She made the statement today at a news conference in Berlin following talks with Ukrainian Prime Minister Viktor Yanukovych.
Talks between Merkel and Yanukovych focused on drafting a new Ukraine-EU cooperation agreement, whose current version expires in 2008.
Yanukovych acknowledged Ukraine has "much to do" to meet EU standards. He said the EU has signaled it is not shutting out Ukraine.
"Most importantly, we have received a signal that the doors of the European Union are open for Ukraine," Yanukovych said. "And this will be stated in the new agreement [on relations between Ukraine and the EU] for the next 10 years."
Merkel, whose country holds the rotating EU Presidency, did say, however, that she supports plans for a free-trade zone between the EU and Ukraine.
