US prosecutors have opened a case against Chadian diplomat Mahamoud Adam Bechir, his former deputy and his wife for allegedly taking a bribe from a Canadian oil company.
The three had promised the company oil deals from their country and were given $2m ($1.4m), according to the US Justice Department.
Mr Bechir was at the time the ambassador to the US.
He is now Chad’s ambassador to Russia and presented his credentials to the Russian president on 18 May, according to photos from the Russian News Agency Tass.
The three have not commented.
The founding shareholder of the Canadian firm, Naeem Tyab, was arrested in 2019 and pleaded guilty to bribery charges, the justice department said.
The three Chadians are yet to be arrested.
