As the core of the overseas Chinese society, the Chinese and overseas Chinese community is also a significant force in spreading Chinese culture overseas. In recent years, more and more newly-emerged "new migrants" associations have gradually shaped into fresh blood in the promotion of Chinese culture overseas, showing a great many new characteristics in the practice of promoting Chinese culture. Unfortunately, very limited related researches exist. This article hereof has summarized five new characteristics of the Chinese and overseas Chinese "new migrants" association in Thailand when promoting Chinese culture, namely younger members, diversified promotion fields, modernized promotion means, epochal promotion contents and close contact with the motherland. In consideration of different priorities manifested in the traditional community and the "new migrants" one respectively, the author strongly believes that better effects will be achieved and faster overseas spreading of Chinese culture can be reached if the best of the two communities above could be made.
