The warning came from a high-ranking source and was published by RIA Novosti news agency. It comes after France missed a mid-November deadline for handing over the first of the amphibious assault ships to Russia.
"We are preparing for different scenarios. We are waiting until the end of the month (the fulfillment of Mistral deal), then we will make serious claims," the source said on condition of anonymity.
According to the source, experts are currently analyzing possible damage to Russia if the deal is not fulfilled, and the estimated sum will be made public, RT reported.
"This amount (of compensation) will not be secret," the source added.
The veiled threat prompted reaction from French leadership.
"Today, the conditions to deliver the Mistral aren't there," Prime Minister Manuel Valls told reporters. "France honors its contracts, but France is a nation that counts, wants peace in Ukraine and that makes sovereign decisions without anybody from outside dictating how it acts."
The minister didn’t specify why he considered the terms of a contract duly signed as a form of dictatorship.
It appears that France is trying to buy more time by neither breaking the contract in non-ambiguous terms nor delivering on it. Another Russian source close to Moscow's international defense cooperation told RIA Novosti that France has not yet withdrawn its invite for the delivery ceremony of the vessel.
”The French are keeping silent. They invited us (to the ceremony), but haven’t withdrawn their invitation yet. (We haven’t received) any official address (from them),” he added.
On Thursday, French Defense Minister Jean-Yves Le Drian said Paris hasn’t yet fixed a date for delivery of the first of two Mistral helicopter carriers to Russia (scheduled for November 14).
