Acquiring PPP / BOT Projects in Vietnam (2026): Regulatory Requirements, Assignment Consents and Practical M&A Checklist

Executive summary & quick takeaways (TL;DR)

PPP project acquisition Vietnam is a viable but procedurally demanding route for foreign buyers in 2026. The sector is governed primarily by the Law on Investment under the Method of Public-Private Partnership (the “PPP Law”) and its implementing decrees, alongside the general Law on Investment and the Law on Enterprises. An acquisition of a PPP or BOT project company is generally permitted, but it sits at the intersection of investment law, sectoral concession rules, land law and project finance, and each of those layers imposes its own consent requirements. Before committing capital, buyers should map the full approval chain and build regulatory conditionality into the transaction documents.

• Can foreign investors buy in? Yes, in most sectors, subject to foreign-ownership limits, sectoral restrictions and the consent of the contracting authority and relevant line ministry.
• Top consents to plan for. Contracting authority (or competent state authority) consent; competent line-ministry approval; investment-registration / M&A approval before the relevant investment-registration authority; lender consent; and land-authority sign-off where land-use rights change.
• Typical timeline. Straightforward assignments often run 60–180 days; complex deals involving foreign control, tariff re-approval or land conversion can exceed 360 days.
• Top deal protections. Conditional completion with escrow, robust seller warranties and indemnities, and pre-agreed lender and regulatory consent conditions precedent.

The recommended next step for any serious buyer is to engage Vietnamese counsel early and commission a regulatory pre-check before signing heads of terms. A short, well-targeted feasibility review of eligibility and consent routes will save far more than it costs by shaping the deal structure from the outset.

Can foreign investors acquire PPP/BOT projects in Vietnam? Required consents and eligibility

The threshold question for any PPP project acquisition Vietnam strategy is whether the foreign buyer is permitted to acquire the target at all, and on what terms. In principle, foreign investors can acquire shares in, or the assets of, a PPP or BOT project company, but the acquisition is governed both at the investor level and at the transaction level, and the two must be reconciled.

Legal basis under the Law on Investment and the PPP Law

The current framework for PPP projects derives from the Law on the Method of Public-Private Partnership Investment and its implementing decrees, while foreign capital contribution or share purchase is governed by the Law on Investment and the Law on Enterprises, as published through the National Assembly and the Vietnam Legal Documents Portal. Under this framework, a foreign investor acquiring an interest in an existing Vietnamese enterprise may need to register the capital contribution or share purchase with the competent investment-registration authority before completion, particularly where the target operates in a conditional sector or where the acquisition crosses foreign-ownership thresholds. For PPP and BOT companies, the investment-law approval sits alongside, not instead of, the sectoral concession consents.

Common sectoral exceptions and ownership ceilings

Infrastructure is not a single regulatory category. Transport concessions (highways, ports, airports) are supervised by the Ministry of Construction, which assumed the former Ministry of Transport’s functions following the 2025 government restructuring; energy, water, and other utilities fall under their own line ministries and sector rules. Several sectors impose foreign-ownership ceilings or require that a state-owned or domestic counterpart retain a controlling or blocking stake. A buyer evaluating an acquisition of infrastructure projects Vietnam should confirm early whether the specific sector permits majority foreign control, because that single fact can determine whether a share deal or an asset deal is even feasible.

Practical pressure points

Beyond the headline rules, several practical factors frequently stall transactions:

• State-owned counterpart approvals. Where the contracting authority or an equity partner is a state entity, internal approval processes can be slow and opaque.
• Change-of-control clauses. Most concession and project-finance documents contain change-of-control provisions that treat a share acquisition as a triggering event requiring prior consent.
• Conditional-sector registration. If the target carries business lines that are conditional for foreign investors, the registration step can add weeks and additional documentary demands.

For the broader investment-law context underpinning these points, see the M&A & Investment, Vietnam (practice note), which sets out how foreign-investment approvals interact with transaction-level filings.

Assignment consent process for BOT contracts: authorities, required documents and sample timeline

The assignment consent process is the core regulatory workstream in almost every PPP project acquisition Vietnam transaction. A BOT concession is a contract between the project company and a competent state authority; transferring control of that company, or assigning the contract itself, generally requires that authority’s consent. Getting the consent workflow right is the difference between a clean completion and a deal that drifts for a year.

Who grants consent

Responsibility for granting assignment consent depends on the level and sector of the project:

• Contracting authority. For locally procured projects this is typically the provincial People’s Committee; for nationally significant projects it may be a central authority.
• Competent line ministry. For transport BOTs, the Ministry of Construction is the key sectoral approver of the assignment and any related tariff or scope changes.
• Investment-registration authority. Where the buyer is a foreign investor, the competent investment-registration authority (typically the provincial Department of Finance, which absorbed the former Department of Planning and Investment) handles the foreign-investment approval dimension of the transaction.
• Land authority. The Ministry of Agriculture and Environment (which assumed the former Ministry of Natural Resources and Environment’s land functions) and its provincial departments become relevant where land-use rights are affected by the transfer.

