The proposed agreement at the summit from November 30 is expected to be vigorous and to become a milestone for global climate governance, Zhang said here at an annual meet of the China Council for International Cooperation on Environment and Development.
China will actively promote international communication in the area and try hard to undertake its due international obligations, which are also part of the nation's efforts to promote green development and improve the environment, according to Zhang, the council's chairman.
It will optimise the exploitation of land resources, forcefully promote green and sustainable development featuring safe, clean, low-carbon and highly-effective energy and improve laws on environmental protection, Zhang said.
