Belarusian Prosecutor-General Pyotr Miklashevich said Alyaksandr Barouski, who headed the Belarusian State Petrochemical Industry Concern (Belnaftakhim) had been charged with embezzlement, abuse of office, and disclosing state secrets.
Miklashevich told a press conference in Minsk that the charges were related to crude and petroleum deliveries.
Barouski was arrested last month along with several other heads of state-run and private companies.
Belnaftakhim accounts for more than one-fourth of Belarus's exports.
In connection with the same case, Miklashevich said two officers in Belarus's KGB and one police officer have been arrested and charged with taking bribes.
