(ANSA) - BELGRADE, MAR 16 - "I have not followed these discussions in detail, but it is clear that Poland is a very strong European member state, and, particularly on the eastern flank, its support for Ukraine, as well as its role as a logistical hub for Ukraine, has been critical," EU High Representative Kaja Kallas stated upon her arrival at the Foreign Affairs Council, regarding Polish President Karol Nawrocki's veto of the EU defense investment program. "I hope it remains so," she added. (ANSA).
