Excerpt from an article in the journal "Popular Mechanics" about the Chinese space program:
According to Chief Designer of Chinese manned spacecraft Zhou Jiangping, the government has allocated 15 billion yuan ($2.35 billion) for the construction and launch of the Tiangong-1 target module and the flight to the station of three spacecraft. That is, three times smaller than the legendary Russian road Adler-Sochi, which is 48 km long. Something money was enough.
