However, Kocharian cautioned that no final agreement is expected.
He was speaking to reporters in the Swedish capital, Stockholm, ahead of a meeting with his Azerbaijani counterpart, President Ilham Aliyev.
The two-day talks in Rambouillet, France, begin on 10 February.
The leaders will discuss the future status of the predominantly ethnic-Armenian Nagorno-Karabakh, which seceded from Soviet Azerbaijan in 1988, triggering a six-year war that ended with a truce. Officially, the two countries are still at war.
In addition to their presence in Nagorno-Karabakh, Armenian troops occupy seven Azerbaijani administrative districts next to the separatist enclave.
