This work includes the analysis of the latest trends and key issues in ITAs, building the capacity of developing countries to negotiate and implement investment agreements that can foster sustainable investment, and establishing a platform for universal, inclusive and transparent stakeholder engagement on these issues. International investment agreements (IIAs) are divided into two types: (1) bilateral investment agreements and (2) investment agreements. A bilateral investment agreement (BIT) is an agreement between two countries on the promotion and protection of investments made by investors of the countries concerned in the territory of the other country. The vast majority of AIIs are BITs. The category of contracts with investment rules (TIPs) includes different types of investment agreements that are not NTBs. .
