Pastor Maldonado, Williams, China 2012Pastor Maldonado and Pedro de la Rosa have been given reprimands for impeding other cars during qualifying for the Chinese Grand Prix.

Williams driver Maldonado was under investigation for having blocked Caterham's Heikki Kovalainen, who said after qualifying that he was expecting the Venezuelan to be penalized. Maldonado, however, was only reprimanded by the stewards.

"He was weaving on the back straight and I was getting very close to him, so obviously he had no intention of letting me by. By the last corner I was right up his bum," said Kovalainen. "It didn't cost us much time because I was able to do another lap later on, but in any case he made a mistake and I think he'll probably have to pay for it."

De la Rosa was reprimanded for having impeded Maldonado's teammate Bruno Senna during Q1.
