Russia, which holds the world's third-biggest foreign exchange reserves, is "concerned" about economic woes in Europe and the U.S., President Dmitry Medvedev's chief economic aide said Monday.

Arkady Dvorkovich said he was concerned about Europe's economic challenges, saying it is "not clear" who will make the final decisions with regard to the euro-zone debt crisis.

Dvorkovich said several days ago that Russia is likely to continue cutting the share of its reserves invested in U.S. debt as Washington faces large budget deficits and tries to revive a lukewarm economic recovery. Spain recently asked Russia to purchase its debt, according to Russia's finance minister.

Medvedev's aide also said Monday the oil price shouldn't determine the pace of reform in Russia and that new political forces are emerging on the left and right that will create a more balanced political system. Russian reforms should continue regardless of who is president next year, he said.

Dvorkovich confirmed that the sale of a state-held stake in gas giant OAO Gazprom (GAZP.RS) is not under discussion.
