Traditional international law

Traditional domestic law forms international treaty law through concluding treaties on the basis of bilateral or multilateral negotiations, or gradually forms international customary law through legal confirmation of international practices. These are the two most important traditional international laws. However, international environmental law is practical and urgent, and the interests of different countries and regions are quite different, so it is unlikely to form a relatively developed international treaty law or international customary law in a short time. Therefore, it is very important to formulate non-legally binding "soft law" documents such as declarations and guiding principles. Although the rules produced by these documents are not binding, they have the function of advocacy and suggestion, and can be the forerunner of the rules of international law in the traditional sense.
