PRAGUE, May 5 (Reuters) - A stronger than expected global recovery will help lift most of the European Union's newer eastern members out of recession in 2010, although they will struggle to meet budget deficit targets, the European Commission said.
A report released by the EU's executive on Wednesday showed Poland, the bloc's only member to avoid economic contraction last year, would lead the non-euro zone states, with 2.7 percent growth this year, accelerating to 3.3 percent in 2011.
"The recovery is expected to gain momentum in 2011," the Commission said.
Slovakia, which adopted the euro in 2009, was seen growing by 2.7 percent in 2010. The Czech Republic, Estonia and Romania, would show growth of up to 1.6 percent, while Hungary and Bulgaria were expected to stagnate.
Forced to tap an EU-led bailout in 2008, Hungary is still trying to trim its bloated public sector and reduce its budget deficit, a factor the Commission said would weigh on recovery.
"The output of export-driven industries is expected to accelerate faster than that of domestic-driven sectors especially as the latter are heavily affected by the ongoing fiscal adjustment," the Commission said.
As in the other countries, rising demand for manufactured products would drive Hungarian growth, but there would be a drag from the effort to trim the public sector and raise tax revenues.
The only economies from the former Communist bloc expected to shrink this year were Lithuania and Latvia, with the former down 0.6 percent and Latvia, which suffered an 18 percent contraction in 2009, expected to decline 3.5 percent.
Inflation was seen subdued except in Hungary and Romania, where it was seen hitting 4.6 percent and 4.3 percent respectively in 2010.
Central banks in those two countries have been the only two to continue lowering interest rates to try to counter steep economic contractions since the rest of the region concluded their easing cycles last year.
In contrast, Latvia was expected to register deflation of 3.2 percent this year.
FISCAL ADJUSTMENTS
Budget deficits remained a key concern. The Commission saw Poland's public deficit stabilising at around 7 percent of gross domestic product through next year ahead of 2011 parliamentary elections.
But it forecast public debt rising almost three percentage points to 53.9 percent of GDP this year according to EU accounting standards, and to 59.3 percent in 2011 if policies remain unchanged.
That level could potentially trigger steep public spending cuts due to a Polish constitutional requirement to keep debt below 55 percent of GDP using local accounting.
The three non-euro members that took EU, World Bank and International Monetary Fund bailouts at the start of the crisis -- Hungary, Romania and Latvia -- would also have trouble meeting their fiscal targets.
In Romania, lower than expected growth, a higher than forecast deficit in 2009 and a big revenue shortfall in the first quarter would probably push the fiscal shortfall beyond the 5.9 percent of GDP agreed under its aid programme.
"Without further measures, the 2010 general government deficit could reach 8 percent of GDP," the report said.
That meshed a comment from a source with knowledge of talks between Romanian and IMF officials, who said the IMF would accept a petition from Bucharest for a higher deficit target.
"For sure we are going to see a revision of the budget deficit target," the source said.
In Latvia, big cost cuts and tax hikes have still fallen short of plan and the government deficit will be above the government's 8.5 percent of GDP deficit target, the report said.
For Hungary, the Commission forecast a 2010 general budget deficit of 4.1 percent of GDP, higher than the 3.8 percent goal.
It added that further reduction would be needed, which conflicts with a plan by Hungary's new right-of-centre government to negotiate a higher ceiling.
"Hungary has to put an end to its excessive deficit by 2011 at the latest, which implies a need for further deficit-reducing measures at the latest next year of more than 1 percent of GDP," the report said.
