Russia will take military and other steps along its borders if ex-Soviet Ukraine and Georgia join NATO, Russian news agencies quoted the armed forces` chief of staff as saying on Friday, according to Reuters.
"Russia will take steps aimed at ensuring its interests along its borders," the agencies quoted General Yuri Baluyevsky as saying. "These will not only be military steps, but also steps of a different nature," he said, without giving details.
Russia is fiercely opposed to NATO plans to grant membership to ex-Soviet Ukraine and Georgia, saying such a move would pose a direct threat to its security and endanger the fragile balance of forces in Europe.
Russian Foreign Minister Sergei Lavrov said earlier this week that Moscow will do everything it can to prevent the two countries, run by pro-Western governments, from becoming NATO members.
President Vladimir Putin has said that if NATO military installations ever appear in Ukraine, Moscow would have to target its missiles at the country.
At a summit in Bucharest this month, NATO members turned down requests from Georgia and Ukraine to be granted a Membership Action Plan, which would have set them on the road to membership.
But under pressure from Washington, one of the strongest advocates of enlargement in the alliance, NATO gave a commitment that the two countries would be allowed to join eventually.
Russian news agencies quoted Baluyevsky as telling reporters that it was premature to talk about Georgia and Ukraine joining NATO anytime soon. "This is not the end of the day," he said. "We will live and see."
