Premier Wu Den-yih (吳敦義) yesterday said operations at two Formosa Plastics Group petrochemical plants in Yunlin County’s Mailiao Township (麥寮) would remain suspended until the cause of the fire on Sunday has been identified and rectified.

Wu made the remarks after meeting Yunlin County Commissioner Su Chih-feng (蘇治芬), Formosa Group representatives and residents, as part of a trip to the county yesterday — his first visit to the area since a fire broke out at the No. 6 naphtha cracker complex.
