(ANSA) - BELGRADE, OCT 9 - "How can the Hungarian government invite Russians into the EU without additional controls? This poses a security risk not only for Hungary, but for all 27. How can Hungary allow Chinese police forces to operate? This does not strengthen European sovereignty, but rather opens the door for foreign interference." Ursula von der Leyen, President of the EU Commission, made this statement in an address to Viktor Orban in the European Parliament. (ANSA).
