Official confirmation of France's return to the formula one calendar is now close, Radio Monte Carlo is reporting.
"The French authorities have finally agreed the price with (Bernie) Ecclestone," the report said.
Earlier, when prime minister Francois Fillon said advanced talks with F1 were taking place, he indicated the gap with Ecclestone's demands was about 2 million euros.
RMC said the deal "should be completed next week".
It is expected that the Ecclestone-owned Paul Ricard will share an annually alternating grand prix date with Belgium's Spa-Francorchamps, beginning in 2013.
