Choosing Arbitration: VIAC (Vietnam) vs SIAC (Singapore) for FDI Disputes

Of all the pairings in this series, VIAC against SIAC shows the starkest gap in international standing: one is the centre of the host investment country itself, the other is Asia’s flagship arbitration institution seated in Singapore. But standing does not win cases by itself — where the enforcement assets sit decides most FDI disputes in Vietnam. This article weighs those two scales for the Vietnam–Singapore pairing, kept separate from the other comparisons.

Legal basis

On the Vietnamese side the frame is the Law on Commercial Arbitration 54/2010/QH12 and VIAC with its own rules; a VIAC award is a domestic award, enforced directly through Vietnamese enforcement authorities. On the Singapore side, SIAC operates under the SIAC Rules, 7th edition, effective 1 January 2025, with mechanisms such as emergency arbitrators, streamlined and expedited procedures by dispute value, and a professional registrar system in Singapore — a mature arbitral jurisdiction with a pro-arbitration apex court.

Both countries are parties to the 1958 New York Convention — Singapore since 1986, Vietnam since 1995 — so a SIAC award is recognised in Vietnam through the procedure in the Civil Procedure Code 92/2015/QH13 from Article 423, and a VIAC award is recognised in Singapore under that country’s law.

Applied analysis

SIAC is strong on depth in complex investment and commercial cases, an international arbitrator bench, capacity for multi-party and multi-contract cases, and absolute perceived neutrality where one side is a Vietnamese State enterprise or agency. The price is total cost: SIAC fees, hourly arbitrator fees and Singapore counsel fees sit in the region’s top band, and a Vietnamese team is still needed for the in-country evidence and assets.

VIAC wins on three practical points: cost several times lower at the same dispute size; no recognition layer where assets are in Vietnam; and seamless interim and asset-preservation measures with Vietnamese courts. Its weakness is that for very large disputes structured in layers through Singapore, foreign parties often refuse VIAC over experience and predictability concerns — a negotiation problem, not an absolute quality verdict.

Recommended actions

The working decision rule: if the centre of interest and enforcement assets are in Vietnam and the amount is mid-sized, VIAC with an international presiding arbitrator is enough. If the deal is structured through a Singapore holding, has several foreign parties, or one side is a Vietnamese public entity making neutrality a precondition, SIAC is a rational price. In both cases, anchor interim measures in Vietnam inside the clause itself.

The Malaysia AIAC pairing is handled in EXP-3218 in this same batch, and the Philippines PDRCI pairing is the published EXP-3219 on flaw.vn — the three articles are delineated by counterparty and do not share one conclusion frame.

Frequently Asked Questions

Strengths and weaknesses of VIAC vs SIAC in investment disputes?

VIAC is strong on cost, direct enforcement in Vietnam and in-country asset preservation; it is weaker on depth for large-scale international investment disputes and on predictability in foreign counterparties’ eyes. SIAC is strong on international standing, the 7th-edition Rules effective 2025 with streamlined and emergency mechanisms, and a global arbitrator bench; it is weak on very high total cost and on the recognition step still needed in Vietnam where assets sit there. The right choice follows where the assets are and how complex the dispute truly is, not reputation alone.

Arbitration costs and duration in each place?

Fees at both institutions scale with the amount in dispute under each centre’s schedule, so there is no fixed figure; relatively, a SIAC case commonly costs several times a VIAC case once hourly arbitrator fees, administrative charges and Singapore counsel are added. On time, an ordinary case at either forum runs roughly one to two years to an award; SIAC’s 2025 Rules add streamlined tracks for lower-value disputes, while choosing SIAC for Vietnamese assets adds recognition time at a Vietnamese court.

Enforcement of arbitral awards in each country (New York Convention)?

Both Vietnam and Singapore are parties to the 1958 New York Convention, so each forum’s award is recognised and enforced in the other country through its courts. In Vietnam a SIAC award passes the foreign-award recognition procedure in the Civil Procedure Code 92/2015/QH13 from Article 423, refusable only on the Convention’s narrow grounds. A VIAC award enforced in Vietnam needs no such procedure. In Singapore, a VIAC award is enforced under Singapore’s international arbitration law as an award from a Convention country.

Model arbitration clause for contracts with Thai partners? Recommendation to check local counsel for foreign law details.

The model clause should state: the chosen institution — VIAC or SIAC; the seat; the language; the number of arbitrators and how the presiding arbitrator is chosen; the governing law; and an interim-measures arrangement where the assets are. This series’ canon question uses a Thai-partner template, but for a Singapore counterparty in this pairing the real negotiation points are, if SIAC is chosen, locking in asset-preservation support in Vietnam and budgeting for the recognition step. Have counsel in Singapore review the foreign-law details before finalising for a specific deal.
