Vietnam–China Disputes: Choosing VIAC, CIETAC or SIAC Arbitration

When a contract between a Vietnamese and a Chinese company breaks down, the first question experienced counsel asks is not “who is right” but: where will the dispute be decided, under whose procedural law, in what language — and will the final award be enforceable where the losing party’s assets are. Three institutions dominate arbitration clauses in Vietnam–China contracts: VIAC (Vietnam International Arbitration Centre), CIETAC (China International Economic and Trade Arbitration Commission) and SIAC (Singapore International Arbitration Centre). This article compares the three across eight dimensions — jurisdiction, rules, language, seat, costs, timing, and award enforcement in Vietnam and China under the 1958 New York Convention — with a decision matrix so businesses choose correctly at the drafting stage, not after the dispute erupts.

1. Why the choice of institution decides the dispute’s fate

Vietnam–China trade has a feature few bilateral relationships share: a wide institutional gap between the two legal systems, combined with enormous transaction volumes. Vietnamese companies sign sale, processing, distribution and joint-venture contracts with Chinese counterparties daily — and when disputes arise, each side instinctively wants its “home ground”: Vietnam for the Vietnamese party, China for the Chinese party.

In practice, three mistakes recur in Vietnam–China contracts:

• Leaving the dispute-resolution clause blank or drafting it in vague terms (“disputes shall be resolved by arbitration”). Once conflict erupts, the parties cannot agree on an institution, and the case stalls at the starting line.
• Choosing by habit or under drafting pressure without assessing whether the award can be enforced where the losing party holds assets. An unenforceable award is a paper victory.
• Ignoring the language and the seat of arbitration, which determine real-world cost (translation, interpretation, travel) and which procedural law governs the proceedings.

This article puts the three institutions on the same scale so businesses — and their counsel — can choose by analysis rather than instinct.

2. The three institutions at a glance

2.1. VIAC — Vietnam International Arbitration Centre

Established in 1993, VIAC is an independent arbitration body attached to the Vietnam Chamber of Commerce and Industry (VCCI) — the country’s oldest and most prominent commercial arbitration institution, handling both domestic and foreign-related disputes.

Its current procedural framework is the VIAC Rules of Arbitration (2026 edition), in force since 1 July 2026, applying to proceedings commenced from that date (previously the 2017 Rules, in force 1 March 2017 – 30 June 2026). The 2026 Rules renumbered several articles (seat 22→20, language 23→21, expedited procedure 37→24, mediation 29→34, interim measures 21→29, costs→39–41, arbitrator appointment→13–14); this article cites the 2026 numbering, with the corresponding 2017 number in brackets for legacy files. Notable features:

• Commencement: the claimant files a Request for Arbitration; the Centre forwards it to the respondent within 10 days of receiving the request, the arbitration agreement, supporting documents and arbitration costs (Articles 7–8, 2017 Rules).
• Defence: the respondent files its Statement of Defence within 30 days (Article 9, 2017 Rules).
• Expedited procedure: a dedicated chapter (Article 24, 2026 Rules; 2017 Rules: Article 37) for suitable cases.
• Mediation in arbitration: the tribunal may facilitate settlement (Article 34, 2026 Rules; 2017 Rules: Article 29).

VIAC’s greatest advantage for Vietnamese businesses: fees in Vietnamese dong, arbitrators who know Vietnamese law and business practice, and awards that count as domestic awards — enforceable directly in Vietnam without foreign-award recognition proceedings.

Recent figures show VIAC’s growing internationalisation: according to a 2026 Rajah & Tann analysis of VIAC data, VIAC handled 532 cases in 2025, of which 255 were foreign-related; the most frequent foreign-party origins were Singapore (36), China including Hong Kong (16), the United Kingdom (6) and Thailand (4). In other words, VIAC already has meaningful experience with China-related cases — a material data point when businesses ask whether a Vietnamese institution can handle a Chinese element.

2.2. CIETAC — China International Economic and Trade Arbitration Commission

Founded in 1956 under the China Council for the Promotion of International Trade (CCPIT), CIETAC (中国国际经济贸易仲裁委员会) is among the world’s highest-volume arbitration institutions, operating through sub-commissions in Beijing, Shanghai, Shenzhen, Tianjin, Chongqing, Hong Kong and other centres.

The current CIETAC Arbitration Rules 2024 were adopted on 2 September 2023 and took effect on 1 January 2024. The 2024 revision pushes internationalisation further: clearer language provisions, more flexible procedure, and expanded support for ad hoc arbitration as Chinese law reforms.

