The Vladivostok remains at the shipyard in Saint-Nazaire, western France
France stopped the sale after the outbreak of the conflict in eastern Ukraine, where Russia is accused of backing separatist rebels.
The Mistral contract was worth ?1.2bn (?843m; $1.3bn). Russia made an advance payment of about ?840m.
The first of two helicopter carriers ? the Vladivostok ? was supposed to be delivered to Russia in November 2014.
?The negotiations are completely finished, everything has already been decided, both the time-frame and the amount,? said Vladimir Kozhin, an aide to Russian President Vladimir Putin.
Western sanctions have been ratcheted up against Russia since March 2014, when the Ukrainian crisis began.
