Question: The country's Football Association (CFA) is proposing the measure for loss-making clubs in order to try to curb the league's extravagant spending.
Chinese clubs spent £331m during the country's winter transfer window, which was more than their English Premier League counterparts in January.
The proceeds from the tax would go into a government-run fund.
If enforced, the measure would in effect double the fee for any player.
Manchester United striker Wayne Rooney and Chelsea striker Diego Costa are among the high-profile players to be linked with the Chinese Super League (CSL), with the transfer window open until 14 July.

In the last transfer window, Shanghai SIPG bought Brazil international Oscar for £60m from Chelsea, while Shanghai Shenhua spent £40m on Carlos Tevez. The Argentina striker signed a deal worth a reported £310,000 a week.
At the time, a spokesperson for China's General Administration of Sport said clubs in the country were "burning money".
Limits on the number foreign players in squads were put in place for the current season, which runs from March to November. Only three non-Chinese players can now be fielded in a fixture in a move the CFA hoped would tackle "irrational" spending.
Costa was a target for Tianjin Quanjian but the club's owner, Shu Yuhui, said in January that a bid to sign the forward had been scuppered by new CSL rules limiting the number of foreign players.
In each game next year, clubs will also have to field as many Chinese under-23 players as overseas players.
BBC Sport's Simon Stone:
The Chinese Super League transfer window has raised the potential for another massive deal being done for Wayne Rooney.
A move to China is one of a number of options for Rooney, which also include remaining at United for the final year of his contract.
However, he may wish to consider the fate of former team-mate Carlos Tevez, who joined Shanghai Shenhua on a mega deal earlier in the year.
Neither the team nor Tevez are performing to expectations and when the Argentina international was spotted at a theme park after missing a game through injury this weekend, fans went on social media to condemn him, with one saying he has "the worst attitude in the team's history".
Big money. Big demands.

Answer: Chinese Super League clubs face a 100% tax on signings as their mid-season transfer window opens on Monday.


Question: Detectives recovered new evidence from the strap of a bag found close to the bus stop where the 18-year-old A-level student was stabbed to death.
Improvements in forensic testing led to the breakthrough, the Met said.
Stephen Lawrence was murdered by a group of six white youths in an unprovoked attack in Eltham in 1993.
Gary Dobson and David Norris were found guilty of his murder and sentenced to minimum terms of 15 years and two months and 14 years and three months in January 2012.
The investigation into Mr Lawrence's death remains open, with around 13 officers still working on the case led by Det Ch Insp Chris Le Pere.
The black leather strap, which did not belong to Mr Lawrence, is believed to have been left in Dickson Road, by the junction with Well Hall Road close to the scene of the murder on 22 April.
The BBC understands there is no suggestion that a woman was at the scene of the attack but officers are seeking to establish who the bag belonged to, and why it was at the spot where Stephen was attacked.
A reconstruction and appeal for information will be shown on BBC's Crimewatch at 21:00 BST on Monday, on the eve of what would have been Stephen Lawrence's 42nd birthday.
His father, Neville Lawrence, will also appeal for further information about the murder.
Officers have spoken to around 110 people in connection with this line of inquiry, and gathered 50 DNA samples.
Police are still trying to trace a man reportedly seen in a distinctive green jacket with a V emblem near Well Hall Road Roundabout at about the time Mr Lawrence was attacked.
CCTV footage, recently digitally enhanced using techniques not available in 1993, showed him in a nearby off-licence hours before the murder took place.
In a sketch by a police artist, based on their accounts, the wearer of the jacket has light reddish hair.  However the man in the CCTV pictures is dark-haired.
Police say he could be a witness.

Answer: The DNA of an unknown woman has been found near to where Stephen Lawrence was murdered in south east London 23 years ago, Scotland Yard has said.
