As a leader in digital cultural exports，Chinese online micro-dramas，together with online literature and games，constitute a powerful driving force for Chinese culture to go overseas. In recent years，its internationalization process has welcomed unprecedented opportunities and faced many challenges. The opportunities lie in the huge potential user base，increasing willingness to pay and retention rate，and rapid expansion into international markets，especially in Southeast Asia，while the rise of platforms such as ReelShort has also shaped a new competitive landscape. However，cultural differences，audience demand adaptation，culture clash risk，content regulation obstacles，technical bottlenecks and brand building problems have added complexity to the road to overseas. In order to cope with the challenges，it is necessary to start from the aspects of content innovation and diversification，technology-driven dissemination，international cooperation and talent cultivation，and strengthening the awareness of law and ethics，to deeply explore the needs of global audiences，to rely on platforms and big data analysis，to promote transnational cooperation，to strengthen the protection of intellectual property rights，and to promote the sound development of the international dissemination of China’s microshort dramas.
