 abstract={The coronavirus pandemic has prompted the Member States to reintroduce controls at internal Schengen borders. In response to their unilateral actions, the European Commission (EC) presented control guidelines aimed at protecting the flow of goods and returning citizens to their countries. At the EC's request, country leaders also agreed to temporarily close the external borders of the EU and the Schengen area. These measures will ease tensions between countries and reduce the risk of paralysis of the single market. They may not, however, prevent further loosening of the Schengen agreement.},
