China is also a member state to the Madrid Protocol. Thus, the extension of an international registration of a trademark via the Madrid System is possible for this country.

The applicant shall indicate on the application the class of goods and describe the goods with which the mark is used, based on the prescribed schedule of classes of goods, and shall file an application, meanwhile,the applicant can apply the same trademark for goods in different classes with an application.
