hizon. we start off with huawei, and the chinese telecommunications giant says it will challenge us efforts to severely restrict how it does business. well, on thursday, the trump administration moved to stop huawei buying components from the us and selling its own equipment there. it is all because the us is concerned that huawei helped the chinese government to spy, something the firm has repeatedly denied. our reporter is investigating with more details from new york. well, the sta kes details from new york. well, the stakes could not be higherfor huawei, but they have really tried to turn the conversation on the americans. in their statement they pointed out that this doesn't just hurt huawei. it hurts american businesses that sell to huawei, and they have talked about the thousands ofjobs they have talked about the thousands of jobs that could they have talked about the thousands ofjobs that could be lost if this ban ofjobs that could be lost if this ba n stays ofjobs that could be lost if this ban stays in place. they have talked about how share prices in these companies and the economic damage that could be done. so they are trying to focus on this being a larger economic impact than just on

huawei and today we saw shares in companies like micron technologies, that sell semiconductors, they went down today. so there is more at sta ke, down today. so there is more at stake, and huawei is trying to focus the us on those concerns while saying it is open to a conversation with them about how they can fix this. indeed, the repercussions are big. and the us, zoe, has already given more details about this band. what have they said? -- ban. so the big news today is this ban goes into effect immediately. yesterday when we got some details about it that was unclear, but the commerce department today said that huawei will be banned from buying from american suppliers immediately. they have also said that anybody who wa nts to have also said that anybody who wants to supply huawei will be dealing with something of a presumption of denial. that is important because it means that even if you want to get approval from the us commerce department to sell to huawei, the commerce department is going to ask those companies to explain why it is not against

national interests and national security interests to sell to huawei, and that's a very difficult argument for them to make. zoe thomas in new york. in other business news making headlines, boeing says it has completed a development of a software update for its 737 max aircraft, which were grounded following two fatal crashes. more than 200 test flights we re crashes. more than 200 test flights were done and the federal aviation administration expects boeing met the upgrade for certification next week. microsoft and sony have announced a partnership on videogame streaming. this comes despite their fierce rivalry in the sector through their xbox and playstation consoles. sony is expected to use microsoft's cloud computing service to hosted streaming service. sony might have struggled to compete in online gaming without the deal. the company said that they would also work together on semiconductors and artificial intelligence applications. indians make up the

largest day as per in the world, —— diaspora in the world and many send money back home. they add almost $80 billion into its economy, yet for indians living abroad, taking part in the country's ongoing general election requires them to actually go back to india. monica miller has the details from delhi. volunteers in india's marathon election haven't lost the enthusiasm to spread their message. this group includes indians who have travelled from abroad to campaign and cast their vote. but this man has joined campaign and cast their vote. but this man hasjoined this event in the labyrinth of old delhi for the b] p the labyrinth of old delhi for the bjp party. the chemical engineer lives in the united arab emirates. he wants it to be easier for non—resident indians, known as nris, to cast their votes from abroad. we

have sent numerous letters to election commissions to request that they should consider allowing voting. this man flew in from london. he was born in india but has called the uk home for most of his life. this is the first time he has voted in an indian election. you experienced brexit in the uk, and what happens when people are apathetic to voting. every vote counts, and given that there is no opportunity for postal votes, i thought, why not? indian residents who live in places like dubai, russia, china and the uk flew all the way home to cast their vote in this historic election. there is one thing that these two major parties agree on, and that is to make this process easier. this man is a banker who now lives in london. he says that the current system doesn't work for him. it's too expensive to go back to india just to vote, and i

also have to take a separate holiday, plan an entire thing, which is very difficult given the job that i do. it is hard to say how many nris have travelled back to india for this election. but one member from the national congress says the diaspora can still be influential. these people who are living abroad, they have family living in india, they have family living in india, they have family living in india, they have friends, and they listen to them, and that impact is huge. they have friends, and they listen to them, and that impact is hugem the meantime, they will have to log more travel time to fulfil their civic duties in person. from india to australia, and saturday is election day there, where conservative prime minister scott morrison is in a tight race with labour's bill shorten. whoever wins, they will be pressure to do more to tackle climate change. 0ne they will be pressure to do more to tackle climate change. one recent poll showed more than 60% of voters thought it was the country's leading critical threat. but that is at odds

with australia's economic reliance on mining exports such as coal. 0ur correspondent is an analyst with capital economics. i think there is also an economic case to shift to renewable energy. according to the australian government, renewable electricity generation is now cheaper than coal so if the australian government decides rationally, they will have to increase the share of renewables, and that is what labour wants to do, i think that is going to happen. and of course, the government wants to push forward, and one of the main platforms is a budget surplus continuing for the australian economy. if the industry is hit, how could this impact the budget? well, obviously it depends more on the development of global commodity prices. as long as global commodity prices. as long as global commodity prices hold up, the profits will be big and they will contribute, and the cash flows will remain high. i don't think any decision australia

will have on what kind of electricity, how it will be generated, will have a big impact on the commodity prices, so the impact is going to be quite small. he is a billionaire fashion tycoon who made news headlines when he announced that he would be spacex's first private customer to fly to the moon, but is he now struggling for money? he is selling artworks worth millions of dollars at a sotheby‘s option in new york. what is going on with him? well, he is very well known in japan. made with him? well, he is very well known injapan. made his money from japan's biggest online clothing retailer. but i think the first time he made headlines internationally was when he bought this painting for $110 million. and he is a known art collector, but he tweeted a few weeks ago saying that he would sell two of the artworks that he owns,
