While it welcomes Leonardo DiCaprio's undertaking to return funds or gifts given to him and the Leonardo DiCaprio Foundation (LDF) that is linked to embezzled 1MDB funds, the Centre to Combat Corruption and Cronyism (C4) wants the actor to do more.

"The standard of accountability is high on DiCaprio. He is a renowned Hollywood actor and the UN Ambassador for climate change and a prominent public figure," read the statement from C4 executive director Cynthia Gabriel and Stanley Sudhagaran.

C4 said that it is imperative for the actor to now disclose all his financial links and dealings with controversial financier Jho Low, Prime Minister Najib Abdul Razak's filmmaker stepson Rizal Aziz, and the total money he has earned as gifts and payments from them during their friendship.
