Ma Qing Hua and Norbert Michelisz were handed post-race penalties in the second World Touring Car Cup (WTCR) race at Ningbo, with Ma penalised for hitting Yann Ehrlacher whilst Michelisz was punished for not respecting track limits.
Boutsen Ginion Racing's Ma made contact with fellow Honda driver Ehrlacher on the last lap of the race, eliminating the Münnich Motorsport driver from what was tenth position.
The Chinese driver was handed a post-race drive through penalty, adding 30 seconds to his finishing time and dropping him from 14th position to 17th in the revised result.
BRC Racing's Michelisz, meanwhile, was hit with a smaller five-second time penalty for not respecting track limits, dropping the Hyundai racer from ninth to 11th and losing him the two points he would have added to his tally.
That means Michelisz loses a small amount of ground in the title race, leaving him 46 points adrift of team-mate Gabriele Tarquini.
Comtoyou Racing's Frédéric Vervisch had initially been given a post-race 10-second penalty for contact with Ehrlacher which had initially dropped the Frenchman out of a podium position, but the penalty was revoked when "new significant and relevant elements not previously available" were considered, along with additional video evidence.
