PRAGUE, July 21 (Reuters) - The Czech government will discuss the crown's "abnormal" firming but there is little it can do about it, Prime Minister Mirek Topolanek said on Monday.
The crown's long-term ascent reflects economic growth and will not do any harm, Topolanek told reporters.
The central European leader, who prefers a slow path toward adoption of the euro, said the crown's rise was no reason to rush euro zone entry, a step demanded by exporters who have seen their margins slashed.
Topolanek said the crown's recent sharp rise was an anomaly that the cabinet would discuss to see what could be done.
"It is necessary to analyse the abnormal development in the recent period, and the government will undoubtedly consider it," Topolanek said.
But he added he saw little the government could do to stem speculative capital moves or the long-term trend.
"The question is ... if in the long-term, the change in the exchange rate can harm the Czech economy. I do not believe that," Topolanek told reporters.
"The Czech crown is rising in relation to economic growth ... It is not within the powers of any government to solve this situation," he said.
The crown extended its gains versus the euro earlier on Monday, hitting a new record high of 22.935 <EURCZK=>, according to the Reuters dealing system. It slipped back to 22.98 by 1015 GMT.
The currency has gained 18.6 percent versus the euro from a year ago on the back of strong exports and a small current account gap, which has helped it gain status of a safe haven amid world financial turmoil.
Other currencies in central Europe have also risen, supported by the relative strengths of their economies and in most cases higher interest rates than in the euro zone.
Czech economic growth has slowed from last year's peak to 5.3 percent year-on-year in the first quarter and is expected to slacken further, in part due to the strong currency, but still outpace the ailing western Europe.
In daily Hospodarske Noviny on Monday, Topolanek also spoke against an intervention against the appreciating crown.
"Interventions by the (central bank) are usually expensive and ineffective, therefore I do not recommend them," he was quoted as saying.
He also told the paper the crown strength was no reason to speed up euro membership.
The government has abandoned a 2010 euro adoption target date, and has not set a new date yet, while analysts do not expect the Czechs to switch the crown for euros until after 2012. (Additional reporting by Jana Mlcochova, writing by Jan Lopatka, editing by Mike Peacock)
