Type
joint venture
Based in
China

Huajin Aramco Petrochemical Company (HAPCO) is building and will run an integrated refining and petrochemical complex in Panjin City, Liaoning Province, in northeast China. The complex combines a 300,000 barrel per day refinery with a petrochemical plant designed for annual capacity of 1.65 million metric tons of ethylene and 2 million metric tons of paraxylene, aimed at Chinese demand for transport fuels and chemical feedstocks. It brings together three partners: the Chinese defence and industrial conglomerate NORINCO Group through its North Huajin refining business, Panjin Xincheng Industrial Group, which anchors the project in the local Panjin petrochemical base, and Saudi Aramco, which contributes capital and a long term supply of up to 210,000 barrels per day of crude oil as feedstock. Construction started in the second quarter of 2023 after the project cleared its administrative approvals, with the complex scheduled to be fully operational by 2026.

Source

Huajin Aramco Petrochemical Co., Ltd. (HAPCO) files nothing with the SEC, so none of this comes from a filer record. The description was written for this site in August 2026 from Aramco JV HAPCO to commence construction of major refinery and petrochemical complex in China (Aramco press release via PR Newswire), Aramco JV HAPCO to commence construction of refinery and petrochemical complex (Hydrocarbon Engineering) and Aramco grows downstream presence in China (Oil & Gas Journal). The ownership figures below come from the holders' filings instead, and are sourced row by row.

Where each figure comes from

A private stake has no ownership form behind it, so the source is always the holder's own filing or disclosure. Anything modelled says so, with the arithmetic.

What this page is not

It is not a complete register. It lists the holders who happen to be inside the researched set and disclosed the stake themselves. A private company can have many other shareholders, and nothing here rules them out: venture investors, founders and employees usually appear in no public filing at all. Percentages are of Huajin Aramco Petrochemical Co., Ltd. (HAPCO) where a holder stated one, and are missing where no holder did.
