China's Football Association announced that any club that pays more than USD 6.63 million for a player transfer must pay the same amount to a CFA youth development fund.
The tax will be in place until the end of the Chinese league's summer transfer window on July 14. Transfers for Chinese players valued at over USD 3 million will also be taxed at 100 per cent.
Flush with cash from corporate backers, Chinese Super League clubs have shaken up international football in recent years by offering astronomical transfer fees and wages for players from European teams.
Over the past year, transfers like Shanghai SIPG's deals for the Brazilian duo Oscar and Hulk, who cost 60 million euros each, have brought a wave of attention to the Chinese league, but sports officials say the flashy purchases have done little to benefit Chinese football over the long term.
In recent weeks the CFA has also proposed a new rule that would require teams to play an under-23 Chinese player for every foreign player on the field.
After decades of dismal national team results, President Xi Jinping has pinpointed improving Chinese football as a top priority to boost national self-confidence and prestige.
