The document discusses the Committee of the Regions' (CoR) role in promoting multilevel governance in the European Union on the issue of integrating third-country migrants. The CoR acts as a consultative body and advocate for local and regional authorities. It has committed to a "Strategic Partnership" with the European Commission to establish a network of local and regional authorities on integration. This network would facilitate information sharing of best practices, multilevel policy dialogue, and advocacy to involve local and regional authorities in integration policymaking at the EU level.
