Raikkonen was in fifth position when the Mexican tried to pass him on the entry to the chicane and the pair made contact, resulting in a left-rear puncture for the Lotus and dropping him down the field.
Perez, who later retired, claimed after the race that the Finn should have left him more room, but Raikkonen left no doubt as to where he felt the blame lie.
"He hit me from behind and that's about all there is to it," said Raikkonen, who recovered from the incident to claim a solitary point, having passed Nico Hulkenburg's Sauber for 10th on the final lap.
"If he thinks it's my fault that he came into the corner too fast then he obviously has no idea what he's talking about.
"It's not the first time he's hit someone in the race. He seems to expect people to be always looking at what he might do, then move over or go straight on if he comes into the corner too quick and isn't going to make it without running into someone."
With championship rival Sebastian Vettel finishing second to Nico Rosberg's Mercedes, Raikkonen concedes he has lost valuable ground to the German in the title fight - although 10th did extend his run of consecutive points finishes to 23.
"It was a really disappointing day," Raikkonen said. "Because of one stupid move from Sergio we've lost a lot of points to Sebastian in the championship and you can't afford to lose ground like that.
"Not the ideal weekend but there's nothing we can do about it. At least we got one point back at the end."
