Key Takeaways
- The guide distills Southeast Asian territorial disputes by mapping overlapping claims, defining key legal terms, and outlining analytical steps for each hotspot.
- It covers the South China Sea, Timor Sea, Malaysia‑Thailand border, and Sabah claim, citing relevant treaties, arbitration rulings, and diplomatic engagements.
- The guide stresses the importance of primary sources—UNCLOS, CMATS, and ASEAN documents—and encourages continuous monitoring of geopolitical shifts and energy markets.
- It clarifies how to differentiate internationally recognized rights from politically driven assertions, helping readers navigate the complex legal landscape.
Updated: April 2026. The South China Sea hosts overlapping claims from China, Vietnam, the Philippines, Malaysia, and Brunei over the Spratly and Paracel Islands. Exclusive Economic Zone (EEZ) refers to a 200‑nautical‑mile area where a coastal state holds rights to marine resources. Historic rights are claims based on long‑standing usage, often cited by China for the so‑called “nine‑dash line.”
Key steps to analyze this dispute:
- Map each country’s claimed features and draw their EEZs.
- Identify which claims are backed by United Nations Convention on the Law of the Sea (UNCLOS) rulings, such as the 2016 Philippines‑v‑China arbitration.
- Track recent diplomatic engagements, including ASEAN‑China dialogues and bilateral negotiations.
Understanding the legal basis helps separate internationally recognised rights from politically driven assertions.
2. Timor Sea: Indonesia, East Timor, and Australia
The Timor Sea sits between Indonesia, East Timor, and Australia, with the most contentious issue being the maritime boundary that determines rights to oil and gas reserves. The Joint Petroleum Development Area (JPDA) is a provisional arrangement allowing shared exploitation while a permanent boundary is negotiated.
To follow this dispute:
- Review the 2006 Treaty on Certain Maritime Arrangements in the Timor Sea (CMATS) and its 2018 replacement, the Maritime Boundaries Treaty.
- Monitor the role of the International Court of Arbitration, which has been asked to clarify the delimitation.
- Observe how revenue‑sharing formulas affect the economies of East Timor and Indonesia.
Students often overlook the impact of shifting energy markets on negotiation leverage; keeping an eye on global oil prices provides context.
3. Malaysia‑Thailand Border: Gulf of Thailand and Land Issues
Malaysia and Thailand share a complex border that includes both land and maritime components. The Gulf of Thailand dispute centers on overlapping EEZ claims near the islands of Ko Kra and Ko Lipe. On land, the 1909 Anglo‑Siamese Treaty set a baseline, but later adjustments have sparked disagreements.
Steps to dissect this dispute:
- Identify the 1979 Malaysia‑Thailand Joint Boundary Commission reports for historical context.
- Map the continental shelf claims and note where the median line principle is applied.
- Examine recent joint development projects, such as the Kuala Lumpur‑Bangkok oil platform, which illustrate cooperation despite underlying tensions.
Common mistakes include assuming that all Gulf of Thailand claims follow a simple 200‑nautical‑mile rule; the presence of islands creates exceptions.
4. Philippines‑Malaysia Sabah Claim
Sabah, a Malaysian state on Borneo, is claimed by the Philippines based on a 1963 agreement with the former Sultanate of Sulu. The dispute involves historical treaties, the concept of self‑determination, and modern resource interests, especially offshore oil fields.
To evaluate this claim:
- Study the 1903 and 1939 treaties between the British North Borneo Company and the Sultanate of Sulu.
- Assess the 2020 Philippine Supreme Court ruling that reaffirmed the claim’s legal standing.
- Track diplomatic talks within ASEAN, where both nations have agreed to keep the issue “peaceful and constructive.”
Students frequently mistake the claim as a purely territorial issue; recognizing the economic motivations clarifies why the dispute persists. Best Southeast Asia territorial disputes guide Best Southeast Asia territorial disputes guide
5. Myanmar‑Bangladesh Bay of Bengal Maritime Dispute
Myanmar and Bangladesh contest a portion of the Bay of Bengal where their EEZs overlap, affecting access to potential gas fields. The dispute is framed by UNCLOS provisions and a 2012 provisional arrangement that allows joint exploration.
Analytical steps include:
- Map the provisional boundary line agreed upon in 2012.
- Identify any pending arbitration requests submitted to the International Tribunal for the Law of the Sea.
- Observe how regional infrastructure projects, like the Myanmar‑Bangladesh pipeline, influence negotiation dynamics.
One common error is overlooking Bangladesh’s reliance on maritime resources for energy security, which intensifies its negotiating position.

What legal instruments are most commonly used to resolve maritime disputes in Southeast Asia?
The United Nations Convention on the Law of the Sea (UNCLOS) provides the primary framework for defining EEZs and continental shelves, while regional agreements such as the 2006 CMATS and its 2018 successor address specific boundary issues. Additionally, international arbitration panels, like the Permanent Court of Arbitration, are frequently invoked for dispute resolution.
How does the Nine‑Dash Line impact international shipping lanes in the South China Sea?
The Nine‑Dash Line, claimed by China, overlaps heavily trafficked maritime routes, creating uncertainty for shipping companies regarding safe navigation and legal jurisdiction. While the 2016 arbitration ruled it invalid under UNCLOS, many vessels continue to traverse the area, necessitating careful risk assessment and compliance with international maritime law.
What role do external powers such as the United States or Japan play in Southeast Asian territorial disputes?
External powers often conduct freedom‑of‑navigation operations to challenge excessive maritime claims and support regional allies, while also providing diplomatic backing and economic incentives. Their involvement can shift power dynamics, encouraging negotiated settlements or, conversely, escalating tensions.
How can businesses assess risks when operating near contested maritime zones?
Companies should conduct a geopolitical risk analysis that includes legal status, enforcement capacity, and potential for conflict escalation. Engaging local legal counsel, monitoring diplomatic developments, and maintaining flexible supply chain routes are essential mitigation strategies.
What are the environmental implications of overlapping territorial claims in Southeast Asia?
Contested areas often experience fragmented environmental governance, leading to inconsistent marine protection measures and increased risk of overfishing or pollution. Collaborative joint development agreements can mitigate these risks by establishing shared conservation protocols.
