Utilizing underground spaces

Subterranean projects to ease traffic congestion, aid military defense and provides malls and parking lots

The use of urban underground spaces will be expanded to ease the pressure on land, according to a recent regulation.

By 2020, at least half of China's cities should complete the planning and approval process for developing underground spaces, according to a regulation released by the Ministry of Housing and Urban-Rural Development on June 28, meaning at least 160 cities will develop and enhance them.
