ASIA AND MIDDLE EAST TOURS
The borders of Central Asia are subject to multiple definitions. The most limited definition was the official one of the Soviet Union, which defined Middle Asia as consisting solely of Uzbekistan, Turkmenistan, Tajikistan and Kyrgyzstan. This definition was also often used outside the USSR during this period. Soon after independence, the leaders of the four former Soviet Central Asian Republics met in Tashkent and declared that the definition of Central Asia should include Kazakhstan as well as the original four included by the Soviets. Since then, this has become the most common definition of Central Asia, the land of Five Stans: Uzbekistan, Turkmenistan, Tajikistan and Kyrgyzstan and Kazakhstan. The UNESCO general history of Central Asia defines the region based on climate and uses far larger borders. According to it, Central Asia includes Mongolia, Tibet, northeast Iran (Golestan, North Khorasan and Razavi provinces), central-east Russia south of the Taiga, large parts of China, Afghanistan, Pakistan.
