Although Hedin's research was taboo in Germany and Sweden because of his conduct relating to Nazi Germany, and stagnated for decades in Germany, the scientific documentation of his expeditions was translated into Chinese by the Chinese Academy of Social Sciences and incorporated into Chinese research. Following recommendations made by Hedin to the Chinese government in 1935, the routes he selected were used to construct streets and train tracks, as well as dams and canals to irrigate new farms being established in the Tarim and Yanji basins in Xinjiang and the deposits of iron, manganese, oil, coal and gold discovered during the Sino-Swedish Expedition were opened up for mining. Among the discoveries of this expedition should also be counted the many Asian plants and animals unheard of until that date, as well as fossil remains of dinosaurs and other extinct animals. Many were named after Hedin, the species-level scientific classification being "hedini". But one discovery remained unknown to Chinese researchers until the turn of the millennium: in the Lop Nur desert, Hedin discovered in 1933 and 1934 ruins of signal towers which prove that the Great Wall of China once extended as far west as Xinjiang.
