Today, the progress of globalization is minimal and the scale of international trade activities is growing. The deepening integration of the global economy has made international cargo trade more frequent and thus complicating the immunity of contracts. International cargo trade legal disputes often have to take advantage of the legal clash rules, but it is hard to avoid the problem of applying the law due to differences in national legislation. International cargo trade legislation to regulate is badly needed between countries. The relevant provisions of the Convention are one of the important reasons for our analysis and resolution of problems related to the implementation of international commodity trade agreements. Articles 79 and 80 of CISG are the normative provisions on contract exemptions. To facilitate its broad application, the CISG obscures the meaning of some terms and the clause is applicable only after interpretation. The issue of immunity is emerging as a concern for the parties because of the greater risks faced by the parties to international cargo trade than by domestic contracts in China. The CISG is China's most important law on international cargo trade, guiding something quite important. To this end, this paper can not only provide a theoretical basis for solving similar immunity cases through a comparative study on the face of CISG and Chinese Contract Law, but also find a point on the exemption system in Chinese Contract Law and suggest improvements.
