European nations will boycott all FIFA competitions until the global body drops its controversial plan to sell stakes in a World Cup company.
On Friday, CONCACAF, the regional body for North and Central America and the Caribbean, rejected the plans, although stopped short of threatening a boycott.
The Asian Football Confederation (AFC), which counts Australia among its members, joined the condemnation in a hammer blow to Infantino's grand plans - and potentially his FIFA presidency.
"The AFC stands in solidarity with UEFA and CONCACAF in expressing serious concerns over FIFA's proposal to introduce private investment into FIFA's flagship competitions and the decision-making process around FFE," it read.
"The fact that the situation has reached the point where the real possibility of a FIFA World Cup boycott has entered public discourse should concern everyone who cares about the future of our game. Football should never have been placed in such a position."
The AFC said the debate had exposed "fundamental weaknesses in FIFA's consultation and decision-making processes" that needed addressing.
"The AFC calls upon FIFA to undertake an urgent review of its governance and decision-making framework to ensure that proposals of global significance are developed through proper consultation, meaningful engagement and appropriate oversight by FIFA's statutory bodies," it said.
FIFA earlier said it was not "selling football" and broadcast its intent to push ahead with consultations on the plan, which requires approval from a majority of FIFA's 211 member associations.
But collective opposition from AFC's 47 members, added to CONCACAF's 41 and UEFA's 55, would mean 143 now stand against it.
UEFA member associations had gathered virtually for a crisis meeting and afterwards issued a statement that puts them on a direct collision course with the world's governing body.
"No UEFA national teams will participate in any FIFA competition for so long as these proposals remain alive, unless this proposal has been abandoned in its entirety and binding assurances have been given that FIFA will never again open its governance or competitions to private ownership," it read.
FIFA issued details of their plans to create FIFA Forward Enterprise (FFE) after media reports were published on Tuesday afternoon.
FFE would be owned and controlled by FIFA but the intention is to sell minority stakes to private investors.
The lead investor is proposed to be Thrive Eternal, a company founded by Joshua Kushner, the brother of United States President Donald Trump's son-in-law, Jared Kushner.
"UEFA and its 55 member associations stand as one," European football's governing body said in their statement.
"We unanimously and unequivocally reject FIFA's proposal to transfer ownership interests in the World Cup and other FIFA competitions to private investors.
"The World Cup cannot be treated as an investment product. It is one of football's greatest sporting legacies. No part of it should ever be surrendered to private investors. The World Cup is not for sale."
CONCACAF said their membership expressed "deep concerns about the lack of due process surrounding the proposal, a short deadline and the absence of any review or approval by relevant FIFA governance bodies."
FIFA said the plans would enable them to make significant increases to the development funding available to national associations – up to $A14.2 billion ($US10 bn) – in the three-year cycle between 2027-2030.
Associations were asked to make a decision by September 19 on whether they supported the idea of private investment.
