BRUSSELS, Jan 19 (Reuters) - The global economic downturn is set to complicate but not derail efforts of the European Union's new member states from central and eastern Europe to join the euro zone, EU forecasts showed on Monday.
The European Commission revised down sharply growth outlook for the countries and raised forecasts of their budget deficits, suggesting more difficulty then previously thought in meeting criteria for adopting the currency now shared by 16 nations.
But in a special forecast, the European Union's executive arm said Poland, the Czech Republic, Bulgaria and Romania will escape recession that has hit the euro zone, while some countries will keep their fiscal shortfalls below the 3 percent of gross domestic product required to join the euro area.
"The outlook for euro zone enlargement is generally bad," said Lars Christensen, chief analyst at Danskebank.
The Commission revised down its growth forecast for Poland, the biggest country in the region, to 2.0 percent in 2009 and 2.4 percent in 2010, from 3.8 percent and 4.2 percent anticipated respectively in a previous forecast in November.
"Private consumption is set to slow down in 2009, and again in 2010, on the back of a worsening situation in the labour market," the Commission's report said on Poland.
Poland's budget deficit is forecast to grow from 2.5 percent of gross domestic product in 2008 to 3.6 percent in 2009 and 3.5 percent in 2010, more than its government expects and above the 3.0 percent limit.
Poland hopes to join the euro zone in 2012, meaning its deficit should be below that level in the preceding year and forecast to stay that way.
"In theory, the Polish government can still push for the euro ... but it will be difficult," said Christensen, adding he believed the Commission's forecasts were too optimistic.
Out of the 12, mostly ex-communist countries that joined the EU in 2004 and 2007, Cyprus, Malta, Slovenia and Slovakia have already adopted the euro.
EURO/GROWTH DILEMMA
Poland and other countries will face a dilemma on whether to try to boost economic growth with fiscal measures or try to trim the deficit to qualify to join the euro, analysts say.
The EU forecasts showed the Czech Republic might have the best chance tor meet soon euro entry criteria faster than others, which also include sufficiently low inflation, long-term interest rates and currency stability.
Inflation is expected to remain relatively benign in the region, although it is likely to be markedly higher the Baltic republics, Bulgaria and Romania than in other countries.
The Czech Republic, which has said it could join the euro zone in 2013, is expected to keep its deficit below 3 percent in 2009 and 2010 -- at 2.5 percent and 2.3 percent.
The Commission scaled down its growth forecast for the Czech Republic to 1.7 percent in 2009 and 2.3 percent in 2010 from previous 3.6 and 3.9 percent.
The euro zone's economy is expected to shrink by 1.9 percent in 2009 and grow by 0.4 percent in 2010.
Hungary, which only in 2006 had a staggering deficit of 9.3 percent, is forecast to trim its shortfall to 2.8 percent in 2009 and 3.0 percent in 2010.
The Hungarian economy, which has had to seek International Monetary Fund help to support its markets, is expected to contract by 1.6 percent this year before returning to 1.0 percent growth in 2010.
The forecast confirmed the financial crisis has hit the Baltic republics especially hard in central and eastern Europe.
Latvia, which has also sought IMF help, is forecast to see its economy shrink by 6.9 percent in 2009, the biggest contraction in the 27-nation EU, and by 2.4 percent in 2010.
Lithuania's GDP is to fall by 4.0 and 2.6 percent in 2009 and 2010 respectively, while Estonia will return to growth of 1.2 percent in 2010 after contracting by 4.7 percent in 2009. Bulgaria and Romania are both expected to see growth rates at 1.8 percent and 2.5 percent in 2009 and 2010, but the previous will have a budget surplus while the latter's shortfall will shoot to 7.5 and 7.9 percent.
