching the us presidential election for clues on who they'll be doing business with next year. enoh t ebong, was appointed by president biden. she is attending the dnc in her personal capacity — and gave us a take on what kamala harris brings. there has been a tremendous vision put forward for the first in terms of what the biden — harris has accomplished

by taking an economy that was flat on its back and really building it up to be the strongest economy in the world today. that will continue as has been unveiled by the vice presidents policy. she will continue to do that in the next few days. continue to do that in the next few da 5. ., ., continue to do that in the next few dam-— few days. inflation very much on the minds _ few days. inflation very much on the minds of _ few days. inflation very much on the minds of voters - few days. inflation very much on the minds of voters how. few days. inflation very much i on the minds of voters how does harrises plans contrast to trump�*s approach of what the republicans are pushing? i think it's a complete contrast in vision. this administration and a harris administration going forward if elected will look to the support of all american people. —— to be supportive. you can see by the policy initiatives that have been put out, an effort to make sure that all americans can live in the way that they should wish to. it's positive,

its front forward, is looking to the future and it's about all people, about our freedoms and again about the future. this has been set and this will continue going forward. when it comes to the region, japan counts as one of the biggest allies of the us. naomi fink, who's chief global strategist at nikko asset management gave us a sense of what to expect if harris wins the presidency. there are a few measures that are designed to help the middle class, such as a child tax deduction. and also some middle—class tax advantages there. i think that is supposed to be offset by higher corporate taxes, if i'm not mistaken. i think in general, what i would say is that the us, whoever is in power, it doesn't really have that much

room to engage in physical easing. whether it's room to engage in physical easing. whether its tax cuts or subsidies or spending, it's 120% debt to gdp, that something we have to remain conscious of. whoever the next president is they will have to deal with the debt ceiling discussion that was kicked down the road, the cameras kicked down the road until the next presidency. —— that can was kicked. if we do have a policy that offers relief for the middle class that probably does have to be offset with increases somewhere else. net— net, i don't think we will see in extremely communicative fiscal policy going forward. when it comes to the us as allies japan, and south korea as well, what do you read into harasses attitude towards trade with its allies? i harasses attitude towards trade with its allies?— with its allies? i think what we have — with its allies? i think what we have seen _ with its allies? i think what we have seen most - with its allies? i think whati we have seen most notably with its allies? i think what i we have seen most notably in the us but also worldwide is a

winding back of some of the globalisation that happened in the early to thousands. and some protectionism by the same token. so if we look at both parties policy we do see some evidence of protectionism on both sides. i think how the trade relations evolve will probably be dictated by how effective diplomacy is. if the relationship for example with china, which is the probably most contentious trade relationship can progress smoothly, even despite the less open environment, i guess we have right now, that's probably going to be good for the region. going to be good for the region. staying with the us, where there are more troubles for boeing. 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 737max jet shortly after takeoff>the bbc�*s michelle fleury has more from new york. boeing has grounded its entire test fleet of 737 x after a routine post flight ends pageant revealed damage to a crucial component that mounts the engine to the planes wings. boeing said in a statement... our team is replacing the part and capturing any learnings from the component and will resume flight testing when ready. it said it has informed its regulator, the federal aviation administration as well as its customers with the triple seven x, boeings largest and newest aircraft was due to go into service in 2020. it's been plagued by delays and cost overruns. that date was pushed back to 2025. now the discovery of a faulty engine part threatens to push the date back even further.

hey, i'm zoph with the catch up. tonight, spice found in vapes in schools, sober clubbing, and a very rare red squirrel. first... i was addicted to smoking spice vapes at school. that's what one 16—year—old has told us. an investigation by the uni of bath has found that school pupils have been unknowingly using vapes with spice in them. this is what happened to ben — we've changed his name to keep him anonymous. he first tried it at a mate's house when he was 1a, without realising what it was. him and his mum have spoken to us about the impact. literally every second of the day. were you doing it in class? yeah, i was bringing it to school like it was like in class. during lessons? yeah, obviously in lessons i was just not paying attention.

i was just too busy getting high. spice can cause dangerous side effects like dizziness, heart palpitations and psychosis, as well as being highly addictive. now, if you've been affected by these issues, you can find support at bbc action line. sober clubbing — do you think you might fancy it? well, there's been a big rise in the number of people choosing to cut down on or give up alcohol altogether. a recent yougov survey found that more than a third of 18 to 2a year olds are sober, and that means the demand for alcohol free social events is growing. like this night at ministry of sound in london. time now for 10s of squirrels as one's been spotted in east dunbartonshire, an area of scotland that they're not normally in. saving scotland's red squirrels said it was a really rare sighting as numbers of the species have fallen a lot. that is adorable. you're all caught up now. see you later.
