| Medical assistance is an important part of China's foreign aid. At present, the literature about teaching and training of foreign medical assistance is not frequent to find. Cambodia is a friendly diplomatic country of China, and the Changzheng Hospital has undertaken medical assistance about 13 years. This paper summarized the medical training and teaching experience of Changzheng Hospital to Preah Ket Mealea Hospital of Cambodia, including Department of Anesthesiology, Neurosurgery, Cardiovascular Center, Radiology and so on in recent years, and found that teaching methods combining various teaching approaches, cooperating with multiple departments, teaching students in accordance with their aptitude, and having flexible time and space are more suitable for Cambodia. The experience of assisting Cambodia can be further used in other countries, and establish an improved teaching system which is suitable for their national conditions and educational systems according to different medical status of different countries.
