Players found guilty of racial abuse will face minimum suspensions of 10 matches, under plans laid out by UEFA general secretary Gianni Infantino on Wednesday.
Infantino also said racist offences would trigger partial stadium closures in the first instance and full stadium closures for a second incident.
The proposed punishments would affect all matches in European competition.
"We have to have sanctions and they must have a deterrent effect and what we are proposing is if a player or official is convicted of racism, they should receive a 10-match suspension at least," Infantino told the Soccerex forum in Manchester.
"If supporters at a club are found guilty of racist abuse, the first sanction will be a partial closure of the part of the stadium from which the racist abuse took place.
"For a second offence, there will be the full closure and a minimum fine of 50,000 euros ($65,000)."
