Russia and Italy on Friday signed an agreement that will allow military material destined for Italian troops deployed in Afghanistan to transit Russian territory.
Russian President Dmitry Medvedev said the deal was Moscow's contribution to resolving the complicated problems in Afghanistan.
Mr. Medvedev was speaking in the mountain resort town of Krasnaya Polyana where he was hosting Italian Prime Minister Silvio Berlusconi.
Russian news agencies said the agreement will allow the transit of both civilian and military cargo, including weapons and ammunition.
The meeting of the two European leaders took place in the shadow of the latest barrage of released U.S. diplomatic cables that revealed less than flattering U.S. evaluations of their personalities.
One cable reportedly described Mr. Berlusconi as "profiting personally" from a close relationship with Russian Prime Minister Vladimir Putin.
Mr. Berlusconi on Friday dismissed those claims, while Mr. Medvedev said the classified cables published on the WikiLeaks site just served to show the cynicism of U.S. foreign policy.
The two leaders also signed a series of bilateral memoranda, including a deal between Italy's Enel utility and Russia's power company Inter RAO.
