The Ministry of Finance announced Monday that the central government has budgeted 5 billion yuan (814 million U.S. dollars) for rewarding air pollution treatment efforts in several regions.

These regions include the municipalities of Beijing and Tianjin, the provinces of Hebei, Shanxi and Shandong, as well as the Inner Mongolia Autonomous Region, according to a ministry statement.
