"I have a good relationship with Lewis and I will not do anything to destroy it. Definitely not," Massa said.
"I'm not the kind of guy who brings problems on the track to the outside, and I will not change my approach."
Hamilton and Massa's hopes were both hit in the incident-packed race. The McLaren driver, his car damaged in the collision with Massa, failed to score points by finishing 12th, but Massa was only able to score two points for seventh place.
BMW Sauber's Robert Kubica has now joined them in the title fight - with a maximum of 20 points available, the Pole is 12 points behind Hamilton after finishing second behind Renault's Fernando Alonso at Fuji.
Hamilton can win the championship in China on Sunday if he scores six more points than Massa.
The incident between Hamilton and Massa happened on the second lap, when the Englishman was trying to make up ground he lost in an incident at the first corner, which dropped him to sixth.
We plan on winning; not at any cost, but we plan on winning

Hamilton dived down the inside into the first, right-handed part of the Turn 10/11 chicane and Massa ran wide. The Ferrari driver had his car fully over the kerbs as he went through the left-handed part and collided with Hamilton's McLaren as he rejoined the track.
"I went up the inside because Felipe braked late and gave me the advantage," Hamilton said.
The 23-year-old was was angry that he received the same penalty as Massa for a different incident at the first corner of the race.
Hamilton had made a slow start and was passed by Massa's team-mate Kimi Raikkonen on the run down to the first corner.
