Sam Bankman-Fried was charged with bribing Chinese officials, adding a new dimension to the U.S. government’s case against the FTX co-founder.

The new charge was unsealed Tuesday in a revised indictment by federal prosecutors in Manhattan. Bankman-Fried is accused of authorizing the payment of $40 million to get Chinese officials to unfreeze accounts at Alameda Research, a Hong Kong-based trading firm affiliated with FTX, holding more than $1 billion.

According to prosecutors, the Alameda accounts were frozen in 2021 as part of a Chinese government investigation into two cryptocurrency exchanges in that country. Those exchanges were OKX and Huobi Capital, according to people familiar with the matter.
