Abstract Despite pleas from international organizations, governments and trade economists to refrain from imposing trade-distorting measures, over 20 countries have implemented bans on the export of agri-food products since the onset of the COVID-19 crisis These export prohibitions might adversely impact food security and disrupt well-established global supply chains We identify importing countries that could potentially be affected by the imposed export bans using a measure of their import dependency during the pre-pandemic period to illustrate our results on global trade maps We find that many importers rely on just one country for a significant share of the overall domestic supply of a particular commodity [EconLit Citations: F10, F13, Q17, Q18]
