Chinese ethnic minority music is an important part of traditional Chinese culture, holding a unique position and role. The 56 ethnic groups in China have their own music styles and performance forms, forming a diverse and rich ethnic music tradition. With the advancement of the "Belt and Road Initiative", Chinese minority music has gradually gained recognition and increased international dissemination. This paper explores the approaches and impacts of Chinese ethnic minority music dissemination under the "Belt and Road Initiative" context. Through strengthening communication and cooperation with countries and regions along the routes, ethnic minority music can be showcased on a broader stage and engage in dialogue and integration with the music of other countries and regions. The paper also proposes strategies for the dissemination of ethnic minority music, providing references and insights for scholars to further research ethnic minority music and explore the effectiveness of music dissemination strategies and the protection of music. It is hoped that through the dissemination of Chinese ethnic minority music, ethnic cultures can be spread worldwide, providing a strong bridge for cultural exchanges and mutual understanding among people.
