A new immigration regime took shape in China when the reform and opening up started in 1978. The host country of new Chinese immigrants are mostly western countries, and this is a distinction between the old and the new Chinese immigrants. Among all the new Chinese immigrants, the rate of European Chinese in recent 30 years is the most fast-growing comparing to other regions. This analysis is about the cause of the population fast growing which is inconsistent with the purpose of the closed migration policy in many European countries. The author used Massey et al\'s international migration theory and classified the dynamics into 3 dimensions - actor-network, structure and cumulative causation.
