Asante Berko, a former managing director of the Tema Oil Refinery, is facing trial in the United States. The trial is taking place in Brooklyn.
Berko is accused of paying bribes amounting to $1 million. These payments were allegedly made to Ghanaian officials.
The purpose of the alleged bribes was to help a Turkish company secure a deal for a power plant project in Ghana.
Berko previously worked as a banker for Goldman Sachs before leading the Tema Oil Refinery.
Prosecutors claim the bribes were paid between 2015 and 2016. The trial is expected to hear evidence related to these transactions.
The case highlights international efforts to combat corruption involving officials and business dealings.
The US Department of Justice is prosecuting the case. Details of the trial proceedings are being closely watched.
