"I keep repeating that being ready to become a member of the eurozone in 2014 remains a strategic goal. Of course, it would be good if the eurozone club were in a better and more attractive shape by that time," he said during the Lithuanian Economy 2012 conference.
President Dalia Grybauskaitė said in an interview published last month that 2014 was an unrealistic target for the country's eurozone entry.
Vitas Vasiliauskas, Lithuania's Central Bank governor, said last week that at the moment, Lithuania was not meeting the Maastricht price stability criterion. Keeping its public sector deficit within 3 percent of GDP presents a considerable challenge for the country as well.
Leaders of some non-euro countries in Eastern and Central Europe, and Poland in particular, say that they do not plan to adopt the single currency until the eurozone crisis is resolved.
Kubilius said on Wednesday that what was important for Lithuania was not so much the eurozone as fiscal stability.
"What is very important for us is not so much (to join) the eurozone as a certain monetary policy club, but to learn the lessons of the crisis and to understand that the fiscal discipline, a deficit below 3 percent, and reined-in state debt are what we must continue to steadily implement," he said during the conference organized the Valstybė magazine.
