The state-owned oil and gas company said in a statement that the investigation was in relation to a contract awarded to a Malaysian subsidiary of an international upstream company in 2021.

“Petronas had given its full cooperation to the MACC in the investigation which has not found any wrongdoing by Petronas, its employees and directors,” it added.

The MACC had opened an investigation into allegations of graft involving a Petronas project and an international oil and gas company for the project in Sarawak.

The anti-graft agency was reported to have said that it had identified several procedural issues in relation to the project.

It proposed improvements to the project’s standard operating procedures as a preventive measure.

Petronas said it would continue to improve and strengthen its standard operating procedures to prevent and fight “all forms of corruption and misconduct”.
