Hamilton had accused Rosberg of deliberately crashing into him in order to "prove a point".
Rosberg, meanwhile, denied this.
"I've been told what Lewis said in the press and the way he has stated his version of the events. All I can say is that my view of the events are very different," he said.
"The thing is it's just better that I don't now give all the details of my opinion and things like that. I hope you respect that. I prefer to just keep it internal."
He was supported by Mercedes team chief Toto Wolff.
"Nico felt he needed to hold his line. He needed to make a point. He (Rosberg) didn't give in," he said. "He thought it was for Lewis to leave him space, and that Lewis didn't leave him space. So they agreed to disagree in a very heated discussion amongst ourselves, but it wasn't deliberately crashing. That is nonsense."
Now the FIA have confirmed they will not be intervening in the matter, sticking to the stewards' initial decision that the collision was a racing incident.
"The FIA will not intervene in this issue," a spokesman said. "Only a 'new element' that would have appeared after the results became final could justify us opening an investigation. A comment alleged to have been made in an internal briefing and later denied by the team itself does not constitute such a 'new element'."
