TBILISI (Reuters) - Georgia's new premier said on Wednesday his government would stick to the ex-Soviet republic's pro-Western course but also try to mend relations with Russia, Tbilisi's old Soviet master and adversary in a five-day war in 2008.
Parliament confirmed Irakly Garibashvili and his cabinet by a vote of 93-19, completing a political transition that has ended almost a decade of dominance by former president Mikheil Saakashvili, who avidly sought integration with the West.
The South Caucasus country of 4.5 million, which is crossed by pipelines that carry Caspian Sea oil and gas to Europe, has warm ties with Washington and hopes eventually to sign an association agreement bringing it closer to European Union.
A more distant goal is membership in the NATO defense alliance, a prospect Russia strongly opposes.
"Georgia's aspiration for EU and NATO membership is the only right way for us ... We will continue to move towards Europe step by step," Garibashvili, 31, said in an address to parliament before the vote. "The government will also try to overcome a crisis in relations with Russia."
Garibashvili takes over from Bidzina Ivanishvili, a billionaire who became prime minister after leading an opposition coalition to victory over Saakashvili's party in an October 2012 parliamentary election.
Ivanishvili, who entered politics just two years ago after a business career in which he made a fortune estimated at $5.3 billion, made efforts to maintain good ties with the West while improving them with Moscow.
Ivanishvili stepped down after ally Georgy Margvelashvili was sworn in as president on Sunday, saying the departure of Saakashvili, a bitter rival, meant his job was done.
He handed Garibashvili, a former interior minister who is also a close ally, the task of treading a political tightrope between Russia and the West.
Ivanishvili, whose party's dominance of parliament enabled him to eclipse Saakashvili politically over the past year, succeeded in opening the Russian market for Georgian wine, mineral water and fruit after bans imposed in 2006.
But Georgian-Russian tensions still run high five years after the war over two Moscow-backed breakaway regions of Georgia in August 2008, and diplomatic relations have not been restored.
Under changes to the constitution that transfer many of the president's responsibilities to the prime minister, Garibashvili becomes the country's most powerful politician.
He is in charge of foreign as well as economic policy in a nation where poverty is a problem and growth has slowed after years of robust expansion.
Gross domestic product increased just 1.5 percent in the second quarter of this year, down from 8.2 percent in the same period a year ago.
Underscoring persistent political divisions, lawmakers from Saakashvili's party did not vote for the new cabinet, in which the only newcomer is Interior Minister Alexander Chikaidze.
