The impact of US tariffs against China on US imports: evidence for trade diversion?

In this paper we provide evidence on the existence of short-run trade diversion effects as a consequence of tariff shocks. We exploit sudden policy changes in the context of the trade dispute between the US and China. Based on a data set covering monthly product-level information on US imports from 30 countries for the period January 2016 until May 2019, we employ a difference-in-differences estimation framework. Doing so, we (1) can confirm previous findings showing a strong negative direct effect of US tariffs on US imports from China, but (2) do not find evidence for significant short-run trade diversion effects towards third countries. This latter finding holds for product and country subgroups as well as for a variety of robustness checks.
