This chapter examines the legal frameworks for investment protection and dispute resolution that apply to investors in Indonesia. It focuses on several core investment policy issues – the non-discrimination principle, protections for investors’ property rights and mechanisms for resolving investment disputes – under Indonesian law and Indonesia’s investment treaties. It also addresses the government’s recent policy approaches to data protection and cybersecurity, tackling corruption and public sector reforms. It takes stock of recent achievements, identifies key remaining challenges and proposes recommendations to address them. In terms of investment treaty policy, this chapter provides an overview of Indonesia’s investment treaties, analyses the main substantive protections and investor-state dispute settlement provisions in these treaties and identifies considerations for possible policy reforms.