Because a single bot project transfer Vietnam deal may need all of these approvals in sequence or in parallel, deal teams should prepare a consolidated approvals map that identifies each decision-maker, the legal basis for their consent, and the documents each requires.

Documents required for assignment consent

While the exact document set varies by ministry and sector, a typical assignment consent BOT Vietnam application package includes:

• A formal assignment or change-of-control application letter addressed to the contracting authority.
• The original concession/BOT contract and any amendments or side letters.
• Corporate approvals of both seller and buyer (board and shareholder resolutions authorising the transaction).
• Audited financial statements and evidence of the buyer’s financial and technical capacity to perform the concession.
• The draft share purchase or asset transfer agreement, or a term sheet, showing the proposed structure.
• The buyer’s corporate and ownership documents, including ultimate beneficial ownership disclosures.
• Where relevant, lender consent or a lender no-objection letter.

Authorities will scrutinise the buyer’s ability to step into the project’s obligations. Demonstrating operational competence, not just funding, is often decisive, particularly for transport and utility concessions where service continuity is a public-interest concern.

Timing and statutory review periods

Statutory review periods differ across ministries and sectors. As a planning benchmark, straightforward transport BOT assignments commonly fall within a 60–180 day window once a complete application is filed, while deals that also require tariff re-approval, land conversion or foreign-control clearance can extend considerably. The periods run from acceptance of a complete file, so incomplete submissions effectively reset the clock. Buyers should confirm the specific review period applicable to their sector with the relevant ministry before fixing a long-stop date.

Practical tips for navigating consent

• Pre-notification. An early, informal approach to the contracting authority flags the transaction and surfaces objections before they become deal-breakers.
• Regulatory walk-through meetings. Walking the authority through the buyer’s track record and intentions builds confidence and speeds formal review.
• File completeness. Treat the application as a single complete package; drip-feeding documents invites delay.
• Parallel processing. Where permissible, pursue investment-law and sectoral approvals concurrently rather than sequentially.

Due diligence on PPP projects: land, licences and finance (practical checklist)

Due diligence PPP Vietnam deals demands depth beyond a conventional corporate acquisition, because the value of a PPP or BOT asset is tied to a web of state consents, land rights and long-term contracts that can each unravel the economics if mishandled. The following checklist organises the review into five workstreams. The overarching PPP project acquisition Vietnam objective is to confirm that the rights being bought are secure, transferable and free of material encumbrance.

Land-use rights and title chains

Land is frequently the single highest-risk area. Review the complete title chain and establish:

• Whether the project land was allocated or leased, and on what terms and duration.
• Whether the land-use purpose has been correctly converted for infrastructure use, and whether any outstanding conversion steps remain with the provincial land authority.
• Whether any part of the land sits on public land requiring special transfer formalities.
• Existing encumbrances, mortgages, security interests and third-party claims registered against the land-use rights.
• Compensation and site-clearance status, which can expose a buyer to residual liabilities and local disputes.

Unclear conversion status or unregistered encumbrances over land-use rights PPP assets are among the most common reasons deals are repriced or abandoned.

Project licences and permits

Confirm that every operating permission is valid, transferable and in good standing:

• The investment registration certificate or equivalent approval and its current validity.
• Construction permits and completion/acceptance certificates for built assets.
• Operation permits and any sector-specific licences required to run the concession.
• Environmental approvals and compliance history, including any outstanding remediation obligations.

Contractual review

The concession agreement is the asset. Read it alongside every related project contract:

• The BOT/concession agreement itself, scope, duration, tariff mechanism, termination and compensation provisions, and change-of-control clauses.
• Engineering, procurement and construction (EPC) contracts and any outstanding contractor claims or warranties.
• Operation and maintenance (O&M) agreements and performance obligations.
• Tariff and revenue arrangements, including any authority powers to adjust tariffs unilaterally.

Finance and security

Most PPP and BOT projects are leveraged, and lenders hold significant leverage over any transfer:

• Review all loan agreements for change-of-control triggers, mandatory prepayment clauses and transfer restrictions.
• Identify every security interest, over shares, assets, land-use rights, revenue accounts and receivables.
• Confirm whether lender consent is a condition to the transfer and what the lenders will require to grant it.
• Assess intercreditor arrangements and any step-in rights that could affect the buyer’s control.

Where completion is to be conditioned on funding or security release, the mechanics are best handled through a structured escrow; the SPA Escrow (Vietnam), transactional escrow guide explains how release triggers can be tied to regulatory and lender consents.

Tax and customs exposure

Transfer of a project interest can crystallise material tax liabilities. Review:

• Value-added tax (VAT) treatment of the transfer structure.
• Capital-gains and withholding exposure on the disposal, particularly for offshore sellers.
• Transfer-pricing history where the target transacts with related parties.
• Any customs or import-duty incentives attached to project equipment that could be clawed back on a change of ownership.

