(79)Union CCPs provide services to clearing members and their clients located in third countries and third-country CCPs provide services to clearing members and their clients located in the Union. Effective resolution of internationally active CCPs requires cooperation between Member States and third-country authorities. For that purpose ESMA should provide guidance on the relevant content of cooperation arrangements to be concluded with authorities of third countries. Those cooperation arrangements should ensure effective planning, decision-making and coordination in respect of internationally active CCPs. National resolution authorities should recognise and enforce third-country resolution proceedings in certain circumstances. Cooperation should also take place with regard to subsidiaries of Union or third-country CCPs and their clearing members and their clients.
