Umzi-mveliso wePetrochemical luncedo olubalulekileyo kunye nomzi mveliso osisiseko we-china, ulungelelanise olona qoqosho, udlala indima yamashishini amabini, umthwalo omkhulu, kunye nokusetyenziswa kwendalo kubi kakhulu. Ngokusekwe kwiminyaka emininzi yamava eshishini, umbane we-SAIWEI unokubonelela abathengi ngezisombululo zokuhambisa amandla, kwaye banike isiqinisekiso esithembekileyo kumzi-mveliso we-petrochemical kunye nokukhula komgangatho, ukuze kufezekiswe ukusebenza kwenkqubo yokuhambisa amandla.
