METHOD: National policies related to AAPS were reviewed using data from the Global Information System on Alcohol and Health, following the framework of the WHO Global Strategy to reduce the harmful use of alcohol. The policy review was supplemented with data from corporate annual reports, press releases, four databases of academic literature, market research from Euromonitor International, and news articles.

RESULTS: Four TACs--Carlsberg, Diageo, Heineken, and San Miguel--have been expanding operations in Southeast Asia by setting up new breweries, acquiring local alcohol companies as subsidiaries, and entering into joint ventures. In contrast, policies for regulating AAPS vary across Southeast Asia and range from nonexistent to strong control of AAPS. There is strong control of AAPS in countries with existing legislation ranging from a complete ban (Brunei) to almost comprehensive bans (Indonesia, Myanmar, Laos) and partial bans (Thailand). Nonexistent to weak control of AAPS is observed in the Philippines, Singapore, Cambodia, Malaysia, and Vietnam, which mostly rely on voluntary regulation.
