City coach Patrick Vieira took his under-21 team off the pitch during the July friendly after claims French midfielder Seko Fofana, who had been shown a red card for an off-the-ball incident, had been racially abused just before half-time.
However, having investigated the matter, FIFA will not be taking any further action.
"The chairman of the FIFA disciplinary committee considered that, based on the information at his disposal, there were not enough elements to justify the opening of disciplinary proceedings," said a statement.
"Also in relation to this matter, the chairman was pleased to observe that Mr Davor Suker (Croatian Football Federation president) and Mr Patrick Vieira engage positively to work through the issue.
"The relevant parties were notified on Friday December 5 in the form of a letter, which also emphasised FIFA's zero-tolerance stance against any form of discrimination."