A landmark development: China’s revised Arbitration Law was adopted on 12 September 2025 and has been in force since 1 March 2026 — described by observers as the most comprehensive overhaul since the law’s inception. The enacted provisions most relevant to Vietnam–China disputes: (i) Article 27 — a “deemed arbitration agreement” mechanism: where one party applies for arbitration and the other raises no written objection to the agreement’s validity before the first hearing, an arbitration agreement is deemed to exist; (ii) Article 81 — first formal recognition of the “seat of arbitration” for foreign-related cases; (iii) Article 82 — limited ad hoc arbitration permitted; (iv) Article 72 — the window for applying to set aside an award cut from six months to three months; (v) broadened interim measures. Parties signing long-term contracts should review existing arbitration clauses against the law as in force.

CIETAC’s strength in Vietnam–China disputes is convenience for the Chinese side (Chinese language, Chinese seat, arbitrators versed in Chinese law) and smooth enforcement in China, where most Chinese companies hold their assets.

2.3. SIAC — Singapore International Arbitration Centre

Founded in 1991, SIAC has become one of the world’s preferred institutions for cross-border commercial disputes in Asia. Singapore is prized by the international bar for its modern arbitration legislation (based on the UNCITRAL Model Law), a firmly pro-arbitration judiciary, and neutrality between Asian parties.

The current SIAC Arbitration Rules 2025 (7th edition) took effect on 1 January 2025. Key innovations:

• Streamlined Procedure (Rule 13, Schedule 2): applies where the amount in dispute does not exceed SGD 1 million before the tribunal is constituted (a party may apply to the President to exclude it) or where the parties agree; sole arbitrator; award within 3 months from the constitution of the tribunal unless extended; tribunal and SIAC fees capped at 50% of the Schedule of Fees maxima.
• Emergency Arbitration: available before, with, or after filing the Notice of Arbitration but prior to tribunal constitution; the 2025 Rules permit ex parte preliminary protective orders in defined circumstances.
• Filing fee: SGD 3,270 for Singapore parties (including 9% GST) and SGD 3,000 for overseas parties — non-refundable.

SIAC’s strength is neutrality widely regarded by the international bar as high — neither side enjoys home advantage — plus an international arbitrator pool and world-class procedure. The corresponding weakness is the highest cost of the three.

4. Key differences in detail

4.1. Validity of the arbitration agreement — the “vague clause” trap in China

This is the most consequential yet most overlooked difference. Under Vietnamese law (Article 16, Law on Commercial Arbitration 2010), the agreement must be in writing — normally satisfied by an arbitration clause in the signed contract.

Chinese law is stricter: the agreement must designate a specific arbitration commission. Chinese courts have long treated clauses such as “disputes shall be arbitrated in Beijing/Shanghai” — naming no institution — as at risk of invalidity. An invalid arbitration agreement is catastrophic: the claimant loses the arbitral forum, and the case may end up in court — typically where the respondent sits, i.e., the other side’s home ground.

Practice point: every Vietnam–China contract should name the institution in full (e.g., “China International Economic and Trade Arbitration Commission (CIETAC)”), with applicable rules, seat and language. Never abbreviate. China’s revised Arbitration Law — in force since 1 March 2026 — modernises the validity rules, including a “deemed arbitration agreement” mechanism (Article 27): a vague clause survives where the other party raises no written objection to its validity before the first hearing. That is a passive safety net, not a drafting strategy: the robust course is still to draft tightly under the law as in force — name the institution, rules, seat and language expressly.

4.2. Language — the largest hidden cost

Language is the hidden cost businesses most underestimate. A Chinese-language arbitration for a Vietnamese team that cannot work in Chinese means: all evidence translated and notarised, interpreters at every hearing, and counsel working through a linguistic intermediary — cost and error risk both multiply.

• VIAC (Article 21, 2026 Rules; 2017 Rules: Article 23): a clean split. No foreign element — Vietnamese. Foreign element (the typical Vietnam–China case) — as agreed; otherwise the tribunal decides, considering the circumstances including the contract language. Where the contract is in Vietnamese or bilingual Vietnamese–English, a Vietnamese or English-language proceeding is the likely outcome.
• CIETAC (Article 84, 2024 Rules): Chinese is the default unless CIETAC considers another language more appropriate or the tribunal designates otherwise. Without agreement, a CIETAC case seated in China will very likely run entirely in Chinese.
• SIAC: as agreed; otherwise the tribunal decides. English is the practical default for Vietnam–China cases at SIAC.

Practice point: agree the language in the clause itself. Common options for Vietnam–China contracts: Vietnamese (VIAC, where the Vietnamese side has leverage), English (the neutral option, especially at SIAC), or bilingual (most expensive — reserve for genuine need).

