'And what about non-tariff and behind-the-border protection in the form of regulations, standards and licencing? Impeccable work by Simon Evenett, at St Gallen University in Switzerland, regularly provides updates on protectionist trends in its Global Trade Alert. And guess what? The US is singly the most ferocious user of non-tariff protections among all trading economies. In the 25 years from 1990 to 2015, the US has introduced more than 450 protectionist measures, compared with 350 in India, around 260 in Russia, about 140 in Brazil, and a comparatively puny 130 in China.'
