The petrochemical complex on Pulau Muara Besar island is a landmark project for Brunei's economic diversification. It is a joint venture between Brunei's Damai Holdings and China's Hengyi Group. The first phase, completed in 2019, centers on an integrated refinery capable of processing 8 million tonnes of crude oil annually. It produces a variety of petrochemical products, including paraxylene, benzene, gasoline, and diesel, primarily for export markets. The project has created thousands of jobs and significantly contributed to the nation's GDP growth. A planned second phase will further expand its capacity and product range, solidifying Brunei's position as a major player in the global petrochemical industry. The facility is connected to the mainland via the 2.7 km Pulau Muara Besar Bridge.
