A witness travelling with Saakashvili said uniformed South Ossetians fired the warning shots after the convoy came within 30m of the de facto border.
No one was hurt and the convoy turned back. Officials travelling with visiting Polish President Lech Kaczyinski were quoted as saying shots were heard from an unknown direction.
"We were travelling along a mountain road in the direction of Ossetia," Presidential Minister Michal Kaminski was quoted as saying by the Polish PAP agency.
"The cavalcade did not reach its destination and now we are returning to Tbilisi. We heard shots, we do not know what happened."
Russia intervened in Georgia in August to repel a Georgian bid to retake breakaway South Ossetia from pro-Moscow separatists.
