Russia's Foreign Minister Sergey Lavrov is in Turkey for talks on the Georgian crisis and a trade dispute.
Turkey has threatened to retaliate against new Russian import controls that are seen as an attempt to punish Turkey for allowing US warships carrying aid to reach Georgia.
The extra import checks for Turkish goods have resulted in hundreds of Turkish trucks being held up at Russian border posts.
Lavrov and Turkey's Foreign Minister Ali Babacan are also to discuss a Turkish plan for a regional group to stabilize the Caucasus region following war between Russia and Georgia.
The group would include Turkey and four nearby Caucasus nations: Russia, Georgia, Azerbaijan and Armenia.
