Long Son Petrochemical Restarts Vietnam Operations after 10-Month Suspension

MANILA, PHILIPPINES--September 17, 2025--Researched by Industrial Info Resources (Sugar Land, Texas)--Long Son Petrochemical Co., Ltd (LSP), a subsidiary of Thailand's Siam Cement Group (SCG), invested more than $5 billion to build a petrochemical complex in Long Son Commune, Ho Chi Minh City (formerly Vung Tau City before the province was merged), Vietnam. The project includes an olefins plant with a 1.35 million ton-per-year (T/Yr) capacity and three polyolefin plants that can produce a combined 1.4 million T/Yr, along with essential port and storage facilities. In October 2024, just a month after the start of commercial operations, the plant was shut down due to volatile crude oil prices, which causes profits to fall.