4.3. The seat — what determines the procedural law and annulment forum

The “seat” is not the geographic hearing venue but the juridical anchor: the procedural arbitration law of the seat governs the proceedings, and that jurisdiction’s courts alone can annul the award. Leaving the seat blank is among the costliest drafting errors.

• VIAC: Article 20 (2026 Rules; 2017 Rules: Article 22) — as agreed; otherwise the tribunal fixes an appropriate seat. In practice, Hanoi or Ho Chi Minh City.
• CIETAC: typically China (the administering CIETAC seat/sub-commission). Agree expressly.
• SIAC: as agreed; in practice typically Singapore — among the world’s most respected seats (International Arbitration Act based on the UNCITRAL Model Law, reliably pro-arbitration courts).

Practice point: never leave the seat blank.

4.4. Costs on a common scale

Arbitration costs have three layers: (1) institution filing/registration and administration fees; (2) tribunal fees; (3) party costs (counsel, translation, travel, experts). Institutions publish (1) and (2); layer (3) usually dominates and depends on the parties’ choices.

Official schedules (checked September 2026):

• SIAC: SGD 3,000 filing fee for overseas parties (non-refundable); minimum SGD 5,000 administration fee for ordinary cases; ad valorem tribunal fees. Institutional costs for a mid-value case typically run into the tens of thousands of SGD — before international counsel fees, usually the largest line item.
• CIETAC: ad valorem arbitration fee (e.g., disputes up to RMB 1 million — 4%, minimum RMB 10,000; the rate steps down as value rises) — plus a separate RMB 10,000 registration fee charged on acceptance. Materially cheaper than SIAC.
• VIAC: fees in VND under VIAC’s published schedule (registration plus ad valorem fees). For the same amount in dispute, VIAC is generally the most economical — especially with no translation/interpretation cost for Vietnamese-language proceedings and no international travel.

Caveat: budget all three layers, not just the filing fee. An SIAC case with international counsel can cost multiples of the institutional fees.

4.5. Timing — who can commit to a schedule?

• CIETAC sets an award deadline in its Rules: 6 months from tribunal constitution, excluding suspensions (a general provision of Article 51, not limited to international cases). A summary procedure exists for simple, low-value cases.
• SIAC (2025 Rules, Rule 13 / Schedule 2) offers the Streamlined Procedure: applies to disputes up to SGD 1 million (before tribunal constitution) or by party agreement, with award within 3 months of the tribunal’s constitution unless extended, a sole arbitrator and fees capped at 50% of the maxima — the clearest committed timeline of the three for modest-value disputes.
• VIAC sets no hard deadline in its Rules; timing depends on the tribunal and complexity. Practitioner experience suggests roughly 6–12 months for ordinary cases. Article 24 (2026 Rules; 2017 Rules: Article 37) provides an expedited procedure for suitable matters.

All three provide emergency arbitration / interim measures for urgent situations (e.g., asset dissipation) — VIAC tribunals may order interim measures (Article 29, 2026 Rules; 2017 Rules: Article 21).

4.6. Enforcement in Vietnam and China — the final exam

An unenforceable award is worthless. Businesses should assess enforcement before signing, not after winning.

Common foundation: the 1958 New York Convention, with 170+ member states:

• Vietnam acceded on 12 September 1995 (effective 11 December 1995) with three declarations: (1) applies only to awards made in another Contracting State (non-Contracting-State awards: on a reciprocity basis); (2) the “commercial” reservation — only disputes arising from relationships considered commercial under Vietnamese law; (3) interpretation before Vietnamese courts per Vietnam’s Constitution and law.
• China: Convention effective 22 April 1987, with reciprocity and commercial reservations (per the 1987 Supreme People’s Court Notice).

Practical consequences per pair:

Three practical notes:

1. Recognition is a separate proceeding costing months and counsel fees. If the likely losing party’s assets are mainly in Vietnam, VIAC (domestic award, direct enforcement) has a clear edge — and symmetrically for CIETAC with assets in China.
2. The “commercial” reservation: both Vietnam and China limit the Convention to commercial disputes. Typical Vietnam–China sale, processing, distribution and JV contracts qualify; borderline non-commercial disputes need counsel’s assessment.
3. China’s “prior reporting” system: a lower Chinese court wishing to refuse a foreign award must report to the Supreme People’s Court — in practice a meaningful check on arbitrary refusals, and a plus for enforcing VIAC/SIAC awards in China.

