Yet many contentious issues between where the us and china have signed these two countries still remain. Areas including technology and innovation could determine the economic and military power of these two superpowers. That has been left the first phase of a trade agreement, signalling a ceasefire for phase two negotiations and until in the trade war that has rattled the global economy. China has promised to buy an extra then Donald Trumps tarus remain on 200 billion a year worth of us farm produce. Two thirds of all us imports from and an extra 75 billion worth of industrial products. China. Michelle fleury, bbc news in return, the us is halving its tariffs or import taxes on 120 billion worth of chinese goods. Tariffs. But most tariffs lets get some reaction now will remain in place. From our Asia Business correspondent a tax of 25 will still be charged karishma vaswani. On chinese imports worth 250 billion a year. And President Trumps biggest complaint that china unfairly subsidises its industries remains unresolved. 00 01 38,893 2147483051 37 34,161 Michelle Fleury reports 2147483051 37 34,161 4294966103 13 29,430 from washington. Here in asia the reaction to the trade deal has been met with some relief. Many Asian Companies may factor their products in china and they have been hit by these american tariffs, too. So this is a welcome respite from the uncertainty of the last 18 24 months, as wendy cutler, the former acting deputy trade representative told us. More certainty, not 100 certainty, but i think businesses now, at least, can navigate over the coming months and make some difficult choices and, perhaps, start actually putting in place some Investment Decisions that they have put off. But, you know, a phase i deal isnt the end of the trade for by any account. Its simplya trade for by any account. Its simply a pause. And tariffs remain on the vast majority of goods on either side. Just to give you the statistics, sally, on average they are 20 higher than what they were before the trade war began. For ta riffs before the trade war began. For tariffs to come down for good another round of negotiations has to ta ke another round of negotiations has to take place and as stephen lamarr, the president of the American Apparel and Footwear Association says, that wont be so easy. We think phase ii cant come soon enough. We are concerned, however, because all the signals are just that phase ii might not happen until the end of the year, if then. That means we have to experience these tariffs for the next ten, 11, 12 months, which definitely means they will result in price increases. And there are still a number of hurdles to ove rco m e there are still a number of hurdles to overcome before we even get to phase two, in the first phase of the deal that was signed overnight, china didnt have to give up subsidies or its state owned enterprises or accept any changes to its made in china 2025 programme, both key us demands. Then there is the enforcement issue, do the us and china have the same understanding of that . Lots of things that have still yet to be resolved. So something to watch very closely. 0k, thank you very much indeed. Lets talk smartphones now, because the worlds addiction to the devices is growing. And new research gives a sense of just how lucrative they have become. Revenues from smartphone use, including spending via apps as well as advertising, soared by a fifth last year to 310 billion worldwide, according to consultants app annie. Almost three quarters of the money we spent via our phones was on gaming. Other than games, tinder and netflix were the big earners. Apple was a clear winner. Its app store accounted for half the spending as much as google play and other Android Stores put together. More than 200 billion apps were downloaded around the world last year. And on average we spent three hours a0 minutes a day looking at our phones thats up by a third in the past two years. That generates a vast amount of data about our habits, which has become hugely marketable, as a bbc report late last year discovered. If the product is free, where is the cost . I think to most of these companies you, the user, im not the customer, the customer is normally an advertiser that takes your personal information will stop its about you having a say and some control over how that information gets used. Surveillance capitalist ta ke gets used. Surveillance capitalist take your private human experience, they turn it into behavioural data, they turn it into behavioural data, they package it is predictions of what you will do now soon and later, and they sell the two business customers who have a very serious commercial interest in knowing about what you are going to do in the future. So much to discuss. We have mike weston from tech consultancy smtwjoins me now. Good to see you. Smartphones are here to stay. We are loving the apps and we are spending more and more time on them. Totally. And there is a distinction between the immobile natives, if you like, generation z and their usage which is about 30 higher than people of my generation, but even so none of us is really immune from us. The days used to think of 55 plus being laggards on smartphones, that is no longer the case. It is a universal peace of mind and all of us seem to have a smartphone with us all the time im we go, even if it is into the toilet. Whatever we are up to it is with us, whether we are using it or not. The concern highlighted there is that this device is listening. Its gathering information about us co nsta ntly a nd its gathering information about us constantly and that is extremely marketable. Completely, yes. Marketing companies, Marketing Technology companies will talk about the idea of getting the perfect message to the right person at the perfect time in the perfect way and this is the data that fuels the ability for us to do that. And thats driving up the amount of advertising revenue we are expecting to be seen driven actually in mobile channels. But it also affects our brought up marketing preferences as well on all devices. The concern is for young users in that sense. For adults, gas, we are aware, we are perhaps more sadly when it comes to privacy and that kind of thing. Maybe we are not, i dont know. Savvy. The younger users, the teens, it isa savvy. The younger users, the teens, it is a huge social experiment and we dont know where it will end. It is a huge social experiment and we dont know where it will endlj think you are right. The interest is the difference in attitude to privacy for the older generation, a0 plus, this is the people who have grown up plus, this is the people who have grown up with this kind of technology being there, and they live their lives in public and they have done from the moment they were more 01 have done from the moment they were more or less, born, to be honest. And that has created a different approach to how important privacy is for people in the emerging generations. But what this means is that regulators, lawyers, et cetera, they have got to catch up with this. It is clear this trend is not going to backwards. Although we understand that the growth is slowing in more mature markets like the us and the uk, but elsewhere in the world, like indonesia and other places in southeast asia, it is just exploding. Absolutely skyrocketing. The reason growth is slowing is once you reach a saturation point account continue to grow. Whats really interesting is we are still growing at 15 in the uk, 10 in the us, 50 in south korea, so those established markets where you think how much more can it go . Three hours and a0 minutes of usage per day, as you say, that figure, i can only see that going up. That is the average. Eye can only see this going up. What are we not doing as a result . And where is the money . It is in apps. Completely. Thanks for your time. Fascinating. And thank you for your comments as well. We are asking you what apps are you want, what are you up what apps are you want, what are you up to, how much time do you spend on your smart phone, confess. Up to, how much time do you spend on yoursmart phone, confess. Hashtag bbc the briefing.

Kyle mcculloch does one to one youth coaching. He has also coached in the us. But a ban on children heading the ball has been in place since 2015.
