between the world's two economic heavyweights. chinese foreign minister wang yi is in washington — he's been meeting us secretary of state antony blinken and is expected to meet national security adviser jake sullivan. blinken told the un security council on tuesday he would work with the chinese foreign minister to prevent the middle east conflict from spreading. but talks with china are also expected to focus on trying to resolve disagreements over other issues — including trade. earlier this week, beijing restricted the exports of graphite — which is used in many products, including electric cars. china produces 90% of the world's graphite supply. the us responded by advising its top tech firms — which included nvidia — to stop exporting some of their latest ai products to china. soaring demand for nvidia's chips has driven its share price up by more than 200% over the past year, with china its leading buyer. janet mui is head of market analysis at rbc brewin dolphin. thank you for being with us. this meeting, coming at a time it seems the relationship is getting even worse. what can it achieve?

and with his time he was waffling, stammering, going back—and—forth, a bit evasive. that irked notjust a prosecution, but thejudge, who said irked notjust a prosecution, but the judge, who said the defendant has an interesting way of answering questions. we will see today what happens when he has brought back to court. ., ~ happens when he has brought back to court. . ~ ,, happens when he has brought back to court. ., ~' ,, , happens when he has brought back to court. . ~ ,, , . happens when he has brought back to court. ., ~ ,, , . ., court. thank you very much for “oininu court. thank you very much for joining this- — it's exactly a year since elon musk bought the social media platform once known as twitter. and a lot has changed, the name for a start, it's now called x. thousands of staff who were tasked with keeping hate speech and misinformation in check have been fired. so—called verified users now pay for their blue ticks, although it allowed anyone to simply buy verification for high—profile names that weren't theirs. it's lost nearly half of its advertising revenue, according to several analytics firms. james clayton reports from x's home in san fransisco. a year ago, elon musk famously, infamously, walked into twitter holding a sink. let that sink in, he quipped, before firing huge swathes of its staff. 30 seconds left. 35 seconds. everybody here? we're all about to get fired. it was emblematic of his erratic leadership. he slept in the office, changed twitter�*s name to x, talked about fighting mark zuckerberg, who launched a rival to twitter, called threads, over the summer. i got a taste of that unpredictability when i messaged him to ask him for an interview six months ago. a few hours later, he was telling me he'd appointed his dog to run twitter. i'm not the ceo of twitter. my dog is the ceo of twitter. 0k. but although some have left the platform, it has been remarkably resilient. a year on, x, formerly known as twitter, still exists. threads, mark zuckerberg's rival, has not been the twitter killer that some have touted it to be, but it still has major problems. despite what elon musk says, independent analysts say that twitter�*s user numbers are falling. x has put out different numbers, saying that things are going great — that there must be something going on that we're not seeing. but, basically, everything is down on a year over year basis. advertisers have also shunned the platform and the eu has criticised it for high levels of disinformation. he hired former advertising exec linda yaccarino over the summer to try to bring them back. many of you in this room know me and you know i pride myself on my work ethic. but, buddy, i met my match. but some investors say advertisers won't come back until the platform is better moderated. i think that twitter is dying. i think it's just dying right now. and i don't think twitter users like me want it to die because it's become such a valuable resource for me. but... but it's time. so i don't care what elon says. it doesn't matter what he says. there's a reality and there's a fantasy. the fantasy that ross garber is referring to is mr musk�*s big dreams for x. this is what he told me he wants x to become. if twitter�*s an accelerant to x... what does that... what does that mean? well, i guess you'll have to stay tuned to find out. ah, come on. we now know a little bit more. he wants x to do streaming games, video calls, banking, you name it — the everything app. that was embarrassing — almost died. but, ultimately, x still gets the vast majority of its revenue through advertising. if it's going to survive in the short term at least, it needs to bring them back. james clayton, bbc news, san francisco. in other news... the british airways owner iag has posted record profits of $1.8 billion forjuly to september. the airline group, which also includes iberia, vueling and aer lingus, said it boosted capacity by almost 18% with the delivery of 20 new aircraft. iag says its forward bookings are looking good, but that it's mindful that economic and geopolitical uncertainties could affect the rest of this year. us chip—maker intel reported results that beat wall street expectations for the july to september quarter. despite its overall revenue declining about 8% the same period a year ago, shares rose about 6% in late trading. the company also said it is on track to catch up with chipmaking rival tsmc in an increasingly competitive industry. american car—maker ford also reported its earnings. but unlike intel, it missed analysts expectations and saw shares falling about 3% in after—hours trading. the us auto sector is also in a state of flux — with ongoing worker strikes that have lasted six weeks, demanding fair pay and better benefits. the company said the strikes will likely reflect in the results for the next quarter. stay in touch with the @bbcbusiness team and me on socials, i'm @tadthnright. rhianna managers the council save garden herbs where social services, police, education and health come together for calls expressing concern about children. she with colleagues have to ensure their responses are safe and appropriate. i love myjob, i want to do a good job. it is not lost on me the sense of responsibility that comes with being a group manager. ibibic of responsibility that comes with being a group manager. bbc wales research shows _ being a group manager. bbc wales research shows that _ being a group manager. bbc wales research shows that responsibility. research shows that responsibility has increased across wales. the number of contacts into children services increased in all but three of 20 councils compared with last year. of 20 councils compared with last ear. ~ ., �* of 20 councils compared with last ear. . . �* ., ., ., of 20 councils compared with last ear. . . �* . ., ., ., of 20 councils compared with last ear. . . �* ., ., ., ., year. what we've had to do as a local authority _ year. what we've had to do as a local authority is _ year. what we've had to do as a local authority is significantly i local authority is significantly increase our workforce, particularly increase our workforce, particularly in the front door and into our locality teams.— in the front door and into our locality teams. that comes at a cost. bridgend's _ locality teams. that comes at a cost. bridgend's children - locality teams. that comes at a l cost. bridgend's children services overspent by £7.5 million this year. the deputy ministerfor overspent by £7.5 million this year. the deputy minister for social services met councillors to hear their concerns about pressures. the welsh government added they will continue to work closely with partners on the challenges services face. hello from the bbc sport centre. let's start with the cricket world cup, where we've reached the business end of the group stages. pakistan are hoping to rescue their campaign as they take on south africa — who could go top of the table with a win. pakistan won the toss in chennai, chose to bat and finished on 270 all out, babar azam and saud shakeel with 50s to get them to a decent score. south africa have begun their chase and are currently 74—2. pakistan realistically need to win all of their remaining games to have a chance at reaching the semi—finals. from one world cup to another. the final of the rugby union world cup is tomorrow between south africa and new zealand — while, the bronze medal match
