Ulaanbaatar
Ulaanbaatar, formerly anglicised as Ulan Bator (, , literally "Red Hero"), is the capital and largest city of Mongolia. The city is not part of any aimag (province), and its population was over 1.3 million, almost half of the country's total population. Located in north central Mongolia, the municipality lies at an elevation of about in a valley on the Tuul River. It is the country's cultural, industrial and financial heart, the centre of Mongolia's road network and connected by rail to both the Trans-Siberian Railway in Russia and the Chinese railway system.
Ulaanbaatar
Ulaanbaatar has close ties to cities like Seoul ( from UB), Hong Kong ( from UB), Tokyo ( from UB) and Moscow ( from UB). The Zamyn Uud-Erenhot and Altanbulag-Kyakhta borders are the only places where sustained interaction occurs between Mongolia and its neighbors. Other ports are much smaller. For now Ulaanbaatar remains the main, and almost only, point of contact between Mongolia and its neighbors. Beijing remains the closest global city to Ulaanbaatar. The UB-Peking corridor is served by busy air, rail and road links.In the novel "Alas, Babylon" by Pat Frank, the city was a relocation site for the Soviet leadership. In the novel it had a medium-wave station for communications.
