resolve the Tajikistan and Afghanistan conflicts, both of which it sees as posing threats to its own stability. Previously close to Washington (which gave Uzbekistan half a billion dollars in aid in 2004, about a quarter of its military budget), the government of Uzbekistan has recently restricted American military use of the airbase at Karshi-Khanabad for air operations in neighbouring Afghanistan. Uzbekistan was an active supporter of U.S. efforts against worldwide terrorism. The relationship between Uzbekistan and the United States began to deteriorate after the so-called "colour revolutions" in Georgia and Ukraine (and to a lesser extent Kyrgyzstan). When the U.S. joined in a call for an independent international investigation of the bloody events at Andijan, the relationship further declined, and President Islam Karimov changed the political alignment of the country to bring it closer to Russia and China. In late July 2005, the government of Uzbekistan ordered the United States to vacate an airbase in Karshi-Kanabad (near Uzbekistan's border with Afghanistan) within 180 days. Karimov had offered use of the base to the U.S. shortly after 9/11. It is also believed by some Uzbeks that the protests in Andijan were brought about by the UK and U.S. influences in the area of Andijan. This is another reason for the hostility between Uzbekistan and the West. Uzbekistan is a member of the United Nations (UN) (since 2 March 1992), the Euro-Atlantic Partnership Council (EAPC), Partnership for Peace (PfP), and the Organization for Security and Co-operation in Europe (OSCE). It belongs to the Organisation of Islamic Cooperation (OIC) and the Economic Cooperation Organization (ECO) (comprising the five Central Asian countries, Azerbaijan, Iran, Turkey, Afghanistan, and Pakistan). In 1999, Uzbekistan joined the GUAM alliance (Georgia, Ukraine, Azerbaijan and Moldova), which was formed in 1997 (making it GUUAM), but pulled out of the organisation in 2005. Uzbekistan is also a member of the Shanghai Cooperation Organisation (SCO) and hosts the SCO's Regional Anti-Terrorist Structure (RATS) in Tashkent. Uzbekistan joined the new Central Asian Cooperation Organisation (CACO) in 2002. The CACO consists of Uzbekistan, Tajikistan, Kazakhstan, and Kyrgyzstan. It is a founding member of, and remains involved in, the Central Asian Union, formed with Kazakhstan and Kyrgyzstan, and joined in March 1998 by Tajikistan. In December 1994 Uzbekistan applied for the World Trade Organization membership and received an observer status to start the accession process. The Working Party on the Accession of Uzbekistan to
