The central government is encouraging the use of world-leading technologies and materials in the construction of Beijing's subcenter in Tongzhou district to make it more eco-friendly.

Beijing's subcenter will be required to meet the standard of a world-class livable city, providing a good environment, cultural elements and convenience to residents, the Political Bureau of the Central Committee of the Communist Party of China announced after a meeting on Friday.

According to the plan, the same principles should also be used in developing regional cooperation between Beijing and Tianjin municipalities, and Hebei province.
