it's midnight in london, 8am in singapore and also 8am in shenzen where the chinese telecom giant huawei is expected to announce legal action against the us government for barring american companies from using its technology. now, a big announcement like that would allow huawei to seize back the narrative from the extradition hearing against its chief financial officer meng wanzhou, in canada. ms meng has made a brief first appearance at a court in vancouver. let's cross live to our china correspondent, stephen mcdonell. good to have you with us. how significant is this latest development? well, i think it is pretty, pretty significant because later today in since then we will hear from huawei and they will be arguing that there has been a

violation of meng wanzhou's writes —— in shenzen, we heard in court today, the lawyer for meng wanzhou, i would readers quote" there are issues arising from the treatment of meng wanzhou upon her arrival at vancouver international airport, her detention in subsequent arrest." what their going to be arguing in a separate case, suing, demanding the government, rates been violated, she was let to believe she was being investigated about one thing but clearly it was another. what she has ended up being arrested for was this extradition request from the united states. us government is arguing that meng wanzhou and huawei general deliberately conspired to lie to banks in the united states in order to get around the sanctions on iran. but in that hearing, which was only a brief appearance today, in

vancouver, her lawyer has also argued that this is political in nature and mention comments on the president, donald trump, where he would consider letting meng wanzhou go if it improved the trade talks to try get around the us— china trade war lawyers were obviously using that in court and saying, see, this isa that in court and saying, see, this is a political matter, it's not a normaljudicial proceeding. and the canadian government as this court case continues in vancouver, thank you very much. let's take a look at some of the day's other news. president trump has said he would be "very disappointed" if north korea were rebuilding missile test facilities. satellite images taken two days after talks between president trump and kimjong un broke down in vietnam appear to show the rapid rebuilding of structures at the sohae rocket launch pad.

i would be very disappointed if that we re i would be very disappointed if that were happening, we are the ones who put it out, but i would be very, very disappointed in chairman kim andi very disappointed in chairman kim and i don't think i will be, but we'll see what happens, we'll take a look, it will ultimately get solved. also making news today: the brazilian president jair bolsonaro has provoked outrage by using an obscene video to attack the annual carnival celebration. mr bolsonaro tweeted the clip saying such scenes were becoming normal at carnival, and he wanted to reveal the truth. critics have accused the president of retaliation for protests against him during this year's carnival. the venezuelan goverment is expelling the german ambassador for what it says is interference in venezuela's internal affairs. martin kriener has been given 48 hours to leave the country. he was one of the foreign diplomats who went to the airport in caracas to greet the opposition leader juan guaido as he returned to the country. a former close aide of the canadian

r&b singer r kelly's been arrested for the second time in recent weeks, this time for failure to pay child support hours after lashing out in a television interview against charges that he had sexually assaulted teenage girls. he denies the charges. kelly was taken into custody after a court hearing in chicago for owing more than a $160,000 in child support to his ex—wife for their three children. 0ur correspondent peter bowes is in los angeles for us. it's great to have you with us, peter. let's start with the latest development of the non—payment of child port. -- support. this is quite different from the sexual abuse charges he is facing and has walked out of controversial interviews about. this is a hearing about deciding whether he should go

to jail because he hasn't paid child—support payments to his former wife, they have three children together. thejudge in that wife, they have three children together. the judge in that case warned him a month ago that he would go to prison if he didn't come up with more than $160,000 in payments, this was a hearing that took place behind closed doors and after about one hour we learnt that yes, she had been taken into custody once again, he is right now behind bars because he is right now behind bars because he hasn't paid that money. his publicist was there. he explained quite simply that r kelly is broke and hasn't been able to get any work because of the lawsuit he is fighting and that's why he hasn't made these payments. as you know, he hadn't worked in a long time, he can't book shows, he can't do anything. there have been a lot of things going on in his life, lawsuits, all the things that are happening. let me turn to some of

the things that have been going on in his life this interview that took place for example, when he denied the allegations of sexual abuse against him, tell us more. this was quite a spectacle, quite an extraordinary interview, it was breakfasttime across the united states and this was the first time we heard in his own words those reactions to those charges. he was very angry, very emotional, very animated in his defence of himself denying those charges saying things like all you really wanted to do was spent time with his children —— ought he really wanted to do, he got out of his seat, he talked directly to the camera in a way that we rarely see on american television. people in this kind of situation came to be reasonably coached and composed but he later told out there, very emotional and very clearly angry. let's take a small

