Vietnam has become one of the most attractive destinations for Chinese investment, particularly in industrial parks, factories, infrastructure projects, and EPC construction works. While market opportunities are significant, construction projects in Vietnam also carry high legal and operational risk—especially at the contract stage.

For Chinese investors, many disputes do not arise from bad faith, but from misunderstanding Vietnamese law, local practice, and enforcement realities. Once a dispute occurs, correcting contractual mistakes becomes expensive and time-consuming.

Understanding what to watch for before signing a construction contract is therefore essential.

Construction Contracts in Vietnam Are Highly Regulated

Unlike simple commercial contracts, construction contracts in Vietnam are governed by a combination of:

  • Civil law

  • Construction law

  • Tendering and project regulations

  • Technical standards and licensing rules

Foreign investors often underestimate how mandatory regulations interact with contract freedom. Even if both parties agree contractually, certain clauses may be unenforceable if they contradict Vietnamese law.

Early legal review ensures the contract aligns with both commercial intent and legal requirements.

Contractor Licensing and Legal Capacity Must Be Verified

One of the most common risks for Chinese investors is signing contracts with unqualified or improperly licensed contractors.

Key issues include:

  • Whether the Vietnamese contractor holds the correct construction license

  • Whether the license scope matches the project type

  • Whether subcontracting is legally permitted

If the contractor lacks proper licensing, the contract may be unenforceable—or worse, the project may be suspended by authorities.

Verifying legal capacity before signing is critical.

Scope of Work Must Be Defined With Precision

Construction disputes often arise from vague or incomplete descriptions of work scope.

Common problems include:

  • Unclear division between main contractor and subcontractors

  • Missing technical standards

  • Ambiguous responsibility for materials or equipment

  • Informal changes during execution

Vietnamese courts and arbitral tribunals rely heavily on written contractual terms, not assumed industry practice. A poorly defined scope creates serious enforcement risk.

Payment Structure and Milestones Require Careful Design

Payment disputes are among the most frequent construction conflicts in Vietnam.

Chinese investors should pay close attention to:

  • Clear payment milestones linked to verifiable progress

  • Retention and release conditions

  • Payment currency and method

  • Consequences of delayed or disputed payments

Improper payment structures often trigger disputes that halt projects and escalate costs.

Time for Completion and Delay Liability Must Be Clear

Delays are common in construction projects—but how delays are handled legally matters.

Contracts should clearly address:

  • Completion deadlines

  • Extensions of time

  • Liquidated damages for delay

  • Circumstances excusing delay

Without clear rules, delay disputes become subjective and difficult to resolve.

Variations and Change Orders Are a Major Risk Area

In Vietnam, many construction disputes arise not from original contract terms, but from variations during execution.

Chinese investors should ensure that:

  • Variation procedures are clearly defined

  • Approval authority is specified

  • Cost and time impact are documented

Informal approvals or verbal instructions often lead to disputes that are difficult to prove later.

Performance Bonds and Guarantees Are Crucial

Security mechanisms play a key role in protecting investors.

Important considerations include:

  • Performance bonds issued by acceptable banks

  • Advance payment guarantees

  • Conditions for calling guarantees

Many investors only realize the importance of these tools after disputes arise—when it is already too late.

Governing Law and Dispute Resolution Clauses Are Strategic Decisions

Choosing dispute resolution mechanisms should never be an afterthought.

Chinese investors must consider:

  • Whether Vietnamese law or foreign law applies

  • Whether disputes are resolved by arbitration or court

  • Where awards or judgments can be enforced

A favorable decision that cannot be enforced has little commercial value.

Language of the Contract Matters More Than Expected

Vietnamese authorities and courts operate in Vietnamese.

If contracts are bilingual:

  • The prevailing language must be specified

  • Translation accuracy must be ensured

Disputes often arise when legal meaning changes between languages. Poor translation can undermine otherwise strong legal positions.

Termination Rights Must Be Carefully Drafted

Improper termination is a common and costly mistake.

Contracts should clearly specify:

  • Grounds for termination

  • Required notice procedures

  • Consequences of termination

Terminating incorrectly can expose the investor to counterclaims—even if the contractor is at fault.

Enforcement Reality Must Be Considered From the Start

Chinese investors often focus on winning disputes rather than enforcing outcomes.

Before signing, it is important to assess:

  • Whether the contractor has enforceable assets

  • Whether guarantees can be enforced in Vietnam

  • Whether arbitration awards will be recognized

Enforcement planning should start at the contract stage, not after disputes arise.

Why Many Chinese Investors Face Construction Disputes in Vietnam

In practice, disputes often occur because:

  • Contracts are based on foreign templates without localization

  • Legal review is skipped to save time

  • Risk allocation is unclear

  • Ongoing legal monitoring is absent

These issues are preventable with proper legal involvement.

Why One-Time Legal Review Is Often Not Enough

Many investors engage lawyers only at contract signing.

However, construction projects evolve over time. Without continuous legal support:

  • Variations go undocumented

  • Payment risks increase

  • Termination decisions become risky

Construction projects require ongoing legal oversight, not just initial review.
