Senior officials from WIPO, the African Intellectual Property Organization (French abbreviation: OAPI. OAPI, Organisation Africaine de la Propriete Intellectuelle), the African Regional Industrial Property Organization (ARIPO) and 16 African countries and nearly 100 Chinese participants attended the two-day forum.展开更多
