Leonardo DiCaprio has promised to return any gifts or donations to his environmental foundation or his movie The Wolf of Wall Street that were connected to a Malaysian wealth fund.
The Oscar winning actor says he is still awaiting direction from the US Justice Department pending a fraud investigation.
Court papers allege a complex money laundering scheme was intended to enrich top-level officials of the Malaysian government-controlled wealth fund.
A spokesperson for Leo said: "Both Mr DiCaprio and (the Leonardo DiCaprio Foundation) continue to be entirely supportive of all efforts to assure that justice is done in this matter.
"Mr DiCaprio is grateful for the lead and instruction of the government on how to accomplish this."
The Justice Department says that at least $3.5 billion has been stolen from the wealth fund, known as 1MDB, by people close to Malaysian Prime Minister Najib Razak.
Najib created the fund in 2009 shortly after he took office to promote economic development projects in the Asian nation, but the fund accumulated billions in debts over the years.
The Justice Department has initiated action to seize $1.3 billion it says was taken from the fund to buy assets in the US, including financing of The Wolf Of Wall Street, according to federal government complaints filed in Los Angeles in July.
