Last update for 2016 champs by me the more the country is "exotic" the more info is scarce, so any correction is welcome:
China (only Chinese drivers eligible): Han Han - Subaru XV
Indonesia (as far as I understand, the rally championship was replaced by a rallysprint championship, at for 2016): Rizal Sungkar - Mitsubishi Lancer Evo X
Peru (ACP): Nicolas Traverso - Toyota Hilux (Mk8)
Thailand: Fan Fan (China) - Mitsubishi Lancer Evo X
