Maritime Disputes are disagreements between two or more countries over the ownership, control, or use of seas, oceans, islands, and coastal regions. These disputes are becoming more important because oceans are rich in natural resources such as fish, oil, natural gas, and minerals. Oceans also carry around 90% of the world’s trade through ships, making sea routes essential for the global economy.

For India, maritime disputes are important because the country has a coastline of more than 7,500 km and depends heavily on sea routes for trade, energy imports, and national security. The Indian Ocean Region (IOR) is one of the busiest maritime regions in the world, making peaceful management of maritime disputes necessary for regional stability.

What are Maritime Disputes?

Maritime disputes are conflicts between countries over rights and control in oceans, seas, coastal waters, islands, or underwater resources.

These disputes usually involve:

Maritime boundaries
Exclusive Economic Zones (EEZ)
Fishing rights
Oil and natural gas exploration
Shipping routes
Ownership of islands
Continental shelf claims
Military presence in strategic waters

Most maritime disputes are resolved through negotiations, international courts, arbitration, or agreements. However, some continue for decades because of political and strategic interests.

Why are Oceans Important?

About 71% of the Earth’s surface is covered by oceans. Traditionally, the world recognized four oceans:

Pacific Ocean
Atlantic Ocean
Indian Ocean
Arctic Ocean

Today, many countries also recognize the Southern Ocean surrounding Antarctica as the fifth ocean.

Oceans are important because they:

Support international trade
Provide food through fisheries
Contain valuable oil and gas reserves
Regulate the global climate
Support marine biodiversity
Connect countries through shipping routes

Because of these benefits, many countries compete for control over maritime regions.

Main Causes of Maritime Disputes

1. Maritime Boundary Disagreements

Countries often disagree about where their sea boundaries should be drawn.

2. Exclusive Economic Zones (EEZ)

Under international law, coastal countries enjoy special rights over resources within 200 nautical miles of their coast. When EEZs overlap, disputes arise.

3. Fishing Rights

Fishing is an important source of income for millions of people. Competition over fishing areas often creates conflicts.

4. Oil and Natural Gas

Many disputed seas contain huge reserves of petroleum and natural gas, making ownership highly valuable.

5. Strategic Importance

Certain sea routes are important for global trade and military movement. Countries try to increase their influence in these regions.

6. Historical Claims

Some countries claim islands or sea areas based on historical ownership, while others rely on modern international law.

Maritime Disputes Involving India

India-Bangladesh Maritime Dispute

India and Bangladesh had a long-standing dispute over their maritime boundary in the Bay of Bengal.

Bangladesh approached the United Nations Convention on the Law of the Sea (UNCLOS) for arbitration in 2009.

In 2014, the Permanent Court of Arbitration delivered its judgment.

The ruling:

Clearly defined the maritime boundary.
Settled territorial sea and EEZ limits.
Gave Bangladesh rights over a significant portion of the disputed area.
Reduced future tensions between both countries.

This is considered a successful example of peaceful dispute resolution through international law.

India-Sri Lanka Maritime Dispute

India and Sri Lanka share maritime boundaries in the Palk Strait and Palk Bay.

Katchatheevu Island

One of the biggest issues is Katchatheevu, a small island located in the Palk Strait.

India transferred the island to Sri Lanka through agreements signed in 1974 and 1976.

However, Indian fishermen continue to face problems because many traditionally fish near the island and sometimes cross into Sri Lankan waters.

This leads to:

Arrest of fishermen
Seizure of fishing boats
Diplomatic tensions

Both countries continue discussions to find practical solutions while respecting each other’s sovereignty.

Sethusamudram Ship Channel Project

This proposed shipping channel aims to connect India’s eastern and western coasts without ships having to travel around Sri Lanka.

The project promises economic benefits but has faced delays due to environmental, religious, security, and legal concerns.

India-China Maritime Competition

Although India and China do not have a direct maritime boundary dispute similar to land border issues, they compete strongly in the Indian Ocean Region.

China has expanded its presence by:

Investing in ports
Increasing naval deployments
Supporting anti-piracy missions
Building strategic partnerships with India’s neighboring countries

India has responded by:

Strengthening the Indian Navy
Increasing cooperation with Indian Ocean countries
Promoting freedom of navigation
Expanding naval exercises
Supporting regional security under its Act East Policy

Major Maritime Disputes Around the World

South China Sea Dispute

The South China Sea is one of the world’s most disputed maritime regions.

Countries involved include:

China
Vietnam
Philippines
Malaysia

United Kingdom-Spain

Both countries dispute sovereignty over Gibraltar and its surrounding territorial waters.

The disagreement affects shipping, fishing, and border management.

Canada-Denmark

Canada and Denmark disputed ownership of Hans Island for decades.

The dispute became famous as the “Whisky War” because both countries peacefully exchanged flags and bottles of alcohol.

In 2022, both nations officially settled the dispute through agreement.

United Kingdom-Argentina

The Falkland Islands (Islas Malvinas) remain disputed between the UK and Argentina.

The issue became internationally known after the Falklands War in 1982.

Although Britain currently controls the islands, Argentina continues to claim sovereignty.

International Laws for Maritime Disputes

United Nations Convention on the Law of the Sea (UNCLOS)

UNCLOS is often called the “Constitution of the Oceans.”

It provides legal rules governing maritime activities worldwide.

It defines important maritime zones such as:

Internal Waters
Territorial Sea
Contiguous Zone
Exclusive Economic Zone (EEZ)
Continental Shelf
High Seas

UNCLOS also explains:

Rights of coastal states
Navigation rights
Marine environmental protection
Resource management
Dispute settlement mechanisms

Most countries use UNCLOS as the legal basis for resolving maritime conflicts peacefully.

India’s Maritime Security Framework

India follows a three-layer maritime security system.

Indian Navy

The Navy protects India’s maritime interests, conducts naval operations, and patrols international maritime boundaries.

Indian Coast Guard

The Coast Guard protects India’s Exclusive Economic Zone, prevents smuggling, conducts search and rescue operations, and safeguards coastal security.

State Marine Police

The Marine Police patrol shallow coastal waters and work closely with local communities.

Together, these agencies create a strong coastal security system.
