* Czech, Romanian output strong, points to recovery
* Czech retail sales recover after 17 months of falling

PRAGUE, May 7 (Reuters) - Czech and Romanian output data showed a strengthening recovery in eastern Europe, driven by exports as well as signs of revival in domestic demand, that cast doubt over the need for the monetary stimulus provided by Czech policymakers this week.
Czech industrial output rose 10.2 percent, above a forecast 8.5 percent rise, as orders picked up on rising demand in the Czech Republic's biggest trading partner, Germany.
Retail sales rose 3.9 percent year-on-year in March, the first rise after 17 months of contraction and significantly above forecasts for a 0.1 percent expansion.
Romanian adjusted industrial output rose 5.2 percent year-on-year in March, and reversed a 2.5 percent monthly contraction in February to a 3.6 percent growth, a good signal in a country tapping an IMF aid.
The data bodes well for the region, showing the Greek turmoil has not affected its economies. But the figures did not reverse investor flight from risk, including eastern European assets, spurred by concerns over Greece.
Central European economies such as the Czech Republic and Hungary have been recovering on the back of a pick up in foreign demand for their industrial goods.
Romania's growth, on the other hand relies on domestic consumption - voracious before the crisis. But high unemployment and a lending freeze have kept domestic demand weak, which is one of the reasons Romania lags peers in returning to growth.
The Czech economy should reverse a 4.1 percent contraction in 2009 and grow slightly this year, driven by foreign trade.
But the central bank said on Thursday the outlook for external recovery and Czech exports was a downside risk, a statement that many on the market said was puzzling.
Rate-setters surprisingly cut interest rates to a record low 0.75 percent.
"The new numbers are showing that the central bank's pessimism is probably exaggerated and economic growth in the Czech Republic this year could exceed its expectations. The decision to cut rates was probably premature," said Vojtech Benda, senior economist at ING Commercial Banking.
Most analysts said the bank would hold its fire after the Greek debt crisis spurred investor' flight from risk, including central European assets, knocking down the crown by 2 percent over the past week.
The central bank reiterated its outlook for 1.4 percent growth this year and cut its 2011 forecast to 1.8 percent from 2.0 percent, which some analysts said could be due to developments in Greece which may lead to fierce fiscal tightening across Europe.
The statistics office also said foreign trade surplus rose to 18.3 billion crowns from 14.6 in February, with both imports and exports rising at double digit pace and above forecast.
