Wal-Mart chiefs have promised to help China's top trade union authority establish unions in all of its outlets across the country.

Wal-Mart executives made the commitment during visits to branches of the All-China Federation of Trade Unions (ACFTU) in Shenzhen and Nanjing, where altogether five Wal-Mart unions have been formed.

Ye Chunxiu, district manager of the U.S.-based retail chain's Jiangsu stores, said "Wal-Mart China hopes to strengthen communication with the ACFTU and our employees. We will cooperate closely with the ACFTU in setting up trade unions in all the 60 Wal-Mart outlets in China."

Six trade unions have been established at Wal-Mart outlets in China since July 29: four in Shenzhen and one each in the eastern city of Nanjing and the southeastern city of Quanzhou.
