The Czech government said Wednesday it would not set a date for adopting the euro, citing a lack of support from the majority of the population.
The central European country of 10.9 million pledged to adopt the euro when it joined the European Union in 2004.
But its Finance Minister Zbynek Stanjura said national backing for the move was not strong enough.
A poll by the STEM agency last year showed that only one in four Czechs wanted the country to join the eurozone.
"Unless the backing grows to at least 50 percent, it does not make sense to give up on our national currency with its long tradition," Stanjura said in a statement.
"The experience of other countries that have joined the euro in the past shows support from inhabitants is the key factor," he said, adding there were no "clear economic reasons for or against euro adoption".
To enter the EU's two-year pre-accession Exchange Rate Mechanism -- a sort of waiting room for countries before they join the eurozone -- each country must comply with limits for inflation, government finances, the exchange rate and interest rates set out in the so-called Maastricht criteria.
The finance ministry said the EU member of 10.9 million people had not met all criteria in 2024.
The centre-right four-party coalition government of right-wing Prime Minister Petr Fiala said it would seek to comply with the Maastricht criteria when it took office in 2021.
But Fiala's Civic Democrats -- the strongest party in the ruling coalition -- are torn on the issue as conservative members are against joining the euro.
The other three coalition party leaders and President Petr Pavel have spoken in favour of euro adoption.
The move would also be welcomed by local businesses including three large car plants, whose exports target largely the eurozone.
But all proposals to discuss an adoption date have been doused by the conservative powerhouse.
Billionaire Czech ex-premier Andrej Babis, who is widely tipped to win a general election later this year, also opposes joining the euro.
The eurozone currently comprises 20 nations.