section from that interview. how stupid would it be for me to — with my crazy part in what i been through — oh, right now, think i'm a monster and chain up girls in my basement against their will and don't let them eat or let them out... stop it! quit playing. i didn't do this stuff! this is not fair. i'll fight for mice wow writes ex— commissioner -- i'll for mice wow writes ex— commissioner -- ru fight for mice wow writes ex— commissioner —— i'll fight for my rights! for mice wow writes ex— commissioner -- i'll fight for my rights! he's been very angry, quite an interesting reaction from the interview —— on the interview from detractors and supporters, some people are saying we are living in a trial by television scenario, let's see what sort of evidence comes

forward in the actual trial in front ofa forward in the actual trial in front of a judge and jury. before i let you go, the timing, was that purely incidental? we know that the interview with just been talking about was done 2a hours ago at his home in chicago, this court appearance was scheduled sometime ago so i think it is a coincidence that these two things are happening at the same time. thank you very much, joining us from los angeles. the trump administration has been under fire for its treatment of migrant families trying to cross into the us from mexico for months. the separation of parents from children caused uproar. today, the homeland security secretary was before congress, calling for america's borders to be secured in the face of what she called "a humanitarian catastrophe. " we face a crisis, a real, serious and sustained crisis at our borders. we have tens of thousands of illegal

aliens arriving at our doorstep every month. 0ur capacities are already severely restrained, but these increases will overwhelm the system entirely. this is not a manufactured crisis, this is truly an emergency. secretary nielsen was also asked about the investigation into two migrant children who died last year in us custody after crossing the border. she said it's ongoing. one of the children who died was 8—year—old felipe gomez alonzo, who'd been travelling with his father. the bbc‘s patricia sulbaran has been to felipe's village in guatemala, to find out what's driving families to make the journey to the us. a wake for a young boy. 8—year—old felipe gomez alonzo dreamed of life in the us but died after crossing the border.

although he died in december, some of these boys have only just found out. before he left he told his sister catarina that their dad was taking him to the us so he could study. he said once he had enough money he would come back for her. pedro was felipe's teacher. twelve children left the school at the end of last year. their parents thought they could give them a better life in the us.

this secondary school was built by a charity but there's no money to keep it going. children here stop studying when they turn 13. guatemala has some of the worst poverty and malnutrition rates in the region, especially in rural and indigenous areas like this one. felipe's family have gone back to the village and now his body is resting here with those of his relatives. although his death was a tragedy for this community, it has not stopped people from wanting to leave, even if it means risking their lives. felipe's mum says sometimes

they can't afford to buy firewood for cooking so they don't eat. in the future, felipe would have been expected, as the older son, to send money home to pay for electricity and running water. as long as the reward of life in the us outweighs the risk of getting there, guatemalans will keep choosing to leave their homes. patricia sulbaran, bbc news, guatemala. you're watching newsday on the bbc. still to come on the programme: the medicine that claims to cure depression in hours — is this the miracle cure for millions around the world? also on the programme: as australia heads towards becoming the top international study destination, warnings remain that universities should not get too used to overseas funding. first, the plates slid gently off

the restaurant tables. then suddenly, the tables, the chairs and people crashed sideways and downwards, and it was just a matter of seconds as the ferry lurched onto her side. the hydrogen bomb. on a remote pacific atoll, the americans had successfully tested a weapon whose explosive force dwarfed that of the bomb dropped on hiroshima. i had heard the news earlier, and so my heart went bang, bang, bang! the constitutional rights of these marchers are their rights as citizens of the united states, and they should be protected even in the right to test them out, so that they don't get their heads broken and are sent to hospital. this religious controversy — i know you don't want to say too much about it — but does it worry you that it's going to boil up when you get to the states? well, it worries me, yes, but i hope everything will be all right in the end, as they say.

welcome back, everyone. this is newsday on the bbc. i'm rico hizon in singapore. and i'm nuala mcgovern in london. our top stories: huawei is set to formally announce that they are suing the us. it comes after meng wanzhou, the huawei telecoms executive, made her first appearance in a canadian court. the us homeland security secretary has been defiant in the face of criticism of how migrant families were treated. during a congress hearing she said that they face a crisis at the border. let's take a look at some front pages from around the world. the japan times takes a look at the innovative buildings that bring east and west together. they're the creations of arata isozaki, who's just been awarded this year's pritzker prize, widely considered to be the profession‘s highest honour. congratulations.

