From the Document: "In response to the COVID-19 [coronavirus disease 2019] pandemic, countries all over the world, including the United States, have imposed temporary restrictions on exports of certain medical goods and some foodstuffs in order to mitigate potential shortages of key supplies. Many measures are not explicit bans, but vary from licensing requirements to mandates for sales to the state. These restrictions have raised debate about the consistency of such actions with World Trade Organization (WTO) rules and the potential impact on the global trading system. Some markets depend heavily on countries that have implemented restrictions. Most leading exporters are also major importers of critical supplies, with integrated supply chains at risk. The proliferation of such measures has prompted some countries to commit to limit restrictions or to abide by certain principles in their temporary application. Members of Congress have weighed in on both sides of the issue, both in terms of the immediate disruption from COVID-19, but also on the future of supply chains."
