No ranking points will be awarded at Wimbledon this year due to the ban on Russian and Belarusian players, the ATP confirmed on Friday.
The All England Club announced the blanket ban last April following Russia's invasion of Ukraine. In its statement, it said the championships had a responsibility to help "limit Russia's global influence through the strongest means possible".
Russian and Belarusian players have been allowed to continue playing under a neutral flag, with the Tour saying Wimbledon's decision not to accept their entries was "unfair" and had "the potential to set a damaging precedent for the game".
The governing body for men's tennis has now decided that no ranking points will be on offer at SW19 unless the All England Club lifts the ban. There was no concurrent announcement from the WTA.
A statement from the Tour read: "The ability for players of any nationality to enter tournaments based on merit, and without discrimination, is fundamental to our Tour.
"The decision by Wimbledon to ban Russian and Belarusian players from competing in the UK this summer undermines this principle and the integrity of the ATP ranking system. It is also inconsistent with our rankings agreement.
"Absent a change in circumstances, it is with great regret and reluctance that we see no option but to remove ATP ranking points from Wimbledon for 2022.
"Our rules and agreements exist in order to protect the rights of players as a whole. Unilateral decisions of this nature, if unaddressed, set a damaging precedent for the rest of the Tour. Discrimination by individual tournaments is simply not viable on a Tour that operates in more than 30 countries.
"We greatly value our long-standing relationships with Wimbledon and the LTA [Lawn Tennis Association] and do not underestimate the difficult decisions faced in responding to recent UK government guidance.
"However, we note that this was informal guidance, not a mandate, which offered an alternative option that would have left the decision in the hands of individual players competing as neutral athletes through a signed declaration. Our internal discussions with affected players in fact led us to conclude this would have been a more agreeable option for the Tour.
"We remain hopeful of further discussions with Wimbledon leading to an acceptable outcome for all concerned. More broadly, we believe this matter again highlights the need for a united governance structure across professional tennis so that decisions of this nature can be made in a joint manner."
The statement added: "Our condemnation of Russia's devastating invasion of Ukraine remains unequivocal. Immediate action was taken to suspend the ATP Tour event in Moscow and have Russian and Belarusian athletes compete under neutral flags on Tour.
"In parallel, we have continued our humanitarian support for Ukraine, together with the other governing bodies of tennis, as well as providing direct financial assistance to many affected players."
