What is UNCLOS?
Historical Background
Key Points
13 points- 1.
The concept of Territorial Waters extends a nation's sovereignty 12 nautical miles (approximately 22 kilometers) from its coastline. Within this zone, the coastal state has complete control, just like it does on land. This includes the right to regulate passage, fishing, and resource exploitation. For example, India has full control over the waters surrounding the Andaman and Nicobar Islands within this limit.
- 2.
The Exclusive Economic Zone (EEZ) extends 200 nautical miles (approximately 370 kilometers) from a nation's coastline. Within its EEZ, a coastal state has sovereign rights for the purpose of exploring and exploiting, conserving and managing the natural resources, whether living or non-living, of the waters superjacent to the seabed and of the seabed and its subsoil. India, for example, has the exclusive right to explore for oil and gas in its EEZ off the coast of Mumbai.
- 3.
Innocent Passage allows ships of all states, whether coastal or land-locked, to pass through the territorial sea of another state, provided the passage is continuous and expeditious and is not prejudicial to the peace, good order or security of the coastal state. A Chinese cargo ship can sail through India's territorial waters as long as it is simply passing through and not engaging in activities like spying or fishing.
- 4.
Contiguous Zone extends 24 nautical miles from the baseline from which the breadth of the territorial sea is measured. Within this zone, a coastal state can enforce laws related to customs, fiscal, immigration, and sanitation. This allows India to prevent smuggling or illegal immigration just beyond its territorial waters.
- 5.
The Continental Shelf extends beyond the territorial sea to the outer edge of the continental margin, or to a distance of 200 nautical miles where the outer edge of the continental margin does not extend up to that distance. Coastal states have sovereign rights over the continental shelf for the purpose of exploring it and exploiting its natural resources. India can explore and exploit minerals on its continental shelf, even if it extends beyond its EEZ under certain conditions.
- 6.
Deep Seabed Mining is regulated by the International Seabed Authority (ISA), an organization established by UNCLOS. The ISA grants licenses for exploration and exploitation of mineral resources in the seabed beyond national jurisdiction. This ensures that the benefits of deep seabed mining are shared equitably among all nations.
- 7.
Marine Scientific Research is generally allowed, but coastal states have the right to regulate research activities within their territorial sea and EEZ. Foreign researchers need to obtain permission from the coastal state before conducting research. This is to ensure that research activities do not harm the marine environment or threaten the security of the coastal state.
- 8.
Dispute Resolution is a key aspect of UNCLOS. The convention provides for various mechanisms for settling disputes, including the International Tribunal for the Law of the Sea (ITLOS), the International Court of Justice (ICJ), and arbitration. This helps prevent conflicts from escalating and ensures that disputes are resolved peacefully and in accordance with international law.
- 9.
The concept of Archipelagic Waters applies to archipelagic states like Indonesia and the Philippines. It allows these states to draw closing lines connecting the outermost points of the outermost islands and reefs, enclosing the waters within as archipelagic waters. Within these waters, the archipelagic state has sovereignty, subject to certain rights of passage for foreign vessels.
- 10.
One exception to the EEZ rule is that landlocked countries have the right to access the sea for transportation and trade. UNCLOS requires coastal states to allow landlocked countries access to and from the sea, without discrimination. Nepal, being a landlocked country, relies on India for access to the sea through Kolkata port.
- 11.
A practical implication of UNCLOS is that it affects how countries manage their fisheries. UNCLOS sets out rules for the conservation and management of living resources in the EEZ, requiring coastal states to ensure that these resources are not overexploited. This impacts the livelihoods of fishermen and the availability of seafood for consumers.
- 12.
UNCLOS also addresses the issue of maritime boundaries between states with opposite or adjacent coasts. It provides that the delimitation of the territorial sea, EEZ, and continental shelf between such states shall be effected by agreement on the basis of international law, as referred to in Article 38 of the Statute of the International Court of Justice, in order to achieve an equitable solution. The dispute between India and Bangladesh over their maritime boundary in the Bay of Bengal was resolved through arbitration under UNCLOS.
