Has been reshaping its trading relationship with the rest of the world. Over the weekend china threatened to retaliate if the us went ahead with proposed tariffs on steel and aluminium imports. So a high level un led meeting in geneva is looking at the way ahead. In many parts of the world the importance of multilateral trade deals can be seen in the number of people theyve lifted out of poverty. The World Bank Says the number of People Living in extreme poverty has halved since 1990 because of free trade. But President Trump has been wringing the changes. He pulled out of the Trans Pacific partnership which would have covered about 40 of the World Economy and is seeking major changes to the nafta free deal between mexico, the us and canada which is worth more than 1 trillion a year. Whilst President Trump says hes trying to secure american jobs the us chamber of commerce says 41 million of them depend on international trade. But the relationships behind it are showing signs of strain. As i said china is warning it wont take us tariffs lying down. Our correspondent robin brant is in shanghai. Just tell us about some of the conversations going on over the weekend . This is the latest chapter in what increasingly looks like a potential trade war between Donald TrumpsUnited States and china. We had that decision from the Commerce Department s in the states on friday, giving the green light to the president to decide if he wants to impose new tariffs on steel and aluminium imports into the states from china and at this catchall and roller umbrella, that they believe the way it china subsidises its Steel Industry is a threat to National Security in the United States. China has said that it is groundless, unrealistic and has said if there are new tariffs to come from the president it will take the necessary measures to protect what it says are its right. Writes. Donald trump is proudly a protectionist as the president of the United States, we have action against solar components from china, washing machines from south korea last month and the decision will come from the president as to whether he will impose these tariffs perhaps later this month. The big thing for him is the trade deficit between the two countries, china sends a lot more to the states then the states sends to china but interestingly, the export it sends are worth a lot more to the chinese economy then slice that the us sends the other way to china. The big issue for American Business is the issue for American Business is the issue of reciprocity, access to the markets here, that is what their ongoing big concern is here. With me is the economist and trade expert Cornelia Meyer who runs the cosultancy mrl corporation. You were listening to rob and there, you were also in davos at the World Economic forum where this was explained at length because the official announcement was given about the tariffs. Over the weekend things have got even more feisty, havent they . Yes, it is disconcerting because really, if you look at it, on the face of it, the biggest importer of steel and aluminium into the us is canada. The reason the us gets hot under the collar that china is producing more than 50 of all steel and aluminium at relatively low cost. But this shouldnt he carried out in an ideal world, ina shouldnt he carried out in an ideal world, in a bilateral thing is that we have a World Trade Organization which has dispute resolution mechanisms and global trade only work when it is really multilateral when the biggest players are getting out of it into bilateral spat is, thatis out of it into bilateral spat is, that is when you undermine the global system. At the same time this is going on, there is a spat getting more acute, we saw footage of President Trumps trip in november where he was, i remember, we will live with his speech, he was gushing in beijing about the special relationship between them. It seems they dont go together. I wanted to ask you about this un meeting in geneva taking place, tell us about special Group Meeting and what difference they can make. It is good to talk. What they are trying to do, it is the Un Organisation for trade and development, they are trying to ta ke and development, they are trying to take the whole multilateral trade issue in context with the Sustainable Development goals, which we should achieve i 2030. By. This is putting that into context but when it comes to the dispute and dispute resolution, the wto is the first port of call. If the barriers are not going up and there are blockages to trade, quite often the losers can be those in poorer developing nations. Absolutely. The losers are, china is a big way, the us isa losers are, china is a big way, the us is a big boy, the losers will be vietnams and the smaller countries who depend on trade to lift their country out of poverty. A multilateral system really only works when you have global rules and people adhere to the global rules, cowboy actions are not helpful. They differ coming in, always good to see you.

Much in line with the rate in asiapacific.

Last september, the family moved to the netherlands so alfie could be prescribed medical cannabis oil. His parents say he went 2a days without having a seizure. Theyve now moved back to the uk, but cannabis oil is illegal in britain, so they want the home secretary amber rudd to give alfie a license to use it.
