The Committee urges the State party to acknowledge that children of Vietnamese origin are subject to discrimination and to take all necessary measures to address their situation and ensure that they have effective access to birth registration, identity documents, public education and health care services. The Committee also urges the State party to provide information in its next periodic report on the measures taken to end discrimination against children of Vietnamese origin and to prevent sexual exploitation and abuse of women and girls belonging to this community.

The Committee calls upon the State party to promptly submit its initial reports on the implementation of the Optional Protocols to the Convention on the Rights of the Child.

I. Cooperation with regional and international bodies 82.

The Committee recommends that the State party take all appropriate measures to ensure that the present recommendations are fully implemented, inter alia, by transmitting them to the members of the Government, Parliament, Provincial Councils and other local authorities, when applicable, for appropriate consideration and further action. 84.
