Investment law refers to the legal framework that governs the rights and obligations of investors and states in international investments. It includes treaties, agreements, and regulations that protect foreign investments from unfair treatment, expropriation, and discrimination. These laws aim to create a stable environment for investors, encouraging economic growth and development. Additionally, investment law often involves dispute resolution mechanisms, such as arbitration, to address conflicts between investors and host countries. Organizations like the International Centre for Settlement of Investment Disputes (ICSID) play a crucial role in facilitating these processes, ensuring that both parties can seek fair resolutions.
