Thanh Hoa’s FDI inflows have accelerated sharply, led by the Nghi Son Economic Zone, home to the Nghi Son Oil Refinery and a growing cluster of petrochemical, pharmaceutical and textile manufacturers. ECOVIS Vietnam Law helps international manufacturers set up and operate in Thanh Hoa — from investment licensing to land, construction and labour compliance.
Attorney Vu Manh Quynh is the Managing Partner of ECOVIS Vietnam Law, advising international investors on Foreign Direct Investment (FDI), corporate governance, and regulatory compliance in Vietnam.
Why manufacturers choose Thanh Hoa
Nghi Son’s refining and petrochemical base anchors the province’s industrial identity, while newer projects, including high-tech pharmaceutical and medical-device manufacturing and textile production, show Thanh Hoa diversifying beyond heavy industry into a broader manufacturing and supporting-industry base.
Thanh Hoa attracted US$120.6 million in new FDI in the first four months of 2026, roughly 4.8 times the same period in 2025, led by the Nghi Son Economic Zone (Thanh Hoa provincial reporting, 2026).
Practitioner insight — Vu Manh Quynh, Managing Partner: “Thanh Hoa is no longer a single-anchor economy built around the Nghi Son refinery. The pharmaceutical and medical-device projects moving in now face a different licensing path than the original petrochemical wave, and investors underestimate that difference.”

Frequently asked questions
Can a foreign investor build a wholly-owned factory in Thanh Hoa?
Yes. In most manufacturing sectors a foreign investor can hold 100% and lease land in an industrial zone, subject to project approval and the relevant licences.
What comes first — the IRC or the land lease?
Sequencing matters. We coordinate the IRC, the land / factory lease and construction approvals so commitments are made in the right order and on realistic timelines.
Do you handle labour compliance for factories?
Yes. We prepare labour contracts, internal labour regulations and social-insurance registration, and advise on work permits for foreign managers.
