"Today’s South-East European Cooperation Process (SEECP) Summit in the ancient port city of Thessaloniki, a great center of trade and ideas over many centuries, comes at a critical moment. It presents an opportunity to meet and exchange in-depth ideas with my fellow leaders, and take stock of where we are and what urgently needs to be done," Prime Minister Kyriakos Mitsotakis said on Friday in an interview with Politico.
