Chinese Super League clubs will have to pay a 100% tax on foreign signings as their mid-season transfer window opens on Monday.
The country’s Football Association (CFA) is proposing the new rule in order to try to curb the league’s extravagant spending.
Any club that pays a transfer fee above €5.9 million (£5.1m) for a foreign player has to pay the equivalent amount to the Chinese Football Development Foundation, which would in effect double the fee for any player.
Chelsea’s Diego Costa and Borussia Dortmund’s Pierre-Emerick Aubameyang have both been heavily linked to Chinese Super League clubs, as has Wayne Rooney.
However with the new spending rule, it is unlikely that these players will be moving there this summer.
