Jacques Chirac is meeting ministers to discuss anti-Semitism following the firebombing of a French Jewish school.
Mr Chirac is holding talks with Prime Minister Jean-Pierre Raffarin and three of his top ministers on Monday before receiving Jewish leaders.
Nobody was injured in the fire at the Merkaz Hatorah school in Gagny, north of Paris, early on Saturday.
Attacks have been linked to Muslim youths angry about Israel's tough policies against Palestinian unrest.
**Highly vigilant***
"The French republic cannot tolerate any anti-Semitic act," Mr Chirac said in a statement. "More than anywhere else, school must be a place of tolerance and respect."
Mr Raffarin added that the government would be "highly vigilant against any anti-Semitic conduct or talk in schools".
Interior Minister Nicolas Sarkozy is taking part in the high-level talks, along with the ministers for justice and education.
Mr Sarkozy, who has taken a tough line against racist and anti-Semitic acts since the centre-right government came to power in May 2002, vowed the unknown arsonists would be severely punished.
France's swift response to the firebombing reflects concern in Paris about charges by Jews abroad that the country's ruling elite are anti-Semitic.
French Jewish leaders reject this, but admit to being worried about continued violence against their community.
