Tariffs have historically been an important tool of industrial policy. They were used in the last century by east Asian nations to promote infant industries, and are being used today by the EU to help spur the energy transition. But do Donald Trump’s threats to impose a 25% across-the-board tariff on imports from Canada and Mexico, or his actual 10% tax rise on all imports from China, have any kind of thought-out policy rationale behind them? And should other countries respond in kind? 

To find out, the FT’s European economics commentator Martin Sandbu speaks to Dani Rodrik, professor of international political economy at Harvard. Rodrik is one of the world’s most acclaimed experts on industrial policy, and someone Martin first got to know as a PhD student in the 1990s.
