This study explores feasibility of regional rice market integration by examining the impacts on production and trade, with a specific focus on the adjustment impacts for rice producers. It seeks to set out policy measures required to better integrate the rice markets of Association of Southeast Nations (ASEAN) countries and the role that trade policy can play to help the agricultural sector adjust to pressures created from freer trade in rice within this region. While regional rice market integration can deliver more rice at lower prices to the regions consumers, this study finds significant adjustments to the rice sectors will be required in Indonesia, Malaysia, and the Philippines. However, opportunities through lowering tariff barriers with existing key trading partners of free trade agreements has the scope to create more employment and value adding opportunities in all agricultural sectors to offset the losses from regional rice market integration. The study suggests a number of measures are necessary to build trust in regional markets to allow rice market integration to take place. This includes an agreement to ban export restrictions. Furthermore, while broader trade reforms will help create new opportunities for agricultural sectors across the ASEAN region, flanking policies and investments in the enabling environment are still required for the sectors to take full advantage of these opportunities.
