蒙古國Choir-Sainshand公路項目

Mongalia Choir-Sainshand Highway Project

蒙古歷史上第一次建立一條適應(yīng)各種氣候的公路，跨度從北與俄羅斯的交界到南與中國的交界，是蒙古國的“千禧之路”。

For the first time in Mongolia’s history, a road adapted to various climates has been built, which spans from the junction of Russia in the north to the junction China in the south.
