Chinese enterprises have made great efforts to promote green development and become more economical and environment-friendly, a Chinese official said Wednesday.

"Chinese enterprises have made enormous efforts to promote technological innovation, clean production, green development and recycling economy, strived to build economical and environment-friendly enterprises," he said.

These enterprises have also constantly focused on product quality, production safety, and protection of the rights and interests of the workers and consumers. That has greatly contributed to China's economic and social development, added Wang, who is also president of the China Entrepreneurs Association.
