Outgoing CPI head Billy Liu, who is moving to a new role at Chevron’s Houston headquarters, expressed confidence in his successor: “Khun Bon has demonstrated strong leadership by driving growth while putting people and partners at the center. I am confident CPI will continue to thrive under his direction.”
