中国与越南地理相邻，文化相似，文字相通，为中医药在越南的传播提供了便利条件。明清时期，特别是郑和下西洋以来，中医药在越南的传播和交流规模空前。朝贡政策下的中药材贸易在明清时期较为活跃，成为中越贸易往来的重要内容；中医学的辨证论治思想、针灸诊疗技术和温病学说在越南得到传承和发展，形成了与越南气候等因素相适应的诊疗方法和用药思想；在明清政府的影响下，越南的医疗卫生体系不断完善，中医学成为越南医学教育的重要内容；中医药典籍对越南的传统医学思想、药物记载方式产生了深远影响。这不仅促进了中医药文化交流，完善了越南医学理论体系，也为当今中医药在顶层设计、传播路径、文化认同、国际教育模式等方面的多模态国际传播提供了借鉴。

China and Vietnam are geographically adjacent,culturally similar and literally interlinked,which provides convenient conditions for the dissemination of traditional Chinese medicine(TCM) in Vietnam. During the Ming and Qing Dynasties,especially since ZHENG He's voyages,the spread of TCM in Vietnam and mutual communication were unprecedented. The trade of Chinese medicinal materials under the tributary policy was relatively active during the Ming and Qing Dynasties,becoming an important part of Sino-Vietnamese trade exchanges. The thought of syndrome differentiation and treatment,the techniques of acupuncture and moxibustion,and the theory of warm diseases of TCM have been inherited and developed in Vietnam,forming diagnostic and treatment methods and the thought of medication adapted to such factors as Vietnam's climate. Under the influence of the Ming and Qing governments,Vietnam's medical and health system was continuously improved,and TCM became an important part of Vietnam's medical education. TCM classics have exerted a profound influence on Vietnam's traditional medical thoughts and the way of recording medicines. This not only promoted the cultural exchange of TCM and improved Vietnam's medical theoretical system,but also provided references for the multimodal international dissemination of TCM in today's top-level design,communication paths,cultural identity and international education models.
