FPG's naphtha cracker – the sixth petrochemical processing plant of that kind in Taiwan – was first proposed in 1973, but the ruling KMT government still imposed a monopoly at that time and denied permission. Permission was granted in 1986, as President Chiang Ching-kuo instituted reforms to loosen the authoritarianism instituted by his father, Chiang Kai-shek. At that time, FPG proposed a NT$90 billion complex that would be located in the Litzu Industrial Zone of Ilan County. Local residents opposed this plan on the basis of its environmental impact and, led by County Magistrate Chen Ding-Nan (陳定南), formed the Alliance against Sixth Naphtha Cracker. After a successful campaign, including a televised debate between Chen and FPG Chairman Wang, they eventually forced the company to look elsewhere. The second site proposed by FPG, in Taoyuan County's Kuanyin Industrial Zone, generated similar opposition from local residents.
