During the event, new laws were passed which will see an automatic 10-game ban handed to players found guilty of racist abuse.
Racism has been an unfortunate feature of the game in recent years, with Premier League stars Luis Suarez and John Terry among the most high-profile players to receive bans for racial abuse.
Serie A has also been beset by issues. Milan midfielder Kevin Prince Boateng refused to continue playing a mid-season friendly against Pro Patria after being abused, while Lazio, Roma and Inter have also made headlines after being handed fines for derogatory chanting from their fans.
The congress also saw a woman appointed to the FIFA executive committee for the first time, as Burundian Football Federation chief Lydia Nsekera was inducted into the law-making group. 
"The results of the congress are very promising," Blatter said. 
"Promising for the future of FIFA because we have taken decisions which are really historical decisions. I just want to mention the resolution against discrimination and racism.
"The second one is that finally, after 109 years, we have one lady normally elected by the Congress and not by a federation, for four years, full member in the FIFA Executive Committee. 
"I welcome Lydia Nsekera, she is the president of the Burundi Football, but she is also a member of the IOC (International Olympic Committee), and therefore my colleague in the IOC."
