XETDZ enjoys a convenient transportation system, connected by the Xining-Lanzhou expressway and running through by two main roads, the broadest in the city. It is 4 kilometers from the railway station, 15 kilometers from Xi'ning Airport — a grade 4D airport with 14 airlines to cities such as Beijing, Guangzhou, Shanghai, Chengdu and Xi'an. Xining is Qinghai province's passage to the outside world, a transportation center with more than ten highways, over 100 roads and two railways, Lanzhou-Qinghai and Qinghai-Tibet Railways in and out of the city.
