The U.S. Department of State has urged Ukraine to pass a package of laws necessary for the signing of the association agreement with the European Union.

"Ukraine, in particular, has three last steps to take to meet the EU's conditions – the passage of judicial and electoral reform legislation, and the release of former Prime Minister Tymoshenko from prison for medical treatment," U.S. Assistant Secretary of State for Europe Victoria Nuland said at a meeting of the Atlantic Council in Washington on Wednesday.

"We join the EU in urging Ukraine's leaders to make the right historic choice for their 45 million citizens – to choose their children's future over the grievances of the past," Nuland said.

She said that two weeks before the EU's summit in Vilnius, it was a historic moment for Ukraine, Moldova, and Georgia.

"All three countries have made advances in rule of law, democracy and market openness in order to meet the EU’s strict conditions for Association Agreements and the Deep and Comprehensive Free Trade Area," the diplomat said.

"The United States welcomes these nations' European choice and wants to see all three knitted into the European family with the kinds of trade benefits and visa free travel the EU offers," Nuland said.
