Britain started to negotiate to exit EU. In this negotiation, Britain will require two things about the British right and management of the border between Britain and Ireland. It is expected that by securing the right of British who are from EU and are in EU now, Britain want to be supported by a nation. If this negotiation has been concluded well, they may be going to talk about their relationships after exit. Specially, we should think about their trade. That is because many Japanese businesses are in Britain. Whether Britain can promote free trade with EU or not will influence Japanese GDP. I hope Britain makes new order of the world.
