Geographical indications (GIs), signs used on products that identify their geographical origin and special quality or reputation, are atypical intellectual property. The conflicts of interest between the New World and Old World and the diversity of legal regimes have obstructed the international harmonization of GI protection. Neither the Lisbon Agreement nor the TRIPS Agreement have been able to establish a widely accepted international GI registration or protection system. Though the Geneva Act has remarkably improved the treaty regime of GIs, the different approaches of the European Union and United States still seem irreconcilable. This article examines the Chinese dual GI system from a treaty perspective and explores the common functions of GIs and Trademarks, concluding that China's Trademark Law can ensure GI protection that is compliant with the TRIPS Agreement and the Geneva Act. The Chinese solution can be a reference for other countries which protect GIs with a trademark system.
