BRUSSELS (Reuters) -- Swedes may grow more inclined to adopt the euro when more of their Baltic Sea European Union neighbors join the currency, Swedish Prime Minister Frederik Reinfeldt told Reuters in an interview.

"I think that when the euro becomes more and more a Baltic Sea currency, when the Baltic states come over to the euro, I think it will influence the feeling that it's more ... close to the Swedish citizens," Reinfeldt said.

"Then we might see a shift in opinion and then we might reopen the question again. But for the moment, for this mandate period, it's not at hand," he said ahead of a summit of the bloc's 25 leaders in Brussels.

High inflation made Lithuania and Latvia push back their euro entry target dates to 2010 or later, and Estonia has dropped its entry target date altogether.

Poland has not set a date yet and Denmark may never join because it has negotiated a formal opt-out of the single unit.

"We had a 'no' in our (euro) referendum in September 2003. Leaders of different parties made a commitment that they would stick to it, they actually mentioned up to 10 years," Reinfeldt noted. "I think that given that we have not seen a shift in opinion in Sweden, we have said that for this mandate period that now starts and ends in 2010 the question will not be raised."
