Vaezi made the remarks referring to Russia’s move on Friday to host a ceasefire talks with the presidents of the warring states of Azerbaijan and Armenia.
"Our region can resolve problems and ensure peace as well as security," Vaezi tweeted adding, "Moscow's talks with the foreign ministers of Azerbaijan and Armenia are a good sign of the independent regional powers' capacities, and Iran is ready to assist and cooperate in the peace and stability process following international law."
Renewed fighting over Karabakh – an ethnic Armenian region of Azerbaijan that broke from Baku's control in a devastating war in the early 1990s – has claimed some 400 lives and forced thousands of people from their homes.
The heavy clashes erupted late last month, with both sides blaming the other for the biggest outbreak in violence since a 1994 cease-fire left the status of Karabakh in limbo.
The region's declaration of independence has not been recognized by any country – even Armenia – and the international community regards it as part of Azerbaijan.
