Chinese general contractors in Vietnam increasingly take on EPC (engineering–procurement–construction) packages in industrial parks, energy and infrastructure. Yet an EPC contract that works in China cannot simply be transplanted to Vietnam: Vietnam manages foreign contractors through per-package licenses, mandates consortium with Vietnamese contractors, and applies its own warranty, price-adjustment and penalty rules. This article compares the two legal frameworks and flags the five contract risks Chinese general contractors most often face in Vietnam.

Table of contents

1. Context: why compare before signing

For a Chinese contractor, Vietnam looks familiar — similar project culture, competitive pricing, fast-growing demand. The legal systems, however, diverge at the structural level. China runs a unified 资质 (qualification) regime: an enterprise holding the right 资质 may undertake projects without per-project licensing. Vietnam requires every foreign contractor to obtain a Construction Operation License for each package (Decree 212/2026/ND-CP), and forces a consortium with a Vietnamese contractor or the use of Vietnamese subcontractors (Article 43). A contractor that prices and schedules a Vietnamese EPC package on Chinese assumptions — "we have the capability, we can start" — typically discovers the licensing timeline only after signing. The sections below map each divergence to a concrete contract clause.

2. Six structural differences

The six points below are where Chinese general contractors in Vietnam stumble most often when they bring domestic-contract thinking to a Vietnamese project. Each is tied to a specific rule in Vietnamese or Chinese law and a matching practical recommendation.

2.1. Per-package licensing (Vietnam) vs the 资质 system (China)

This is a structural difference. Vietnam does not recognize a foreign contractor's "general capability": for each package, the Chinese contractor must obtain a separate Construction Operation License. The application is tied to the specific bid-winning or contractor-selection decision for that package (Articles 43–44, Decree 212/2026/ND-CP). The license expires with the package.

China operates the 资质 system: construction enterprises are certified by type (施工总承包, 专业承包, etc.) and grade; holding the right 资质, they may undertake corresponding projects without per-project licensing. The practical consequence: Chinese general contractors new to Vietnam routinely underestimate the licensing process — signing the contract first, then applying — while Vietnamese law requires the owner to sign the contract only after the foreign contractor already holds the license. The correct sequence is: bid winning/selection → license application → contract signing → mobilization.

2.2. Mandatory "localization": the Vietnamese consortium duty

Article 43 of Decree 212/2026/ND-CP imposes a condition Chinese general contractors rarely meet at home: the contractor must form a consortium with a Vietnamese contractor or use Vietnamese subcontractors, with the Vietnamese side's scope, volume and value clearly defined in the dossier. The only exception — no domestic contractor capable of any part of the package — is narrow and hard to prove in practice.

China has no comparable mandatory consortium duty for domestic contractors; subcontracting is the contractor's own decision within Article 791 of the Civil Code (no subcontracting to entities lacking 资质, no re-subcontracting, main structures self-performed). So in Vietnamese EPC negotiations, the Chinese general contractor must plan from day one: who the Vietnamese consortium partner is, how scope and warranty liability are split — instead of defaulting to "take it all, sort it out later".

2.3. When an EPC package may be tendered

China regulates project "maturity" before EPC tendering in some detail: state-funded projects are in principle tendered only after preliminary design (初步设计) approval; enterprise-funded projects after investment 核准 or 备案 procedures (Articles 7–8 of the 2019 Measures). The logic: the scope must be defined enough for a lump-sum bid.

Vietnam sets no equivalent "maturity threshold" in current construction law; EPC contractor selection follows each project's tendering process. In practice, a Vietnamese EPC contract may be signed on the basis of basic design (equivalent to FEED), with detailed design performed afterward by the general contractor — Decree 210/2026/ND-CP even assigns the employer duties to review and approve post-basic-design drawings promptly for EPC contracts. Vietnamese owners should understand: the earlier the EPC is signed, the tighter the contract's design-change management mechanism must be.

2.4. Money and cash flow: 30% advance, no 垫资, late-payment interest

Three numbers Chinese general contractors should memorize for Vietnam:

  • Advance capped at 30% of the contract price at signing (Decree 210/2026/ND-CP). In China, advance ratios are set by agreement and project practice, with no general hard cap.
  • China bans demanding 垫资 (contractor self-financing) in state-funded projects — a contractor-protection rule. Vietnam has no directly equivalent ban, but advance and progress-payment mechanisms in construction contracts are mandatory subjects of agreement.
  • Late-payment interest: Clause 5, Article 28 of Decree 210/2026/ND-CP obliges the employer to pay interest on late payments as prescribed and as agreed. Chinese general contractors should quantify in the contract: the applicable rate, the accrual date — rather than leaving it to "as prescribed by law".

