The registration authorities review relevant investment application materials in form. When foreign investors or foreign-invested enterprises invest in sectors not listed in the Negative List, the principle of equal treatment for domestic and foreign investment applies to registration. When foreign investors or foreign-invested enterprises invest in sectors with restrictive requirements from the Negative List for matters such as the proportion of capital contribution and the nationality of the legal representative (main responsible person), registration shall be completed in accordance with the law if the restrictive requirements have been satisfied. In cases where competent industrial regulatory departments have granted permits for relevant business operation in accordance with the law prior to registration, the registration authorities do not need to examine again whether the restrictive requirements of the Negative List have been satisfied. It is crucial to note that registration is not permitted when foreign investors or foreign-invested enterprises invest in sectors prohibited by the Negative List.
