Clubs from Russia and Qatar are among six fined by FIFA and warned they risk one-year transfer bans for failing to settle debts to players.
FIFA said the clubs also face deductions of six league points if they fail to pay the debts in 30 to 90 days.
The clubs are: Kuban of Russia; Al Arabi and Al Kharaitiyat of Qatar; Zamalek of Egypt; Al Jazira of the United Arab Emirates; and Mersin Idman Yurdu of Turkey.
FIFA says all failed to comply with rulings by FIFA or the Court of Arbitration for Sport "to pay significant overdue amounts of money to players."
They were fined between $15,000 and $30,000.
FIFA also said national football federations face disciplinary cases if they fail to enforce the verdicts.
