This paper focuses on the activities, revenue flows and governance of Myanmar’s extractive-industry state-owned economic enterprises (SEEs). As Myanmar seeks to build more modern and open oil, gas and mining industries, SEEs active in these sectors will play a critical role. Enhancing the effectiveness of these SEEs will be an important goal of Myanmar’s continued economic reform. The aim of this research is to help governmental and non-governmental stakeholders within Myanmar assess key challenges surrounding the country’s oil, gas and mining SEEs. It builds on preliminary information-gathering within Myanmar and NRGI’s global research on the governance of state-owned enterprises.
