By 2071, the Chinese had completed their purge of Islamic people from the territories they considered “critical” to the immediate interests of China.  The push advanced south through New Guinea and west through Nepal.  The western hegemony included Assam and other provinces of eastern India, the Chinese claim was that they required these provinces as a cultural buffer from future Islamic incursions. China invaded southeast Asia and the Indonesian archipelago to suppress the growing Islamic hegemony but also to bring the vital Bang Lang energy zone into their sphere of influence.
