In 2018 Erdogan signed a $100 million agreement to invest in oil exploration and production in Sudan.

Sudanese dictator Omar al-Bashir was overthrown April 11 2019 by military coup. He was a good friend and close ally of  Erdogan. During his 30-year rule, Bashir was indicted by the International Criminal Court in 2009 and 2010, charged with five counts of crimes against humanity, two counts of war crimes and three counts of genocide for his alleged mass killings in Darfur that cost some 300,000 lives.

Bashir could travel safely to only a few places in the world and Turkey was one of them. The last time he visited Turkey was right after the June 2018 elections to join Erdogan’s inauguration ceremony.

Erdogan signed a deal with Bashir to rebuild and expand docking facilities at Suakin's modern port, and to establish a military presence further up the coast in Port Sudan, access to Sudan's coastline has once again become the subject of international competition.

Turkish military and police established several bases in Sudan to train Bashir’s forces.

Sudan has an interim government. There are reports that Erdogan is working with Qatar and Islamist factions to regain his influence in Sudan.
