It has been a constant refrain in recent years that, with globalisation, borders no longer matter. Supply chains are global. Capital is mobile across the world. Cashless payments systems cross borders. Pollution is no respecter of borders. Neither are infectious diseases. Data flows through the world wide web. Professionals connect through international networks.
One corollary is that small nations might as well pack up shop. Only the big brigades count (the US, China. India, Nigeria, Russia, the EU). Non-state actors are the future.
Yet, despite these assertions, borders are making a comeback. .Trite thinking ascribes the comeback to 'economic nationalism'. This blog gives seven reasons why they still matter.
