While prostitution controls have been relaxed at a local level, there is no impetus for legalisation at the central government level. Importantly, legalisation does not have much public support. Given the underdeveloped nature of the Chinese economy and legal system, there is an argument that legalisation would further complicate the already difficult task of establishing the legal responsibility for third-party involvement in forced prostitution and the traffic in women. Surveys conducted in China suggest that clandestine forms of prostitution will continue to proliferate alongside the establishment of legal prostitution businesses, because of social sanctions against working or patronising a red-light district. Problems associated with female employment also limit the effectiveness of legalisation. These include the lack of independent trade unions, and limited access of individuals to civil redress with regard to occupational health and safety issues.
