The Chinese Football Association has implemented a restriction on Chinese Super League clubs buying foreign players, making it so clubs in debt must match the transfer fee of a foreign player with a donation to a development fund.
Per ESPN FC's Michael Church, the CFA released a statement explaining the decision: "To benefit the healthy and steady development of professional football leagues and curb the irrational spending on players, those clubs which are in the red should pay the same sums of money as they are spending on buying players to the Chinese Football Development Fund.
