Occidental Chemical Shuns Vietnam Venture: The unit of Los Angeles-based Occidental Petroleum Corp. has pulled out of a $109-million polyvinyl chloride resin venture in southern Vietnam, the Vietnam Investment Review said. The state-controlled weekly said Occidental Chemical Corp. walked away from the venture with Marubeni Corp. and two local firms because the authorities had licensed a rival project. The venture, Oxy-Vina Plastics & Chemical Co., was to be 40% owned by Occidental Chemical; 30% by Marubeni; and 15% by each of the two Vietnamese firms, Vietnam Gas Co. and Import-Export-Technical Raw Material Trading & Supply Co.
