(Updates with finance minister, central banker, Fitch upgrade)
By Marcin Grajewski
BRUSSELS, July 8 (Reuters) - Slovakia cleared the final hurdle on Tuesday towards joining the euro zone on Jan. 1, 2009, when European Union finance ministers set the rate at which the single currency will replace its crown <EURSKK=>.
The EU's 27 ministers fixed the final rate for the Slovak crown at 30.1260 to the euro, which Slovak officials said would help tame inflation while supporting the country's already impressive growth rates.
"Twenty years after the fall of Berlin Wall, Slovakia is becoming the first country from behind the former Iron Curtain to adopt the euro," said French Economy Minister Christine Lagarde, whose country holds the EU's rotating presidency.
EU Monetary Affairs Commissioner Joaquin Almunia said adopting the euro would bring greater price stablity, more jobs and forein investment as long Bratislava continued to pursue sound fiscal policies.
The exchange rate is the same as the central parity level in the Exchange Rate Mechanism, the currency stability test for joining the euro. In the ERM-2, currencies are allowed to fluctuate within a narrow margin around a parity rate.
"It (the exchange rate) will support low inflation development," Slovak central bank governor Ivan Sramko told a news conference.
Credit rating agency Fitch upgraded its rating for Slovakia after the ministers' decision.
Finance Minister Jan Pociatek said adopting the euro would increase economic growth by one percentage point. Slovakia, a major car producer, saw its economy expand by 10.4 percent in real terms last year, the highest rate in the EU.

"Euro entry will be beneficial for our economy. It will attract foreign direct investment and ... increase gross domestic product growth by one percentage point," Pociatek said.
EU leaders last month approved Slovakia's bid to become the euro zone's 16th member, despite European Central Bank concern over sustainability of its inflation rate.
In late May, Slovakia strengthened the crown's central parity rate in ERM-2 by 15 percent in local terms partly to fight inflation.
Inflation is now 4.0 percent, the same as in the euro zone, but some economists say it may grow as it did in Slovenia after it adopted the euro in 2007.
Slovakia will be the fourth of the bloc's new members that joined the EU in 2004 and 2007 to adopt the euro. Much smaller Slovenia entered the single currency zone in 2007, followed by Cyprus and Malta this year.
Bigger EU newcomers Poland, the Czech Republic and Hungary are expected to adopt the euro well after 2010.
Pociatek said an intensive information campaign about the euro would be his priority as well as measures to prevent retailers rounding up prices when the euro replaces the crown.
Euro adoption is seen as the biggest international achievement of leftist Prime Minister Robert Fico's government, made possible by the liberal economic reforms of his centre-right predecessor, Mikulas Dzurinda.
However, Pociatek has faced opposition allegations that information about the May currency revaluation leaked and that local private equity groups booked profits of tens of billions of dollars in subsequent insider trading.
The government has rejected the allegations as groundless, although the central bank has begun an inquiry into unusually large volumes of trade on the small local currency market shortly before the revaluation. (Additional reporting by Peter Laca in Bratislava; Editing by Gerrard Raven)
