This paper outlines the current state of food labelling policy in the Southeast Asia region, describes observed industry interference tactics, and provides recommendations for how governments in Southeast Asia can address this interference to deliver best-practice nutrition labelling to improve diets at the population level. The experiences of four focal countries – Malaysia, Thailand, the Philippines, and Viet Nam – are highlighted to provide insights into the range of industry tactics that are serving to prevent optimal food labelling policies from being developed and implemented.