Red flags to escalate

• Land-use rights that are unconverted, undocumented or heavily encumbered.
• Missing or conditional lender consents, or security that cannot be cleanly released or assumed.
• Contracting-authority powers to vary tariffs or terminate without adequate compensation.
• Material unresolved EPC or contractor disputes.
• Gaps in environmental or operating permits.

Deal structures & protections to reduce regulatory and title risk in PPP project acquisition Vietnam

Structure drives risk allocation. In a PPP project acquisition Vietnam context, the choice between buying shares, buying assets, or taking a staged step-in position determines which consents are triggered, which liabilities transfer, and how much protection the buyer retains after completion.

Asset versus share acquisition

A share acquisition keeps the project company, and therefore its licences, land-use rights and contracts, intact, which can avoid re-registration of individual permits. But it carries the full liability history of the company and almost always triggers change-of-control consents and foreign-investment approval. An asset acquisition can isolate unwanted liabilities, but requires separate transfer approvals for land, licences and key contracts, each of which may be refused or delayed. For most operating concessions, a share deal is the default, with warranties and indemnities managing historic-liability risk.

Contract novation versus assignment

Where the concession or related contracts are transferred directly, distinguish assignment from novation. Assignment transfers rights but may leave obligations with the original party; novation replaces the original contracting party entirely, releasing the seller and substituting the buyer. Counterparties, especially contracting authorities and lenders, frequently insist on novation so that the incoming investor assumes full, direct responsibility. The transfer of project rights Vietnam mechanism should be documented to match what the authority will actually approve.

Conditional completion mechanics

Because regulatory consents can take months, completion is typically conditioned on obtaining them. Escrow arrangements allow the buyer to commit funds while protecting against the risk that a consent is refused. Release triggers should be tied precisely to the issuance of the contracting authority’s consent, the line-ministry approval, the foreign-investment registration and any lender consent.

Warranties, indemnities and regulatory protections

Seller warranties should cover title to shares and land-use rights, validity of permits, the absence of undisclosed liabilities, and compliance with the concession. Specific indemnities are appropriate for identified risks such as tax exposure or pending disputes. Buyers should also negotiate protection against regulatory termination, for example, price adjustment or walk-away rights if a consent is refused or granted on materially adverse conditions.

Lender consent and intercreditor clauses

Where the project is financed, lender consent is usually a hard condition. Engage lenders early, understand their intercreditor and step-in rights, and build their consent into the conditions precedent. A lender refusal late in the process is one of the most damaging failure modes in infrastructure M&A.

Post-closing integration, regulatory filings and ongoing compliance

Completion is not the end of the regulatory process. A successful PPP project acquisition Vietnam transaction requires disciplined post-closing execution to perfect the transfer and maintain the concession in good standing.

Required post-transfer filings

After completion, the buyer must complete the registration formalities that give legal effect to the change of ownership and, where relevant, the contract transfer. This typically includes updating the enterprise registration and investment registration records with the competent authority, recording land-use-right changes with the land authority where applicable, and notifying the contracting authority and relevant line ministry of completion.

Employment and social insurance transitions

Operating concessions carry workforces. Confirm the treatment of employment contracts on transfer, ensure continuity of social-insurance contributions, and address any required notifications or consultations so that operations continue uninterrupted.

Ongoing reporting and breach management

Concession agreements impose continuing obligations, reporting, performance standards, and financial covenants under the loan documents. Establish a compliance calendar from day one, assign ownership of each obligation, and put in place a monitoring system so that early warning signs of breach are caught before they become termination events.

A practical 90-day post-closing checklist should include: completing all registry updates; notifying the contracting authority and lenders of completion; reconciling permit holders to the new ownership; onboarding the workforce; and standing up the ongoing compliance-reporting framework.

Practical timeline & sample checklist

The timeline below consolidates the workflow from pre-signing to the first year after completion. Treat the day ranges as planning estimates to be confirmed against the specific sector and ministry.

Comparison table: assignment and transfer requirements, BOT vs PPP vs BT

Note: the BT (Build-Transfer) model has been significantly constrained under successive reforms, and the terms on which new BT projects may be undertaken have changed; buyers should confirm the current status of the BT framework for any specific project.

Conclusion and next steps

A PPP project acquisition Vietnam deal in 2026 is achievable for well-prepared foreign buyers, but it rewards early planning and punishes shortcuts. The transaction succeeds or fails on three things: confirming eligibility and consent routes before signing; running deep due diligence on land-use rights, permits, contracts and financing; and building regulatory conditionality, escrow and strong warranties into the deal documents. Buyers who map the full approval chain, engage the contracting authority and lenders early, and condition completion on the consents they actually need are the ones who close on time and on terms.

The practical first move is a focused regulatory pre-check with experienced Vietnamese counsel, ahead of heads of terms, to shape the structure around the approvals the specific sector will require.
