Players or officials found guilty of racist offences in European club matches or internationals will face a minimum ban of 10 matches under tougher disciplinary regulations approved by UEFA's executive committee on Thursday.
The executive will also propose to their annual Congress in London on Friday that all their 53 national associations adopt the same sanction, although the English FA announced last week it would be imposing a minimum five-match ban for racist offences.
UEFA general secretary Gianni Infantino told a news conference following the executive meeting in central London that clubs would also face partial closure of stadiums for a first incident of racist abuse by fans and a full closure for a second offence plus a 50,000 euros fine.
There will also be an increased ban for players or officials insulting or assaulting match officials.
In the past, a two-match ban could be imposed for insulting the referee or officials but that has been increased to three matches, while the penalty for assault has been increased from 10 to 15 matches.
"We are sending a very strong message that this kind of behaviour will no longer be tolerated in any form," Infantino said.
The new sanctions, adopted by the executive committee, will initially apply to all matches in European competition, with UEFA hoping its members adopt the same punishments for their domestic matches.
That will be discussed at the Congress on Friday.
Infantino also announced new anti-doping initiatives including the launch of a research study retrospectively measuring the steroid profiles of nearly 900 players who have participated in UEFA competitions since 2008.
"UEFA wants to identify the potential relevance of steroid use across Europe by using data from previous doping controls. The study will be anonymous and there will be no penalties for any player incurring an anti-doping rule violation," he said
UEFA is also empowering itself to take action should one of its member nations fail to punish "or punish in an appropriate manner offences harming the essence of football - notably offences of match-fixing, corruption and doping", he added.
UEFA is also removing any period of limitation for offences of bribery and corruption.
"So, even if we find that a match was fixed 15 years ago, we will take action," Infantino said.
The new rules are planned to come into effect on June 1.
Racism has increasingly blighted the game in recent years, especially in eastern Europe. Last month FIFA president Sepp Blatter announced the world governing body was also setting up a new Task Force.
