Sam Bankman-Fried, founder of failed crypto firm FTX, has been accused of bribing at least one Chinese official.
In new charges unveiled in the US, officials accused the entrepreneur of authorising a bribe of at least 40 million dollars to try to gain access to trading accounts frozen by Chinese authorities.
The allegations add to the fraud case filed last year after FTX's collapse.
Mr Bankman-Fried pleaded not guilty to those claims earlier this year.
He is currently under house arrest awaiting trial.
