Distinguishing disputes involving foreign elements from international disputes: a Comprehensive legal analysis

In cross-border commerce and international investment, the terms "dispute involving foreign element" and "international dispute" are frequently used interchangeably — often incorrectly. 

Although these two concepts share overlapping characteristics, they originate from different legal traditions, serve distinct purposes, and produce materially different consequences in terms of jurisdiction, applicable law, and the recognition and enforcement of judgments and arbitral awards. This article provides an in-depth comparative analysis of the two concepts and examines their practical significance for businesses, legal practitioners, and arbitration users.

1.What Is a Dispute involving Foreign Element?

1.1. Definition and Conceptual Framework

A dispute involving foreign element is a concept rooted in domestic law, particularly within the framework of private international law. It refers to a civil or commercial dispute in which at least one constituent element — whether a party, a juridical fact, or the subject matter — is connected to a foreign jurisdiction.

This concept is employed by national legal systems to determine when a domestic court or tribunal must apply special procedural rules and choice-of-law mechanisms rather than purely domestic substantive and procedural norms.

1.2. Legal Basis Under Vietnamese Law

Under Article 464(2) of the 2015 Code of Civil Procedure of Vietnam, a civil matter is deemed to involve a foreign element if it falls within any of the following categories:

a) At least one of the parties is a foreign individual, agency, or organization;

b) All parties are Vietnamese citizens, agencies, or organizations, but the establishment, modification, performance, or termination of the legal relationship in question occurred in a foreign country;

c) All parties are Vietnamese citizens, agencies, or organizations, but the subject matter (object) of the civil relationship is situated abroad.

Similarly, Article 3(4) of the 2010 Law on Commercial Arbitration of Vietnam provides a corresponding definition applicable in the context of commercial arbitration:

“Dispute involving foreign elements means a dispute arising in commercial relationships or other legal relationships involving foreign elements as defined in the Civil Code.”

1.3. Identifying Features

The identification of a foreign element rests on three principal indicators as below. The presence of any single indicator is sufficient to qualify the dispute as one involving a foreign element under Vietnamese law. The three criteria are alternative, not cumulative.

Indicator	Description	Illustrative Example
Parties (Ratione Personae)	At least one party is a foreign natural person, legal entity, or organization, or a Vietnamese national permanently residing abroad	Company A (Vietnam) enters into a sale contract with Company B (Singapore)
Juridical Facts (Ratione Facti)	The establishment, modification, or termination of the legal relationship takes place in a foreign jurisdiction	Two Vietnamese companies execute a contract in Tokyo, Japan
Subject Matter (Ratione Materiae)	The property or object of the legal relationship is located abroad	Two Vietnamese enterprises dispute ownership of real property situated in the United States

 

2. What Is an International Dispute?

2.1. Definition and Scope

An international dispute is a broader concept used across multiple branches of international law, including public international law, international commercial law, and international investment law. It encompasses not only disputes between private parties with cross-border dimensions, but also disputes between sovereign states, international organizations, and disputes between foreign investors and host states.

In the specific context of international commerce and arbitration, an international dispute typically refers to a dispute arising from a cross-border commercial transaction in which the parties maintain their places of business in different countries, or in which the performance of the contract or the subject matter of the dispute bears a significant connection to more than one jurisdiction.

2.2. Classification of International Disputes

International disputes can be broadly categorized into three principal types:

a) State-to-State disputes

These disputes fall within the domain of public international law and are resolved through mechanisms such as:

• The International Court of Justice (ICJ)
• The Dispute Settlement Body (DSB) of the World Trade Organization
• The International Tribunal for the Law of the Sea (ITLOS)
• Ad hoc arbitral tribunals constituted under international treaties

b) Investor-State disputes

These disputes arise between a foreign investor and the government of the host state, typically concerning alleged breaches of investment protection obligations. Common resolution mechanisms include:

• Arbitration under the ICSID Convention (Washington Convention, 1965)
• Arbitration under the UNCITRAL Arbitration Rules
• Arbitration under the UNCITRAL Arbitration Rules

c) International commercial disputes

These disputes arise between private commercial parties (typically corporations or traders) with places of business in different states. They may concern international sale of goods, cross-border services, international transportation, marine insurance, intellectual property licensing, joint ventures, and a wide array of other commercial relationships.

2.3. Criteria for Determining "Internationality"

The UNCITRAL Model Law on International Commercial Arbitration (as amended in 2006) provides a widely adopted framework for determining when an arbitration — and by extension, the underlying dispute — is international in character.