- 13.
UPSC specifically tests your understanding of the different maritime zones and the rights and obligations of states within those zones. You should be able to differentiate between territorial waters, EEZ, and the high seas, and understand the implications of these zones for resource management, security, and international relations.

Recent Developments
10 developmentsIn 2016, the Permanent Court of Arbitration issued a ruling in the South China Sea arbitration case brought by the Philippines against China, finding that China's claims of historic rights within the "nine-dash line" were inconsistent with UNCLOS. China rejected the ruling.
In 2021, the International Tribunal for the Law of the Sea (ITLOS) delivered a judgment in the case concerning the delimitation of the maritime boundary between Mauritius and Maldives in the Indian Ocean, highlighting the importance of equitable principles in maritime boundary delimitation.
In 2022, several countries expressed concerns about illegal, unreported, and unregulated (IUU) fishing activities in various parts of the world, emphasizing the need for stronger enforcement of UNCLOS provisions related to fisheries management.
In 2023, discussions continued at the International Seabed Authority (ISA) regarding the development of regulations for deep seabed mining, with debates focusing on environmental protection and the equitable sharing of benefits.
Currently, the implementation of UNCLOS is facing challenges due to geopolitical tensions and conflicting interpretations of its provisions. The ongoing disputes in the South China Sea and the increasing presence of naval forces in the Indian Ocean highlight the need for greater cooperation and adherence to international law.
The Arctic Council is increasingly relevant to UNCLOS as climate change opens up new shipping routes and resource extraction opportunities in the Arctic, raising questions about sovereignty and maritime boundaries.
The European Union has been actively promoting the implementation of UNCLOS through its maritime security strategy and its efforts to combat illegal fishing and protect marine biodiversity.
Several countries, including the United States, have not ratified UNCLOS, although they generally recognize it as customary international law. This creates complexities in international relations and maritime governance.
India has been actively participating in discussions and initiatives related to maritime security and cooperation in the Indian Ocean region, emphasizing the importance of UNCLOS in maintaining peace and stability.
The future of UNCLOS depends on the willingness of states to uphold its principles and resolve disputes peacefully. The increasing challenges posed by climate change, resource scarcity, and geopolitical competition require a renewed commitment to international cooperation and the rule of law.

1 topicsFrequently Asked Questions
121. What's the most common MCQ trap regarding the breadth of maritime zones under UNCLOS?
Students often confuse the distances of the Territorial Sea, Contiguous Zone, and Exclusive Economic Zone (EEZ). The correct distances are 12 nautical miles, 24 nautical miles, and 200 nautical miles respectively. Examiners often mix these up to test factual recall.
Exam Tip
Remember the sequence: 12, then double it for the Contiguous Zone (24), then a big jump to 200 for the EEZ.
2. Why do students often confuse 'Innocent Passage' with 'Transit Passage,' and what's the key distinction?
Both relate to navigation through a coastal state's waters, but 'Innocent Passage' applies to the territorial sea, allowing passage that is not prejudicial to the peace, good order, or security of the coastal state. 'Transit Passage' applies to straits used for international navigation, allowing for greater freedom of navigation, including continuous and expeditious transit. Submarines, for example, can transit submerged in 'Transit Passage' but must be on the surface and show their flag in 'Innocent Passage'.
Exam Tip
Think of 'Transit' as 'Transportation' through international straits, allowing more freedom, while 'Innocent' is more restricted within territorial waters.
3. What is the role of the International Seabed Authority (ISA), and why is it currently facing criticism?
The ISA regulates deep seabed mining in areas beyond national jurisdiction, ensuring that benefits are shared equitably. It's facing criticism because of concerns about the environmental impact of deep seabed mining, the lack of transparency in its decision-making processes, and allegations of undue influence from corporations seeking mining licenses. The slow progress in finalizing regulations that adequately protect the marine environment is also a major concern.
