(ANSA) - BELGRADE, 23 SET - "Today, supporting Ukraine means defending not only a single country's sovereignty and territorial integrity, but also the principles that underpin Europe's security and stability. It is critical that the international community's commitment remains united and tangible," said Franco Dal Mas, Secretary General of the Central European Initiative (CEI), on the sidelines of the sixth International Crimea Platform Summit, which he attended. The summit was held in New York during the 81st session of the United Nations General Assembly. (ANSA).