natural flood defences, rich, muddy feeding stations. and, as plants on coastal marshes suck in carbon as they grow, could these places help in the battle against climate change? you can see plants starting to come back in this restored salt marsh, but, when the plants die, rather than just lying and decomposing, these layers of sediments essentially lock that material away in the mud. so that carbon in that plant material is stored in the layers of mud in this marsh. by drilling into the mud, these scientists in the us are taking part in a global effort to gather evidence of how much carbon—rich plant matter is locked into the layers. by comparing different wetlands around the world, they found that, as sea levels rise and wash in more sediment on the tide, even more carbon is buried. future sea—level rise, they say, could cause marshes on the coast

of australia, china, and south america to lock away an additional five million tons of carbon every year. that's equivalent to taking a million cars off the roads. this research could really start to change the way coastal habitats are managed, and maybe make decision—makers think about, when they are putting in infrastructure or changing the land management, thinking about making space for wetlands, because it will help offset the effects of climate change and prevent worse. it could really have a profound effect. the whole cycle of plant growth and carbon burial depends on the tides. solid sea walls and flood defences cut wetlands off and shut that system down. so conservationists are now calling for the protection and regeneration of wetlands around the world, to help fight climate change by ensuring that more carbon remains stuck in the mud. victoria gill, bbc news. a new drug for depression, that's about to be approved in the us, claims it can relieve

severe depression in hours instead of weeks. johnson and johnson's spravato is a nasal spray containing a chemical called esketamine — and it's been hailed as a major evolution in the treatment of depression. esketamine is a chemical cousin of the anaesthetic and party drug ketamine. it's estimated that some 300 million people around the world sufferfrom depression. and mental health disorders are estimated to cost the global economy some $1 trillion in lost productivity a year. i've been speaking dr steven tucker, an american physician based in singapore, about the safety of this new drug. i asked him if he had any association with johnson and johnson. nine. no relation tojohnson & johnson. i am an oncologist by training which makes me a gp for patients with cancer and their families. the last time we had gp we we re families. the last time we had gp we were talking about the treatment for leukaemia in the thousands of

dollars, now we are talking about depression. why, after 30 years, come up with this antidepressant drug. it has been a long time. studies take time, trials take time. this comes from ketamine which for decades has been an approved anaesthetic and has fallen into the domain of being a party drug. now they have been able to isolate one half of the molecule and deliver it through the nose, intra— nasal. and after the studies that are not only is it effective, it appears to work very fast in a subset of people. you mentioned about the drug ketamine. there are concerns about the risk of abuse. and it has a reputation for recreational misuse. i don't think it will be an issue. the drug is only administered in a doctor's office. it is a nasal spray. so receive your nasal injection, your path. then you stay in the doctor's office for 2— four hours. you will

not take any medication is home. it comes with a black box warning, the highest fta label concern. don't you think this is nasal spray should just be the last resort? when it comes to depression it is about counselling, people to people interaction. if that was the only thing that was needed we would not need the numbers you describe, the global epidemic —— we would not have the numbers you describe. there is a neurochemical change in the brain. we have a new drop working through a new pathway. it is not the first choice. it is that leading indicator for something called treatment resista nt for something called treatment resistant depression. theoretically you should have already failed two different antidepressants. very interesting. dr steven tucker speaking to rico in singapore. new figures show that australian universities have seen a 50% rise in the number of international students over the past five years. and many expect australia to soon overtake the uk as a study destination.

nearly half of those foreign students come from either china or india, but there are warnings that institutions shouldn't become dependent on funding from overseas. more from our sydney correspondent, hywel griffith. study business by the surf, it's a compelling proposition, which helped persuade yan from china that sydney was the right place for her degree. she had been to australia before to visit her cousin, but the country also topped a list for cost and lifestyle. i did some research in the uk and america, they are all fantastic study destinations and they all have fantastic educational systems. but i guess with australia it's more financially friendly. and it's more financially friendly. and it feels young to me. australia, it looks to me like they are making their own history at the moment.

education is a big multinational business. the us is the global leader in attracting international students. the uk is in second position. but numbers that have stagnated, while in australia, the third biggest market, there has been a 50% growth in five years. chinese students, in particular, are grabbing the opportunity to come to australia's universities. sydney's uts is typical. 0ne australia's universities. sydney's uts is typical. one third of the foreign student era from china. international students can pay four times the fees of their australian counterparts, and they have to pass a language test to study here. but some academics have warned that they have seen students with very little english. and assignments clearly written using internet translation. that has prompted a warning that universities shouldn't undermine their own success. this is a thing we need to guard really closely comedy standards and the reputation

and the authority of universities. if that gets watered down so we are passing students simply because they are good revenue source, then that isa are good revenue source, then that is a problem. for some students it's life after uni that really matters. matt sim from moscow hopes to take advantage of a two yet these are to start his career here. by 100% staying start his career here. by 10096 staying in a study. i love it. i am obviously working very hard to get my employment here and stay in the country. as enrolments keep on growing, australian universities are clearly feeling the love, with more stu d e nts clearly feeling the love, with more students thinking this is the right move for them. hywel griffith, students thinking this is the right move forthem. hywel griffith, bbc news, sydney. you have been watching newsday. i'm nuala mcgovern in london. and i'm rico hizon in singapore. stay with us for some food for thought. coming up, we will see how one asian family accidentally carved up a business empire.
