"Those who think that Georgia has reoriented to the Abkhazian direction are mistaken," Mikhail Mindzayev said.
"This temporary lull on our direction is illusory," he said adding that Georgia was seriously preparing for the use of force.
The minister said South Ossetia was ready for such developments.
"But South Ossetian authorities will make every effort not to yield to provocations of the Georgian side," he said.
Mindzayev said masked and uniformed men claiming that they were representatives of the Georgian police were currently stopping all cars on Georgia-controlled roads in South Ossetia.
South Ossetia and Abkhazia declared independence from Georgia following the collapse of the Soviet Union in 1991, bringing bloody conflicts to the region. Russia mediated ceasefire agreements between the sides, and Russian peacekeepers have been deployed in the conflict zones ever since.
