E/C.12/VNM/CO/2-4 Residential registration system 14. The Committee expresses concern at the discriminatory impact of the residential registration system (hô khâu) on access by internal migrants to social services, and the enjoyment of other rights, such as housing rights and the right to water and sanitation (art. 2, para. 2). Recalling the constitutional guarantee of freedom of movement and residence within the country, the Committee urges the State party to ensure that change of residence, even temporarily, does not affect the enjoyment of economic, social and cultural rights. In particular, the Committee recommends that the State party immediately lift the requirement of residential registration for accessing social benefits, housing, services, such as water and sanitation, and school registration, and that it modify the current residential registration system to make it fully compatible with human rights standards. Persons with disabilities 15. The Committee notes with concern that persons with disabilities are discriminated against in the enjoyment of several rights, such as the right to education and the right to work, in spite of the adoption of the 2010 Law on Persons with Disabilities. Moreover, the Committee is concerned that the new package of tax exemptions and other benefits for enterprises where persons with disabilities make up at least 30 per cent of the personnel favours the creation of segregated enterprises (art. 2, para. 2). The Committee recommends that the State party: (a) Allocate sufficient resources for the implementation of the 2012–2020 National Action Plan on Disability, especially with regard to accessibility and the provision of reasonable accommodation, particularly in rural areas; (b) Undertake awareness-raising campaigns to eliminate cultural barriers and prejudices against persons with disabilities; (c) Actively recruit persons with disabilities in the public sector and reinstate the quota system, including in the private sector; (d) Put in place an effective system of assessing the enjoyment of economic, social and cultural rights of persons with disabilities; (e) Expedite the ratification of the Convention on the Rights of Persons with Disabilities. Discrimination against women 16. The Committee notes with concern that, owing to their role as main caregivers in the family, women in the State party work primarily in the informal economy where working hours are more flexible. The Committee is further concerned at measures taken by the State party that de facto perpetuate this discriminatory situation, such as the maintenance of the provisions on the care-giving role of women in the new Law on Marriage and Family and the gender-biased training plans on skills such as sewing and knitting (art. 3). The Committee recommends that the State party: (a) Amend all legislative provisions which are discriminatory to women, such as those in the Law on Marriage and Family, as well as the different retirement ages for men and women; 4
