Did you know2019
Hengyi Petrochemical is tracked as a Chinese polyester producer, but its Brunei refinery (PMB) makes it simultaneously an energy supplier to Southeast Asia. PMB refines crude oil for Brunei's domestic fuel market and for regional export, while also producing paraxylene for the polyester supply chain. A Chinese polyester company owns significant Southeast Asian refining capacity — meaning Hengyi straddles both the Chinese textile supply chain and regional energy supply infrastructure in a ASEAN country with disputed South China Sea adjacency. The polyester fiber supply chain and regional energy security are co-located in the same Chinese-invested Bruneian industrial zone.
Brunei Direct ↗Origin2023
Hengyi Group was founded in 1993 in Hangzhou by Qiu Jianlin, initially in textiles before integrating into polyester chemistry. The Brunei investment (the PMB complex on Pulau Muara Besar island, commissioned 2019) was a strategically unusual move: a Chinese private-sector polyester company building a major crude oil refinery in a ASEAN sultanate. The Brunei refinery was facilitated by Chinese Belt and Road Initiative frameworks and Brunei's desire for industrial development, giving Hengyi direct crude access outside China while positioning the company to supply Southeast Asian markets with paraxylene and refined fuels.
