The championship is contested by a combination of regulations with Group N competing directly against Super 2000 cars for points.
Indian driver Gaurav Gill won the Asian-Pacific championship after many years in the series.
Gill won the championship despite his Finnish team mate Esapekka Lappi winning more events.
Gill wrapped the title up early as the only rival outside of the Team MRF squad, Subaru driver Sanjay Takle, did not attend the final round at the China Rally.
The Asia Cup was won by New Zealand driver Michael Young.
