E/C.12/CHN/CO/2 effective strategies to reduce unemployment rates, with special attention to minorities, and in regions where unemployment is most severe. Persons with disabilities 18. The Committee is concerned that, despite the measures undertaken by the State party to promote access to employment and improve the working conditions of persons with disabilities, including through the establishment of the 1.5 per cent employment quota, the high rate of unemployment among persons with disabilities persists and that the existing disparities in relation to wages have not been effectively addressed (arts. 6 and 7). The Committee urges the State party to enhance its efforts to promote effectively the integration of persons with disabilities, especially into the labour market, including by strengthening the effectiveness of the system of job quotas and establishing an efficient enforcement procedure and remedies. The Committee also recommends that the State party take effective measures to improve the working conditions of persons with disabilities, including through establishing an obligation to provide reasonable accommodation in the workplace and introducing the principle of equal pay for work of equal value. The Committee requests that the State party provide disaggregated statistical data on the employment rate of persons with disabilities. Minimum wage 19. The Committee notes that discretionary authority to establish minimum wages is delegated to municipal and provincial governments, and expresses concern about the lack of a transparent system of indexation and adjustment. The Committee is also concerned that in some municipalities and provinces the minimum wage is insufficient to ensure a decent living for workers and their families (art. 7). The Committee calls upon the State party to ensure that an effective and transparent system of indexation and regular adjustment of the minimum wage is established and at a level sufficient to provide all workers and their families with a decent standard of living. Working conditions 20. The Committee is concerned about information on inadequate and unsafe working conditions, including instances of injury and death, the non-signature of labour contracts and insufficient medical and accident insurance, particularly in the private and informal sectors (art. 7). In line with its previous recommendation (E/C.12/1/Add.107, para. 53), the Committee urges the State party: (a) To adopt all necessary measures to ensure just and favourable conditions of work, especially for workers in the private sector; (b) To take measures to regularize the situation of informal sector workers by progressively improving their working conditions and including them in the social security system; (c) To ensure that all categories of workers have access to medical and accident insurance, as well as to adequate compensation for injuries and work-related diseases; (d) To establish an effective and independent inspection mechanism for monitoring the conditions of work and provide it with adequate human and financial resources; 6