5. Similarities worth noting

• All three are institutional (not ad hoc) arbitrations with full administrative machinery, arbitrator panels and complete rules.
• All awards are final — no appeal; the only control is annulment before the courts of the seat, on limited statutory grounds.
• Vietnam, China and Singapore are all New York Convention members — cross-enforcement rests on the multilateral framework, not bilateral treaties.
• All three respect party autonomy on tribunal size (one or three), language, seat and governing law — provided the parties agree expressly and early.
• All three offer fast-track procedures for small/simple cases and emergency/interim relief, differing only in labels and thresholds.

6. Decision matrix

There is no absolutely “best” institution — only the best fit for each scenario:

Golden rule: decide at the drafting stage — based on where assets sit, what language your team works in, and your budget — not after the dispute erupts. A good clause is one both sides find acceptable even imagining themselves as the future losing party.

7. Six recurring risks in Vietnam–China cases

Risk 1 — Vague clauses naming no institution. Symptom: “disputes shall be resolved by arbitration in China.” Cause: copying generic templates without understanding China’s designated-commission requirement. Prevention: name the institution in full, plus rules, seat, language and tribunal size.

Risk 2 — An adverse language default. Symptom: accepting CIETAC at the Chinese side’s suggestion without agreeing language — proceedings run in Chinese; the Vietnamese side bears all translation/interpretation costs. Cause: assuming “international arbitration means English” — wrong at CIETAC (Chinese default, Art. 84, 2024 Rules). Prevention: agree the language in the clause; if CIETAC with English is wanted, state it expressly.

Risk 3 — Blank seat. Symptom: the clause names the institution but no seat. Cause: assuming the seat follows automatically. Consequence: the procedural law and annulment forum default under institutional rules — possibly not as expected. Prevention: always state the seat (e.g., “Seat of arbitration: Singapore”).

Risk 4 — Under-budgeting SIAC. Symptom: looking only at the SGD 3,000 filing fee while tribunal fees (ad valorem), international counsel, translation and Singapore travel dominate. Cause: comparing list prices instead of total cost of ownership. Prevention: budget all three cost layers; for modest values consider VIAC or fast-track procedures.

Risk 5 — “Winning is the end.” Symptom: winning a CIETAC/SIAC award, then spending months and counsel fees on recognition before a Vietnamese provincial People’s Court. Cause: confusing domestic awards (direct enforcement) with foreign awards (Convention recognition required). Prevention: map the counterparty’s assets at drafting stage and prefer the institution whose awards are “domestic” where those assets sit.

Risk 6 — Ignoring the “commercial” reservation. Symptom: assuming every foreign award is recognisable. Cause: unawareness that Vietnam and China both limit the Convention to commercial disputes. Prevention: for borderline commercial/non-commercial disputes (internal corporate disputes, personality-rights elements), take counsel’s advice before choosing the forum.

A note for Chinese businesses operating in Vietnam: among the six risks above, Risks 2, 3 and 5 are precisely the traps Chinese companies in Vietnam most often fall into — applying domestic-deal habits to cross-border clauses. The cost of a pre-signing clause review is always lower than the cost of post-dispute remediation.

8. Practical guidance for drafting the clause

Before signing (negotiation stage):

1. Map the assets: where does each side hold plants, bank accounts, goods? Prefer the institution whose awards are domestic where the likely losing party’s assets sit.
2. Lock five elements: (i) institution’s full name; (ii) applicable rules (with version); (iii) seat; (iv) language; (v) tribunal size (one or three) and the governing law of the contract.
3. Start from the institutions’ model clauses (VIAC, CIETAC and SIAC all publish them) and adjust the five elements — rather than drafting from scratch.

Model framework (adapt with counsel before use):

“Any dispute arising out of or in connection with this Contract shall be finally resolved by arbitration at [VIAC/CIETAC/SIAC] in accordance with [the VIAC Rules of Arbitration / the CIETAC Arbitration Rules 2024 / the SIAC Arbitration Rules 2025]. The seat of arbitration shall be [Hanoi/Ho Chi Minh City/Beijing/Shanghai/Singapore]. The language of arbitration shall be [Vietnamese/Chinese/English]. The tribunal shall consist of [one/three] arbitrator(s). The governing law of the Contract shall be [Vietnamese/Chinese/third-country] law. The award shall be final and binding on the parties.”

After a dispute erupts:

4. Re-examine the clause immediately — validity (is an institution named? does it meet the formal requirements of the enforcement jurisdiction?) — before filing.
5. Weigh arbitration against negotiation/mediation in parallel. In long-term Vietnam–China relationships (supply chains, processing), a wise settlement can outweigh a won award that kills the partnership.
6. Prepare enforcement early: at the first sign of success, map the losing party’s assets in the enforcement jurisdiction and prepare the recognition file (original/certified arbitration agreement and award) — do not wait for the award to start learning the procedure.
