Chamakh's current deal expires at the end of the season and the Morocco international has been offered terms to stay with the French club.
Triaud confirmed there have been no developments regarding Chamakh's future and acknowledged it is up to the front man whether he stays with the French champions.
"There is nothing new on that case so far," Triaud told Le Quotidien du Foot. "Am I confident? I must admit I don't know what to say.
"Our improved contract offer is still valid. Now, it depends on him, rather than on me.
"You will have to ask him the question. It is up to him to make the decision."
