In South East Asia there is sensitivity to international law intruding on domestic sovereignty; a patchy tradition of constitutional democracy; and the central vehicle for international engagement, ASEAN, largely eschews binding norms. A sister panel explored how ASEAN had reconfigured systems of administration around a model of the investee State. This panel explores the way in it has also created an ‘ASEAN‘ imaginary look to each other and international norms in decision-making within their territories. This happens in emergent fields of ASEAN policy, such as e-commerce; regulatory fields which mimic ASEAN regulatory policy-making, such as the environment, and more sensitive fields such as human rights by institutional actors displaced by ASEAN. The possibilities for transplants not only varies but even where these norms are adopted in formally identical manners, they are subject to a domestic constitutional economy, with its own patterns of contestation and meaning.
