There are many business organizations and trade councils in China and these may serve as meaningful resources for the jobseeker. Some trade organization and business councils are based outside China and many countries around the world have organizations geared to helping those looking to do business in China. These are also worth a look.

China itself recognizes only one government-sponsored workers’ organization, the All China Federation of Trade Unions (ACFTU). The ACFTU is state-controlled and has a history of failing to represent its members adequately. The ACFTU has about 103 million members. Independent trade unions are illegal in China. As China is now a member of the WTO, pressure is increasing from other countries for China to respond more favorably to worker rights. Although China is also a member of the International Labor Organization (ILO), China has not revised its labor laws to reflect the ILO’s ideology. China does not recognize the rights of workers to establish organizations of their own choice. Those trying to organize workers are usually detained.
