On 17 May 1948, on the third day of Israel's independence, the Soviet Union granted de jure recognition to the State of Israel, becoming only the second country to recognise Israel (preceded only by the United States' de facto recognition) and the first country to grant Israel de jure recognition. The Soviet Union and the other communist states of Eastern Europe (with the exception of Romania) cut diplomatic ties with Israel during the Six-Day War. Relations were restored on 19 October 1991, a few months before the dissolution of the Soviet Union, despite the fact that hostile Arab countries such as Syria also maintain close ties with Russia. Russia is known to supply Syria with weapons. In September 2010, Israel and Russia signed a comprehensive military agreement that will "increase cooperation on combating terrorism" and the proliferation of nuclear weapons. Israeli Defense Minister Ehud Barak met with his Russian counterpart, Anatoly Serdyukov and Prime Minister Vladimir Putin, and signed the agreement during a ceremony in Moscow. The Russian military plans on purchasing additional Israeli unmanned aerial vehicles. Russia previously bought 12 drones from the Israel Aerospace Industries following the war in South Ossetia. Serbia Diplomatic relations between Israel and Serbia's predecessor state, Yugoslavia, were severed for twenty-four years, from 1967 until 1991, when they were officially renewed, by which time Yugoslavia was in the process of disintegration. Diplomatic relations continued when, in April 1992, the two remaining Yugoslav republics, Serbia and Montenegro, formed the Federal Republic of Yugoslavia (renamed to Serbia and Montenegro in February 2003). On 3 June 2006, Montenegro and Serbia dissolved the union. Slovakia Both countries established diplomatic relations in 1993. Israel has an embassy in Bratislava, with its first resident ambassador in Slovakia being Yael Rubinstein. Slovakia has an embassy in Tel Aviv. In May 2008, Slovakian Prime Minister Robert Fico called Ehud Olmert and Shimon Peres for the strengthening of diplomatic relations between Israel and Slovakia. An Israel – Slovakia Chamber of Commerce and Industry also exists to facilitate further economic and business cooperation between the two countries. Slovenia Israel and Slovenia established full diplomatic relations when Israel officially recognized Slovenia on 16 April 1992 and on 28 April 1992 when the countries signed the Protocol establishing diplomatic relations between each other. The Slovenian-Israeli Chamber of Commerce was established in 2010 signifying a strengthening of ties and both countries have discussed bilateral cooperation in business,
