(ANSA) - BELGRADE, MAY 21 - "It is our responsibility today to accelerate concrete progress for candidate countries on their path of integration into the European family; the alternative, of which unfortunately some signs are already visible, is that of a weakening of the pro-European drive in public opinion, and thus in the governments, of those countries whose trust in the Union and in its promises of well-being and security we have not been able to adequately nurture," said the Italian President.