4. How does UNCLOS address the issue of overlapping EEZ claims, and what real-world example illustrates this?
UNCLOS encourages states with overlapping EEZ claims to negotiate a resolution. If negotiations fail, Article 74 provides for delimitation by agreement on the basis of international law, as referred to in Article 38 of the Statute of the International Court of Justice. A real-world example is the ongoing dispute between Greece and Turkey in the Aegean Sea, where overlapping claims to EEZs and continental shelf have led to tensions and require continuous negotiation.
5. What are the limitations of UNCLOS in addressing modern maritime security challenges like piracy and terrorism?
While UNCLOS provides a framework for maritime zones and rights, it doesn't specifically address piracy and terrorism. Article 100 does mention that all states should cooperate to repress piracy. The convention focuses more on state-to-state relations and resource management. Enforcement against non-state actors often requires additional agreements and cooperation between nations, which can be slow and complex. For example, the Gulf of Aden remains a piracy hotspot despite UNCLOS.
6. In an MCQ, what's a common trick examiners use regarding dispute resolution mechanisms under UNCLOS?
Examiners often present a scenario and ask which dispute resolution mechanism is *mandatory* for a particular type of dispute. While UNCLOS provides options like ITLOS, ICJ, and arbitration, the choice of mechanism often depends on the parties' agreement. No single mechanism is universally mandatory for all disputes. Students often incorrectly assume ITLOS is always the default.
Exam Tip
Carefully read the scenario to see if the parties have already agreed on a specific dispute resolution method. If not, remember that multiple options exist.
7. Why does UNCLOS exist – what problem does it solve that no other mechanism could?
UNCLOS provides a comprehensive, universally agreed-upon framework for governing the oceans. Before UNCLOS, maritime law was fragmented, leading to disputes over resource exploitation, navigation rights, and maritime boundaries. UNCLOS establishes clear rules and procedures for these issues, reducing the potential for conflict and promoting cooperation among nations. It's the 'constitution for the oceans,' providing a single, overarching legal order.
8. What is the strongest argument critics make against UNCLOS, and how would you respond?
Critics argue that UNCLOS is ineffective in addressing the actions of powerful states that disregard its provisions, particularly in areas like the South China Sea. They point to China's rejection of the 2016 Permanent Court of Arbitration ruling as evidence of this weakness. In response, one could argue that while UNCLOS isn't perfect, it still provides a legal basis for challenging such actions and mobilizing international pressure. Without UNCLOS, there would be even less recourse against unilateral actions.
9. How should India reform or strengthen UNCLOS going forward?
India could advocate for several reforms: answerPoints: * Strengthening enforcement mechanisms: Push for more effective ways to ensure compliance with UNCLOS rulings, possibly through a UN body with enforcement powers. * Clarifying ambiguities: Work with other nations to clarify ambiguous provisions in UNCLOS, particularly those related to marine scientific research and deep seabed mining. * Promoting capacity building: Support initiatives to help developing nations build their capacity to monitor and protect their maritime zones. * Leading by example: Consistently adhere to UNCLOS principles in its own maritime activities and boundary disputes.
10. What happened when UNCLOS was last controversially applied or challenged?
The most significant recent challenge was China's rejection of the 2016 Permanent Court of Arbitration ruling on the South China Sea. The court found that China's
11. What is the one-line distinction between UNCLOS and the International Maritime Organization (IMO)?
UNCLOS is the 'constitution for the oceans,' setting out rights and responsibilities of states, while the IMO is a specialized agency focused on maritime safety and security and prevention of marine pollution from ships.
Exam Tip
Think of UNCLOS as the broad legal framework and the IMO as the technical agency for shipping.
12. If UNCLOS didn't exist, what would change for ordinary citizens?
Without UNCLOS, there would likely be increased international disputes over fishing rights, oil and gas exploration, and shipping lanes, potentially leading to higher prices for goods, disruptions in trade, and even armed conflicts. Coastal communities would be particularly vulnerable to exploitation of marine resources by foreign entities. The lack of clear environmental regulations could also lead to increased marine pollution and damage to ecosystems, impacting food security and livelihoods.
