First changing borders encouraging development relies on the assumption that there won’t be conflict. Second if independence movements gain independence then there will be a lot more international borders and the barriers to trade these impose. Finally we need to think about this the other way around; when there are ethnic groups on both sides of the trade they are encouraging and facilitating trade between the two states – this is something to be encouraged not changed. Having the same ethnicity on both sides of the border works in the same way as having emigration in encouraging trade. Because of networks overlapping between the two countries trade will increase. In Spain for example doubling the number of immigrants leads to an increase in exports to the immigrant’s country of origin by 10%.
