Perlas was the chief negotiator for a network of national networks, which involved 5000 organizations, that successfully stopped the agenda of radical and one sided liberalization in the Asia Pacific Economic Cooperation or APEC. He successfully introduced strong sustainable development language in the Leaders and Ministerial Declarations in APEC, and constrained the Individual Action Plan of the Philippines to abide by sustainable development principles. The successful negotiations prevented the premature exposure and economic decline of 3 million Philippine rice farmers to subsidized and artificially cheap rice coming from other countries.