2.5. Warranties: simple 12/24 months vs design-life structural warranty

Vietnam opts for a simple, administrable frame: 24 months (special-grade/grade-I works, public capital), 12 months (other grades, public capital), with minimum warranty bonds of 3%–5% of contract value. Private-capital works (most FDI projects) may refer to these levels — room for negotiation, but the reference frame is clear.

China is far more detailed: main structures and foundations warranted for the reasonable service life stated in the design documents (often 50 years for residential buildings), waterproofing 5 years, electrical/plumbing 2 years. There is also the 缺陷责任期 (defects liability period, typically 6/12/24 months by agreement) — after which the contractor may demand return of the quality bond. The real risk: a Chinese general contractor used to long design-life structural warranties may discount Vietnam's "short" 12/24-month warranty, but it is the 3%–5% warranty money retained that bites cash flow directly.

2.6. Governing law and the "imported template" trap

The non-negotiable principle: construction on Vietnamese territory is governed by Vietnamese law. Clause 2, Article 42 of Decree 212/2026/ND-CP requires foreign contractors to comply with Vietnamese law and Vietnam's international treaties. Parties may freely agree on dispute resolution (Article 17, Decree 210/2026/ND-CP: negotiation → mediation → arbitration/courts), but cannot contract out of mandatory rules on licensing, labour safety, quality, acceptance and warranties.

The most common trap is transplanting an EPC template used in China (or a FIDIC Silver Book adapted to Chinese practice) into Vietnam without a compatibility review: subcontracting clauses may clash with the Article 43 consortium duty; warranty clauses may miss the minimum warranty bond; penalty clauses may exceed the 12% cap for public/PPP projects (Clause 3, Article 86, Construction Law 2025), voiding the excess. Since 01/7/2026, the Ministry of Construction has also issued 07 construction contract templates including an EPC template in Appendix VII of Decision 1040/QD-BXD — a useful negotiation reference.

3. Notable similarities

Not everything differs. Three similarities help both sides find common ground faster:

  • Full responsibility of the general contractor: both systems place the EPC general contractor in full charge of quality and schedule (China expressly adds safety and cost). The owner deals with a single point of contact.
  • No wholesale transfer: China prohibits 转包 of the entire works and re-subcontracting (Article 791, Civil Code); Vietnam likewise attaches the general contractor's responsibility to the whole contracted scope, with subcontracting subject to the contract and the law. The "sign then dump it all" mindset is unacceptable in both countries.
  • Competitive tendering for state funds: both Vietnam (Bidding Law 22/2023/QH15) and China (招标投标法) require competitive bidding for state-funded projects — common ground investors from both countries can picture.

4. Five contract risks for Chinese general contractors in Vietnam

Risk 1 — Working before holding the Construction Operation License. Symptoms: signing the EPC contract then applying for the license, or using one package's license to "cover" a new package. Cause: 资质 thinking — "we have general capability, we can work". Prevention: make the license a condition precedent — the contract takes construction effect only after the license is granted; allocate who bears delay costs if the license is refused.

Risk 2 — Ignoring the Vietnamese consortium duty. Symptoms: the EPC contract shows the Chinese general contractor performing 100% of the scope, with no Vietnamese consortium member. Cause: the independent-general-contractor habit in China and reluctance to share know-how. Prevention: identify the Vietnamese partner at the bidding stage; define scope, value, warranty liability and internal dispute mechanisms in the consortium agreement; avoid the owner discovering the breach mid-construction.

Risk 3 — A rigid lump-sum price with no adjustment valve. Symptoms: a lump-sum EPC copied from Chinese practice, with no adjustment mechanism for material price swings, scope changes or force majeure. Cause: the two systems' price-adjustment philosophies differ — Vietnamese law permits lump-sum adjustment only in narrow cases (force majeure, fundamental change of circumstances, scope change). Prevention: list price-adjustment events, formulas and variation procedures (site minutes, construction logs) in the contract.

Risk 4 — Underestimating warranties and warranty money. Symptoms: the contractor budgets warranty costs on Chinese practice, then is surprised when the Vietnamese owner retains 3%–5% of contract value as warranty money. Cause: in China, the quality bond is returned after the 缺陷责任期 (typically 6–24 months); in Vietnam, warranty money is tied to the 12/24-month warranty and returned only when the obligation ends. Prevention: negotiate the return timing, deduction conditions, and replacement by a warranty bond to free up cash flow.