Under Article 1(3) of the Model Law, an arbitration is international if:

a) the parties to an arbitration agreement have, at the time of the conclusion of that agreement, their places of business in different States; or
b) one of the following places is situated outside the State in which the parties have their places of business:
(i) the place of arbitration if determined in, or pursuant to, the arbitration agreement;
(ii) any place where a substantial part of the obligations of the commercial relationship is to be performed or the place with which the subject-matter of the dispute is most closely connected; or
c) the parties have expressly agreed that the subject-matter of the arbitration agreement relates to more than one country.

3. Key Differences Between the Two Concepts

3.1. In-Depth Analysis of Core Distinctions

a) Origin and Legal Nature

The concept of a dispute involving foreign element is a creature of domestic legislation. Each national legal system defines the concept according to its own legislative policy and judicial tradition. It serves an essentially inward-looking function: it tells a domestic court or authority when a case is not purely domestic, thereby triggering a distinct set of procedural and substantive rules designed for cross-border situations.

The concept of an international dispute, by contrast, is fundamentally outward-looking. It derives its meaning from international conventions, multilateral treaties, and institutional rules that transcend any single national legal system. Its purpose is to establish a common, internationally recognized framework for resolving disputes that engage the interests, laws, and enforcement mechanisms of multiple states.

b) The Relationship Between the Two Concepts

The two concepts overlap but are not coextensive. The relationship between them can be summarized as follows:

• Overlap: A dispute involving foreign element under domestic law may simultaneously qualify as an international dispute. Example: A Vietnamese exporter sues a Korean importer for non-payment under a cross-border sale of goods contract. This dispute is both a "dispute involving foreign element" under Vietnamese law (due to the foreign party) and an "international dispute" under the UNCITRAL Model Law (places of business in different states).
• International dispute without a foreign element (under domestic law): A dispute between two sovereign states over maritime boundaries is undoubtedly an international dispute but falls entirely outside the scope of "civil matters involving a foreign element" as defined by domestic civil procedure legislation. Example: The Philippines v. China arbitration regarding the South China Sea (PCA Case No. 2013-19).
• Foreign element without internationality (under international standards): Two Vietnamese companies, both headquartered in Vietnam, may enter into a contract in a foreign country. Under Vietnamese procedural law, this dispute involves a foreign element (the juridical fact occurred abroad). However, under the UNCITRAL Model Law, this dispute would likely not be classified as international, since both parties have their places of business in the same state. This discrepancy has practical implications for the applicability of international arbitration rules and enforcement conventions.

3.2. Comparative Overview

Criterion	Dispute Involving Foreign Element	International Dispute
Legal origin	National (domestic) law — varies by jurisdiction	International legal instruments, treaties, transnational arbitration rules, and customary international law
Scope of application	Applied within a single national legal system to trigger special procedural and choice-of-law rules	Applied across multiple jurisdictions; operates on a transnational or global level
Parties	Private parties only (natural persons, legal entities, organizations)	Private parties, sovereign states, state entities, international organizations
Identification criteria	Based on domestic statutory indicators (e.g., nationality/domicile of parties, locus of juridical facts, situs of subject matter)	Based on place of business, seat of arbitration, place of performance, or party agreement (per UNCITRAL Model Law and institutional arbitration rules)
Purpose of classification	Determine domestic court/tribunal jurisdiction and applicable choice-of-law rules	Determine the international character of the dispute for purposes of applying international procedural rules, treaty obligations, and enforcement conventions
Resolution mechanisms	Domestic courts, domestic or foreign arbitral tribunals	International arbitral institutions, international courts and tribunals, inter-state dispute resolution bodies
Applicable law determination	National choice-of-law rules (e.g., Part Five of the Vietnamese Civil Code 2015)	Party autonomy; institutional arbitration rules; international conflict-of-laws principles; transnational legal norms (lex mercatoria)

4. Conclusion

The distinction between a dispute involving foreign element and an international dispute is far more than a matter of academic taxonomy. It has direct, tangible consequences for the determination of jurisdiction, the selection of applicable law, the conduct of proceedings, and the enforceability of the resulting judgment or arbitral award across borders. For businesses engaged in cross-border transactions, in-house counsel, and legal practitioners advising on international matters, a clear understanding of this distinction enables:

✅ Informed drafting of dispute resolution clauses that accurately reflect the nature and anticipated forum of potential disputes.

✅ Strategic selection of arbitral seats, institutional rules, and governing law provisions that maximize enforceability and procedural efficiency.

✅ Proper assessment of jurisdictional risks, including the possibility of parallel proceedings and conflicting decisions in multiple fora.

✅ Effective enforcement planning, ensuring that awards and judgments can be recognized and executed in the jurisdictions where the opposing party's assets are located.
