France is not working with Germany or other countries on a support package for Greece which is managing to handle its problems on its own, a French government source said on Thursday.

"I am not aware of a support plan. There is not a plan. We're not discussing one (with Germany or others)," the source told Reuters.

"They are managing themselves. They are finding financing support on the market. There is no plan for a support plan. We are not working on one."

Le Monde newspaper said earlier that euro zone countries were studying ways of helping Greece resolve its budget problems.
