china are the threat for the world economy markets remain shaken after washington announced plans to more than double tariffs already imposed on two hundred billion dollars in chinese exports the dow dropped more than five hundred points in tuesday trading. and our financial correspondent yes court is on wall street for us a difficult day on the markets but who's been hardest hit. well pretty much all across the board at some point blue chips were down by as much as six hundred fifty points and for certain you have on one side all the big multinational companies who do quite some business was china among the biggest loser kater pillar or boeing just to name a few will but overall there is the sense and fear that if the trade mission good negotiations should fall apart that the global economy actually will be heard so

also companies that do not do a direct business with china but was other overseas markets are also seeing some pressure as far as we know now on wednesday trade negotiations will continue in washington but what really caused the markets to get so nervous are comments by. who actually announced that terrorists will be increased in on friday this is not set in stone but this is what the speculation is that this moment and that actually put quite some pressure on stocks all over the place market moving news there but not the only bit because the first tech unicorn to go public this year has also posted its earnings report and we're talking about left of course how did it to. the well and those numbers were crucial because we are waiting for the big i.p.o. off on friday and the numbers cell phone lift were mixed on one side could

which he said would give people more control over how google tracks them. our mission now is washington bureau chief alexander phenomena joins us now from the iowa developer conference good to see you alexandra now you've been listening to the presentation there seem to be a thousand product updates what stood out for you. actually two things i would say first of all the advanced google lands in google's search the tool is not only helping you know to search for thing you need but it also helping you place them in your place like for example when you're looking for shoes you can not only have a look at them but you can also place them in the your room to see if they match with the rest of your clothes and of a tool with google lens is that when you put the camera on the sign a text or a document google ends can translate the text into a language and it can also read it out loud and that's of course very help for

people who cannot read or have problems with reading another thing that i found quite amazing what the next generation of the google assistants that is according to google ten times faster and now better and it helps you navigate through different apps and you don't even have to say hey google anymore. fascinating developments there but this isn't just a chance for google to present hardware and products but it's also an opportunity for google to tell the world where it's going so what do you think of the message that they've sent so far you know as you can imagine the message chia was very opposed to tive speech i told the crowd that there are moving from a company that helps you find answers to a company that helps you to get things done and that is describing very well what

a number of years this new model gets its power from overhead contact lines using a pantograph. the silence this is the friends. when you turn off the internal combustion engine and go electric. you still have a little noise from the tires of course but you have no white brazen and no sign sound from the days of that. there are five kilometers of overhead contact lines in each direction on this stretch of the out obama with tests on the way in northern and southern germany. this is standardized the highway they bought it has the same all over the height is the same so this truck can also go in the swedish road and they can also go on the road saying. about a bit of oh well connected to the overhead lines of trucks battery charges so it needs much less battery volume than a purely battery trip in each truck. the battery is physical

sizes from here to here and about sixty centimeters deep the rest of the box is cooling and power electronics to keep the battery cool or warm depending on the weather outside in a few weeks five logistics companies will start delivering goods via the highway the overhead line will save companies time you have to move to the end but here i have the possibility to load the view and during operation i can make my delivery my pickup truck back to the loading location and can load again at the same time basically if you do it right the battery is never empty and you never need to plug in the vehicles battery or refuel diesel between trips like i need to show that's a huge advantage that michelin is just full until today. electro trucks running off the overhead contract lines are quiet and environmentally friendly but they're only

by allowing workers to dress more casually and turn the office air conditioners down. it's a significant day in japan as it's the first official working day of the reign of japanese emperor naruhito inaugurating the railway era the new emperor also went into the office for his official duties. the king wished it was hot during the holidays so i dressed lightly today my sight is the only iraq i know so i'm looking forward to the new period. normally the japanese office environment is a formal stuffy one but in two thousand and five in an effort to combat global warming japan introduced an initiative to cut household greenhouse gases by forty percent. at the environment ministry windows were open and workers were dressing down. and that's it for me and the business team and berlin for more business news and features you can always go to d.w.
