BEIJING -- Chinese top political advisor Yu Zhengsheng on Wednesday urged non-public sectors in the country's economy to grasp new development opportunities arising from deepened reforms.

Addressing a meeting of professionals in non-public economic development in Beijing, Yu said the upcoming Third Plenary Session of the 18th Communist Party of China (CPC) Central Committee will study how to "comprehensively deepen reforms."

Non-public sectors will enjoy new opportunities as deepening reform is set to remove systematic obstacles and give more play to the market in resource distribution, said Yu, chairman of the National Committee of the Chinese People's Political Consultative Conference.

China will establish fair market circumstances and improve laws and regulations, so as to preserve justice in fulfilling rights and competition and tackle problems with legal means, said Yu, who is also a Standing Committee member of the Political Bureau of the CPC Central Committee.

He said that the non-public sectors have grown from nothing to a necessity in China since the launch of reform and opening up, and that they will remain a long-term strategy.

Yu also voiced expectation that professionals in the non-public sectors will help realize sustainable development and provide products and services with high quality and efficiency.
