A more thorough explanation:

The International Law Commission is a group of experts in international law that was created by the United Nations in 1947. Its main purpose is to encourage the development and codification of international law.

The Commission has drafted many important treaties that have become binding treaty law. For example, the Vienna Convention on the Law on Treaties is one of the treaties that the Commission has drafted. This treaty sets out the rules for making and interpreting international agreements.

The Commission's work helps to ensure that there is a clear and consistent framework for international relations. By creating treaties and other legal instruments, the Commission helps to promote peace, security, and cooperation among nations.
