A typical bit begins with a preamble that describes the general intent of the agreement and the provisions relating to its scope. This is followed by a definition of keywords that clarifies, among other things, the meanings of “investment” and “investor.” The ILO then addresses issues related to the admission and installation of foreign investment, including standards for the treatment of foreign investors (minimum standard of treatment, fair and fair treatment, total protection and security, questioning and national treatment most prized). Free transfer of funds across national borders as part of a foreign investment is generally regulated in the ILO. In addition, the ILOs address the issue of expropriation or damage to an investment and determine the amount and manner in which the investor should pay compensation in such a situation. They also set the level of protection and compensation that investors should expect in the event of war or unrest. Another key element of the ILO is the settlement of disputes between an investor and the country in which the investment was made. These provisions, often referred to as investor-state dispute settlement, generally refer to the forums that investors can use to set up international arbitration tribunals (. B for example ICSID, UNCITRAL or ICC) and how this relates to proceedings before the national courts of the host countries. As a general rule, the ILO also contains a dispute settlement clause between the state and the state. Finally, ILOs generally refer to the contract timetable, clarify how the agreement is renewed and terminated, and determine the extent to which investments made prior to the conclusion and ratification of the treaty are covered.  One of the main organizations dealing with the development dimension of AI is the United Nations Conference on Trade and Development (UNCTAD), which is the United Nations single window for issues related to IZURis and their development dimension. The organization`s IDU program supports developing countries in their efforts to participate effectively in the complex investment regulatory system. UNCTAD provides capacity-building services, is widely known for its analysis of research and policy on IDU, and is an important forum for intergovernmental discussions and consensus building on issues related to international investment law and international development.
