The announcement late yesterday comes after similar decisions this month by South Africa and Burundi to abandon the troubled institution, set up to try the world's worst crimes.
Information Minister Sheriff Bojang said in an announcement on state television that the court had been used "for the persecution of Africans and especially their leaders" while ignoring crimes committed by the West.
He singled out the case of former British prime minister Tony Blair, who the ICC decided not to indict over the Iraq war.
The withdrawal, he said, "is warranted by the fact that the ICC, despite being called International Criminal Court, is in fact an International Caucasian Court for the persecution and humiliation of people of colour, especially Africans".

The ICC, set up in 2002, is often accused of bias against Africa and has also struggled with a lack of cooperation, including from the United States, which has signed the court's treaty but never ratified it.
The decision will also come as a personal blow to the court's chief prosecutor, Fatou Bensouda, a former Gambian justice minister.
The court at the weekend asked South Africa and Burundi to reconsider their decisions to leave, which came as a major blow to the institution.
"I urge them to work together with other States in the fight against impunity, which often causes massive violations of human rights," Sidiki Kaba, president of the assembly of state parties to the ICC founding treaty, said in a statement.
