Zabeel Investments have pulled out of a deal to buy Charlton, the Championship club confirmed today.
The Dubai-based investors, who had also been linked with a takeover of Newcastle, made an indicative offer for the club earlier this month.
A Charlton statement said: "Zabeel Investments has informed Charlton that the decision not to proceed was taken on the basis that its focus moving forward will be on domestic opportunities in Dubai that complement the current Zabeel Investments portfolio.
"This combined with the current debate around foreign ownership of football clubs and the worsening economic climate in the UK contributed to the decision of Zabeel Investments to pull out.''
The news will come as a blow to the Addicks, who have reported debts of £20million and were ready to sell.
The club are in the final year of their parachute payments having been relegated from the Premier League in 2007 and dropped to 20th in the table following Tuesday night's home defeat by Bristol City.
Zabeel were this week reported to have turned their attentions to Everton, although they insist they are no longer in the market for an English club.
The statement continued: "Zabeel Investments has made it clear to Charlton that this decision was not made as a result of any discoveries during the due diligence process.
"Contrary to recent press reports, Zabeel Investments has confirmed to Charlton that it has not approached any other club since it made an indicative offer for Charlton Athletic on October 10, nor has it authorised any approach on its behalf.
"In addition, Zabeel Investments has confirmed it has no current intention to acquire any English football club for the foreseeable future.''
A spokesman for Zabeel Investments added: "Zabeel Investments has the highest regard for both the supporters of Charlton and the way in which Charlton is managed and wishes the team every success in their quest for promotion this season and moving forward.''
