非违约之诉是WTO的一项特殊的诉讼机制。由于GATT/WTO的有关规定并未就非违约之诉的实体规则———构成要件———作出明确规定,使得该机制的设立和启动招致争议,也使之在适用上具有一定的模糊性。我国作为一个发展中的贸易大国,应当对非违约之诉机制进行深入研究。如此既能最大限度地避免其他国家对我国提起非违约之诉,又能合理利用该机制以保障和维护我国的利益。 The non-default complaint is a special litigation mechanism in the WTO. Since the relevant provisions of the GATT / WTO do not make any explicit stipulations on the substantive rules of the non-default complaint --- the constitutional requirements, the establishment and commencement of the mechanism have caused controversy and made it ambiguous in its application . As a large developing country, China should conduct an in-depth study on the mechanism of non-breach of contract. In this way, we can try to avoid other countries from suing China for non-breach of contract, and make reasonable use of this mechanism to safeguard and safeguard our interests.
