Foreign Ministers Elmar Mammadyarov of Azerbaijan and Armenia's Vardan Oskanian met this week in London.
Oskanian told RFE/RL's Armenian service that the two presidents will come together in France, probably sometime in early February.
"I also can now confirm that there will be a new meeting between the two presidents because that was also decided at this [London] meeting. And the French side has already handed invitations to both presidents."
Predominantly ethnic Armenian Karabakh seceded from Soviet Azerbaijan in 1988, triggering a war that claimed some 30,000 lives and drove more than 800,000 people from their homes. A truce was signed in 1994, but Armenia and Azerbaijan remain formally at war.
