Robben, who won a match-winning injury-time penalty to secure a 2-1 win for the Netherlands, admitted later he had dived in a failed attempt to win a spot-kick earlier in the match.
However, FIFA spokeswoman Delia Fischer ruled out any possibility of retrospective actions when asked about Robben's comments at a briefing today.
Fischer said sanctioning after the fact only applied to "serious infringements of foul play which have escaped the notice of the match officials."
"Media have interpreted statements from Robben in a Dutch post match interview completely wrong," the KNVB said.
