Ngomhla ziyi-14 kuNhlaba, izifundo ezimbili, “Ukuqhathaniswa Kokwakhiwa Kwekhoyili Engangeni Manzi” kanye “Nokuthuthukiswa Okujwayelekile Kwamaqembu Etiyela Angangeni Manzi”, zenziwa ngokugcwele embonini yokuqala yokuhlola i-asphalt engangeni manzi yasePetroChina.Lezi yizifundo ezimbili zokuqala ezethulwe ngemuva kokwembulwa kwesisekelo ngo-Ephreli 29.

Njengesisekelo sokuqala sokuhlola umshayeli waseChina Petroleum setiyela elingangeni manzi, isikhungo socwaningo senkampani kawoyela kawoyela kanye neJianguo Weiye Group namanye amayunithi azozibophezela ekukhuthazeni nasekusetshenzisweni kwemikhiqizo emisha yetiyela engangeni manzi, ukuthuthukiswa ngokubambisana kwetiyela elingangeni manzi kanye nemikhiqizo ehlobene nayo, kanye nokuthuthukiswa kobuchwepheshe kulesi sisekelo sokuqeqeshwa kwe-Exchange, ukwenza umsebenzi wocwaningo mayelana nokusetshenziswa kwezimboni kwemikhiqizo yetiyela engangeni manzi.Izoba isizinda sokufukamela sokuguqulwa kwemikhiqizo emisha kanye nobuchwepheshe obusha bePetroChina, okubaluleke kakhulu ukusheshisa ukukhuthazwa nokusebenzisa imikhiqizo yetiyela engangeni manzi yePetroChina kanye nokuhlinzeka ngemikhiqizo yetiyela engangeni manzi engcono neyongayo embonini engenamanzi.

Njengomkhiqizo osezingeni eliphezulu emndenini we-asphalt, i-asphalt engenamanzi ibe yizinhlobonhlobo ezinkulu ze-asphalt ngaphandle kwe-asphalt yomgwaqo.Ngonyaka odlule, ukuthengiswa kwe-asphalt ye-petroleum engangeni manzi yaseChina kwafinyelela amathani ayizigidi ezingu-1.53, nesabelo semakethe esingaphezu kwama-21%.
