Not until October, 1939, did Eurasia, through the medium of the newly formed Sino-Soviet Aviation Company, open a new service. It ran from Chungking to Ha-mi, whence, through the cooperation of Sinkiang authorities and the Soviet People's Aviation Company, it was continued via Tihwa, I-ning, and Alma-Ata (the latter over the border, in Soviet Kazakhstan) to Moscow. The trip from Chungking across Sinkiang to Alma-Ata totals about 2,584 miles and has become extremely important in United Nations mail and transport services.
