Wimbledon is set to donate more than £500,000 to Ukraine relief after the "difficult decision" to lift its ban on Russian and Belarusian players.
The All England Club (AELTC) and Lawn Tennis Association (LTA) will also fund accommodation for Ukrainian players.
Russians and Belarusians were not allowed to play last year in response to Russia's invasion of Ukraine.
Chairman Ian Hewitt said lifting the ban did not lessen the AELTC's "total condemnation" of the invasion.
Wimbledon and British tennis' governing body the LTA were punished for their stance last year by the WTA and ATP with heavy fines and the removal of ranking points, and overturned the ban last month.
