Trade unions across China have been urged by China's national union chairman to protect employee rights.

Wang Zhaoguo, chairman of the All-China Federation of Trade Unions (ACFTU), made the remarks during a five-day inspection tour to northeast China's Liaoning Province which ended on Sunday.

Wang, a member of the Political Bureau of the Communist Party of China Central Committee and vice chairman of the Standing Committee of the National People's Congress, told local trade unions to implement the collective wage negotiation system "in real earnest" and to determine wage standards in a scientific way.

"This is to ensure that employees can share the rewards of business growth," he said.

He also called for further efforts to enforce the Labor Contract Law, strengthen psychological counseling for employees, and make trade unions more active.

"The trade union's job should be expanded to promote harmonious labor-capital relations and maintain the stability of the labor force and society," he said.

The ACFTU, founded on May 1, 1925, had a membership of 169.94 million, with migrant workers, accounting for 24.1 percent of the total, in 2007.
