This Review was jointly conducted to inform preparations of country delegations for the UN General-Assembly High Level Meeting on AIDS, 6-8 June 2016 in New York. It highlights significant examples of progress in removing legal and policy barriers to accessing HIV services since 2012. Data for this report is based on country responses from two regional surveys – conducted in January 2015 and February 2016 – from the following countries: Afghanistan, Bangladesh, Bhutan, Cambodia, China, Cook Island, Federated States of Micronesia, Fiji, India, Indonesia, Lao PDR, Mongolia, Myanmar, Nauru, Nepal, Pakistan, Palau, Papua New Guinea, the Philippines, Samoa, Thailand, Vanuatu and Viet Nam. It also draws from a desk review of data reported from countries on these legal and policy reviews and consultations, and related developments in the legal and policy environment for HIV responses in Asia and the Pacific. The Report greatly benefited from review and inputs during the drafting phase from government representatives, civil society organizations, UNAIDS and UNDP country offices, ESCAP, and other development partners.
