Considering the close genetic connection between South and North China, the Tibetan Plateau and the northward subduction zones of the Australian and Indian Ocean plates, all are included in the Southeast Asian tectonic region. The larger Southeast Asian tectonic domain is divided into the Tethys, mountain and arc, extrusion escape, Sundaland, eastern marginal sea, and the Philippine Arc tectonic domains. Overall, research in Southeast Asia is insufficient due to geographical and historical issues, and there are still many unsolved geoscience-related issues. Among them, the splitting and collage of the Tethys block from Gondwanaland, the existence and extinction of the proto-South China Sea, the formation mechanism of the present South China Sea, the attributes of the Philippine Arc active zone and the New Guinea Arc, and the relationship with the proto-South China Sea, are scientific issues worthy of attention in future geoscience research in Southeast Asia.