Risk 5 — Over-cap penalties and partially void imported clauses. Symptoms: a contract applying 0.1%/day delay penalties with no cap, or importing Chinese-style exemption clauses. Cause: unawareness of the 12% cap for public-investment/PPP projects (Clause 3, Article 86, Construction Law 2025) and Vietnam's Civil Code limits on penalties (Article 418). Prevention: review all penalty, compensation and exemption clauses under Vietnamese law before signing; for public/PPP projects, stay within the statutory cap and use progress bonuses instead of heavy penalties.

5. Practical recommendations

Before signing the contract:

  1. Check the licensing timeline: confirm the package has a bid-winning/selection decision, prepare the Construction Operation License dossier immediately, and make the license a condition precedent to the commencement order.
  2. Lock in the Vietnamese consortium partner early; sign a consortium agreement clearly dividing scope, value, warranty liability and internal dispute resolution.
  3. Review the template's compatibility with Vietnamese law: penalties, warranties, warranty money, price adjustment, governing law. Reference the EPC template in Appendix VII of Decision 1040/QD-BXD.

During performance:

  1. Manage variations in writing: every design, quantity and schedule change documented in minutes, construction logs and party confirmations at once — decisive evidence if prices must later be adjusted or disputes resolved.
  2. Comply with foreign-contractor duties: labour and equipment as committed in the license dossier; the owner supervises this, so cooperate rather than evade.

When disputes arise:

  1. Prioritize negotiation and mediation within the contractual time limits before escalating; keep an evidence file ready (contract, appendices, acceptance minutes, logs, correspondence). For major disputes, consider an arbitration clause at drafting stage instead of defaulting to courts.

6. Frequently asked questions

What licenses does a Chinese general contractor need to perform EPC work in Vietnam?

Under Clause 1, Article 42 of Decree 212/2026/ND-CP, a foreign contractor may only carry out construction activities in Vietnam after being granted a Construction Operation License by the state construction authority. Requirements include a bid-winning or contractor-selection decision from the project owner/prime contractor, and a consortium with a Vietnamese contractor or the use of Vietnamese subcontractors (Article 43), unless no domestic contractor is capable of any part of the package. The owner may only sign the contract after the foreign contractor holds the license.

What is the core difference between EPC contracts in Vietnam and China?

The core difference lies in state management. Vietnam manages foreign contractors through per-package licenses (Decree 212/2026/ND-CP), while China uses the 资质 system — unified qualification certificates; only enterprises holding the corresponding 资质 may undertake projects. Both systems treat EPC as the general contractor's full design–procurement–construction responsibility, but tendering, payment, warranty and dispute rules differ substantially, so a contract template from one side cannot be transplanted to the other.

How long is the warranty period for EPC works under current Vietnamese law?

Under Decree 207/2026/ND-CP (effective 01/7/2026), warranty runs from the owner's acceptance: at least 24 months for special-grade and grade-I works using public/state-budget capital, and at least 12 months for other grades using such capital; other funding sources may refer to these levels. For public capital, the minimum warranty bond is 3% of the contract value (special-grade/grade I) and 5% (other grades). China, by contrast, warrants main structures for the reasonable service life stated in the design documents, waterproofing for 5 years, and electrical/plumbing systems for 2 years.

Which law governs an EPC contract with a Chinese general contractor in Vietnam?

As a rule, construction on Vietnamese territory is governed by Vietnamese law — Clause 2, Article 42 of Decree 212/2026/ND-CP requires foreign contractors to comply with Vietnamese law and the international treaties Vietnam has joined. The parties may agree on dispute resolution (negotiation, mediation, arbitration, courts under Article 17 of Decree 210/2026/ND-CP), but cannot contract out of mandatory Vietnamese rules on licensing, safety, quality and warranties.

May a Chinese general contractor subcontract the entire EPC works?

No — in both systems. In China, Article 791 of the Civil Code prohibits a contractor from transferring the entire contracted works to a third party, prohibits subcontracting to entities lacking the required 资质, and prohibits re-subcontracting; the main structures must be built by the contractor itself. In Vietnam, EPC contracts likewise attach full responsibility to the general contractor; subcontracting must follow the contract and the law, and foreign contractors additionally face the consortium/Vietnamese-subcontractor duty under Article 43 of Decree 212/2026/ND-CP.

Need a lawyer who understands both systems?

An EPC contract with a Chinese general contractor is where Vietnamese construction law meets Chinese general-contractor practice — and where risks arise fastest if clauses are not carefully "translated" in legal terms.
