In 1975, the Taiwan government invited FEG and U.S. company Union Carbide to establish Oriental Union Chemical Corporation (OUCC). In 1982, the Government moved in favor of trade liberalization, and allowed ethylene glycol (EG) to be imported to Taiwan. Union Carbide withdrew its investment in OUCC after evaluations. Despite all these obstacles during the period, OUCC did not fall, but weathered the storm and grew. It is now the major petrochemical force within FEG.
