The COVID-19 pandemic brought many changes to social behaviours in Europe. One of its major consequences was the temporary closure of borders, which was introduced as a measure to prevent the uncontrolled pandemic spreading and involved internal Schengen borders. This has had a major impact in the way in which cross-border cooperation has been conducted in Europe, including the Czech-Polish borderland, as it dramatically restrained all flows across borders. In this paper, we evaluate the impact of the pandemic on five roles of cross-border cooperation: 1) as a multi-level governance form; 2) as a regional development tool; 3) as a para-diplomacy form; 4) as a post-conflict reconciliation tool; and 5) as Europe-building. We argue that the impacts of the pandemic complicated regional development and the Europe-building role of cross-border cooperation in the Czech-Polish borderland. The article envisages re-bordering processes also in the Czech-Polish borderland, but with important exceptions in the regions with a high level of cross-border integration, mainly in the Euroregion Těšínské Slezsko/Śląsk Cieszyński. The paper also calls for the elaboration of the guidelines for possible repeated (Schengen) border closures and proposes modifications of the INTERREG microprojects schemes, to keep them attractive also in times of expected cuts in public finances.

The Czech–Polish border is almost 800 kilometres long. Since 1991, 6 Euroregions and two European Groupings of Territorial Co-operation (EGTC) were created and have been conducting cross-border cooperation (CBC) along the entire length of the border. This was probably also the institutionalisation of cross-border co-operation, what has helped to reach and maintain a high level of mutual Czech–Polish relations. What can therefore be considered striking or surprising is a rather low level of cross-border labor mobility between the labor forces of both countries. Authors therefore attempted to identify projects and initiatives in the field of the cross-border labor market along the entire border. Research showed that the CBC stakeholders don’t prioritise co-operation in the field of the labor market, as they don’t see any real cross-border demand. There are some exceptions, driven mainly by the automotive and mining industries in Czechia attracting a Polish workforce. The main reason for the relatively low level of Czech–Polish cross-border co-operation in the field of the labor market is an absence of a major economic engine on either side of the border, rather than any kind of hostile or re-bordering sentiments in mutual relations between subjects from both countries.
