Do not start with “which is better”. Run through a three-layer filter in this exact order — 80% of cases get an answer at layer 1 or 2: (1) does the law mandate a joint venture; (2) if not, do you need absolute control; (3) if not, what is a local partner actually worth versus its price.
Layer 1 — Legal compulsion: check market access conditions
Under Investment Law No. 143/2025/QH15 (effective 1 March 2026, replacing Law 61/2020/QH14), certain sectors apply market access conditions to foreign investors: some mandate a joint venture, others cap foreign ownership ratios. The restricted-sector list is published with the law’s implementing documents — and is being updated under the new law.
This is a hard filter: if your sector is on the restricted list, the 100% foreign-owned route is infeasible from the outset, and every subsequent calculation must be built on a joint-venture foundation. Do not design your ownership structure before checking the list in force when the project is structured.
Layer 2 — Control needs: is technology your existential asset?
If the law does not compel a structure, the next question is control. A 100% foreign-owned company gives absolute decision-making power: strategy, senior hires, pricing — and above all, protection of core technology, production processes and trade secrets without sharing them with anyone.
A joint venture means sharing control according to capital ratios and the charter agreement. Many investors underestimate this: material decisions — capital increases, stake transfers, dissolution, approval of large transactions — typically require consensus. If technology is your core asset, think very carefully before bringing a partner into the ownership structure.
Layer 3 — Local partner value: what is it worth?
If the first two layers give no clear answer, price what a domestic partner brings: land and industrial-park premises, sectoral sub-licenses, an existing distribution network, and working relationships with local authorities. For a first-time investor in Vietnam, a good partner can shave months off procedures.
But diligence the partner like a mini-M&A deal: financial capacity, reputation, dispute history. And if you choose a joint venture, the JV contract/charter must spell out from day one a deadlock resolution mechanism, pre-emption rights on capital contributions, and exit provisions. Most JV disputes we handle trace back to parties leaving these clauses “for later”.
The timing trap: lock the model before filing the IRC
A common and costly mistake is filing for the Investment Registration Certificate (IRC) under one model and changing course midway. Switching from a joint venture to 100% foreign ownership (or vice versa) is not a simple amendment — it is an investment project adjustment: re-assessing market access conditions, amending the charter, and in many cases re-doing capital-contribution registration. The licensing authority treats this as a material project change. The cheapest moment to get the structure right is before the first dossier is filed.
Five-step checklist before deciding
- Check the current restricted-sector list for foreign investors — is 100% ownership even feasible?
- List assets requiring absolute protection (technology, brand, data) and your tolerance for shared control.
- Price the real need for a local partner: land, sub-licenses, distribution — could these be bought as services instead of shared ownership?
- Diligence the JV partner like a mini-M&A transaction.
- Draft deadlock mechanics, pre-emption rights and exit clauses before contributing capital.
FAQs
My sector has market access conditions but I still want absolute control — any way?
In some sectors the law allows foreign investors to hold a controlling (e.g. above 50%) though not 100% stake — effective control can be secured through the charter (veto rights, board seats, CEO appointment rights) rather than outright ownership. But this line is fragile: any structure designed to circumvent market access conditions risks being treated as a violation. Each sector needs counsel review.
Is a 51/49 joint venture enough for me to stay in control?
Not automatically. 51% gives you an ordinary majority, but charter-reserved matters typically require a higher threshold (e.g. 65–75%) or unanimous consent. Real control lives in the charter and the JV contract, not in the number 51.
Can I start as a joint venture and buy it out to 100% later?
Yes — provided the sector is no longer restricted at the buyout time and the JV contract contains clear exit/pre-emption clauses. This is a common roadmap: use the local partner for market entry, buy out once established. The precondition is that exit terms are written on day one — negotiating a buyout after a fallout is always far more expensive.
How hard is it to switch from 100% to a joint venture midway?
Procedurally it is an investment project adjustment (amending the IRC) plus a partial stake transfer, charter amendment and enterprise registration (ERC) update. Substantively you are “selling” part of the company — valuation, diligence on the new partner, and a negotiated JV contract are required. It is not a one-stop procedure.
