Jens Herpolsheimer Inspired by recent blog posts on the regional dimension of responses to the current pandemic of the Coronavirus disease (Covid-19), this paper by Jens Herpolsheimer echoes the warning against methodological nationalism and the neglecting of regional and interregional dimensions in the responses to the crisis. It focuses on Economic Community of West African States (ECOWAS) as an example of one of the Regional Economic Communities (RECs) that have remained rather ignored by scholars compared to the attention paid to the African Union, especially with regard to the African Peace and Security Architecture (APSA) but also to other fields of cooperation, such as health.
