The UEFA delegation, led by UEFA secretary general David Taylor, started its four-day, six-city visit to Ukraine on Monday.
"The delegation ... was satisfied with what it saw in Ukraine," the press service of Deputy Prime Minister Ivan Vasyunik announced.
Taylor noted that preparations by the Ukrainian cities due to host games - Kiev, Kharkov, Dnepropetrovsk, Odessa and Lvov - did not seem to have been affected by the global financial crisis.
"I and the delegates have been amazed, both by the city itself and the preparation being currently done by the local and regional authorities as a united team," local media reported Taylor as saying in Kharkov.
The delegation was accompanied on its visit by Vasyunik and the president of the Ukrainian Football Federation, Hryhory Surkis. It will now travel on to co-hosts Poland.
The visit came after concerns over Ukraine's readiness to host the tournament. UEFA President Michel Platini warned in December that all the games could be switched to Poland if Kiev did not complete construction work on the capital's Olympic Stadium.
