Ice Breeze outpointed British challenger Call To Mind to claim top honours in the Qatar Prix Chaudenay at Chantilly.
Frankie Dettori sported the royal colours of the Queen aboard the William Haggas-trained Call To Mind, who was a leading contender for this one-mile-seven-furlong Group Two having impressed in a Goodwood Listed event at the end of August.
The three-year-old raced on the speed throughout and managed to see off Darbuzan in the final furlong, but Pascal Bary's Ice Breeze came through a gap on the rail to get up and score narrowly in the hands of Vincent Cheminaud.
Bary said: "We beat the Queen! He was given a masterful ride, but I think our horse was a little bit better than Dettori's horse.
"I think this horse can be a very good stayer next year. I was quite confident he would run a good race today.
"I think for this year he will be finished now and we will wait for the spring. He will be a nice horse for the Prix Vicomtesse Vigier and maybe the Gold Cup (at Royal Ascot)."
The Juliet Rose struck gold in the Qatar Prix de Royallieu for the second year in succession.
Nicolas Clement's filly, who was making just her second appearance of the season, was sent straight to the lead by Stephane Pasquier and although both Kitesurf and Listen In threw down strong challenges in the straight, The Juliet Rose clung on grimly to scoop Group Two honours once again.
The daughter of Monsun is now under consideration for the Qipco British Champions Fillies & Mares Stakes at Ascot on October 21.
Derek Brugman, racing manager for Markus Jooste, in whose silks The Juliet Rose runs, said: "She's had a quiet season and might be fresh enough to go for the race at Ascot.
"Obviously it all depends how she pulls out of this, but she gets a mile and and a half very well and is suited by soft ground."
The British challengers were out as luck as Corine Barande-Barbe's Garlingari came home in front in the Qatar Prix Dollar.
Harry Dunlop's Robin Of Navan made much of the running in the 10-furlong affair before fading late on, while the Chris Wall-trained First Sitting - a Group Three winner in France in August - was disappointing under Dettori.
Sylvester Kirk's Salouen fared best of the British-trained trio, finishing off strongly to grab third, but was unable to reel in Garlingari, who galloped all the way to the line to score decisively.
Winning jockey Pasquier was completing a Group Two double following his earlier success aboard The Juliet Rose.
Barande-Barbe is best known for training the hugely popular Cirrus Des Aigles, who claimed this race three times during a stellar career that saw him win 22 races including the Champion Stakes at Ascot and the Coronation Cup at Epsom.
She said: "If you go to Cirrus' Facebook page you will see that he sent Garlingari lots of kisses and good luck.
"This is a perfect day. He is very tough and very genuine and is from a good family.
"He might go to Hong Kong, if he gets an invite. I'm very proud."
