... Schwarzenberg said on Tuesday.
German Chancellor Angela Merkel is using the German EU presidency in the first half of the year to try to revive the document agreed by the bloc's governments, though rejected by voters in France and Netherlands in 2005.
A new centre-right government in Prague told Merkel last month that the treaty was too complex and bureaucratic but stopped short of saying whether they would reject it outright.
"It would be better to start from scratch," Schwarzenberg told Reuters on the sidelines of a business conference in Warsaw. "Evidently that won't be possible. So we'll work with the old draft."
Schwarzenberg said he hoped the treaty would reduce bureaucracy in Brussels.
"We need a great European deregulation, similar to what (former U.S. president Ronald) Reagan did in the U.S.," he said.
Czech Prime Minister Mirek Topolanek told the conference the constitution must be simplified so that it is intelligible to the general public and that the European Union must reform its public finance system and liberalise its markets.
