India–Vietnam SAHYOG-HOPTAC Exercise 2026: Maritime Security and Indo-Pacific Significance
Why in News?
The Indian Coast Guard (ICG) and Vietnam Coast Guard (VCG) are scheduled to conduct the joint maritime exercise SAHYOG-HOPTAC at sea on 27 August 2026.
The exercise is aimed at improving:
- Operational coordination
- Interoperability
- Maritime Search and Rescue
- Maritime law enforcement
- Marine pollution response
- Exchange of professional best practices
The exercise follows the 7th India–Vietnam Coast Guard High-Level Meeting, held in Chennai on 25 August 2026 under the framework of the 2015 Memorandum of Understanding on Coast Guard Cooperation.
As of the morning of 27 August, the official government statement describes SAHYOG-HOPTAC as scheduled to be conducted today; therefore, any specific operational outcome should be added only after an official post-exercise release.
What is SAHYOG-HOPTAC?
SAHYOG-HOPTAC is a bilateral Coast Guard exercise involving India and Vietnam.
Unlike a conventional naval combat exercise, its primary focus is on maritime safety, law enforcement, humanitarian response and environmental protection.
The latest exercise seeks to improve the ability of both Coast Guards to work together during real-world maritime emergencies.

Interoperability
The larger objective is to create forces that can communicate, coordinate and respond effectively during incidents at sea.
Background: India–Vietnam Coast Guard Cooperation
India and Vietnam signed a Memorandum of Understanding on Coast Guard Cooperation in 2015.
The agreement established cooperation in areas including:
- Maritime safety
- Search and rescue
- Prevention of transnational maritime crimes
- Piracy and armed robbery
- Smuggling
- Illegal trafficking
- Illegal migration
- Exchange of information
- Marine pollution
- Training and professional exchanges
The MoU also provides for rapid communication and exchange of operational information between the two Coast Guards.
This is important because modern maritime security is not limited to military threats.
Countries must also deal with:
Piracy + Smuggling + Illegal fishing + Trafficking + Pollution + Natural disasters + Maritime accidents
7th India–Vietnam Coast Guard High-Level Meeting
The 7th High-Level Meeting between the Indian Coast Guard and Vietnam Coast Guard was held in Chennai on 25 August 2026.
It was co-chaired by:
- Director General Paramesh Sivamani, Indian Coast Guard
- Major General Luong Dinh Hung, Vice Commandant, Vietnam Coast Guard
The meeting reviewed existing bilateral cooperation and discussed ways to expand:
- Training programmes
- Professional exchanges
- Ship visits
- Maritime Search and Rescue
- Maritime law enforcement
- Marine pollution response
- Capacity building
Both sides emphasised greater operational coordination and interoperability.
What Does “Interoperability” Mean?
Interoperability means the ability of forces from different countries to operate together effectively.
This requires compatibility in:
- Communication
- Procedures
- Training
- Command coordination
- Emergency-response protocols
For example, if a ship catches fire or an oil spill occurs in international waters, multiple agencies may need to respond.
Exercises such as SAHYOG-HOPTAC help ensure that different Coast Guards can cooperate without confusion.
Why Maritime Search and Rescue Matters
Search and Rescue (SAR) refers to locating and helping people or vessels in distress at sea.
It can involve:
- Ship accidents
- Cyclones
- Fire onboard vessels
- Missing fishing boats
- Medical emergencies
- Aircraft accidents over the sea
The Indian Ocean and surrounding seas carry some of the world's busiest shipping routes.
Effective SAR cooperation can therefore save both lives and economic assets.
Maritime Law Enforcement
Coast Guards are particularly important in enforcing national and international maritime laws.
Major challenges include:
Piracy
Attacks on vessels for robbery or hostage-taking.
Smuggling
Illegal movement of:
- Drugs
- Weapons
- Contraband
- People
Illegal, Unreported and Unregulated Fishing
IUU fishing damages fish stocks and affects coastal livelihoods.
Maritime trafficking
Criminal networks can use sea routes for people or narcotics trafficking.
Cooperation between Coast Guards enables faster exchange of information about suspicious vessels and criminal activities.
Marine Pollution Response
Marine pollution is another major component of Coast Guard cooperation.
Oil spills and hazardous substances can damage:
- Fisheries
- Mangroves
- Coral reefs
- Coastal communities
- Marine biodiversity
Oil spills also spread across maritime boundaries.
Therefore, one country's response capacity may not always be sufficient.
Joint exercises help forces practise:
- Containment
- Recovery
- Coordination
- Environmental response
This makes Coast Guard cooperation both a security and environmental issue.
Coast Guard vs Navy: Important for Prelims
Students often confuse the functions of a Coast Guard with those of a Navy.
| Coast Guard | Navy |
|---|---|
| Maritime law enforcement | Military defence |
| Search and rescue | Naval warfare |
| Anti-smuggling operations | Strategic deterrence |
| Pollution response | Sea control |
| Coastal security | Combat operations |
| Fisheries protection | Power projection |
There can be overlap during national emergencies, but their principal roles are different.
Easy way to remember
Navy → Defence against military threats
Coast Guard → Maritime safety, security and law enforcement
India–Vietnam Strategic Relationship
India and Vietnam share long-standing political, cultural and strategic relations.
Their relationship was elevated to a Comprehensive Strategic Partnership in 2016.
A May 2026 joint statement further reflected the growing depth of the bilateral strategic partnership.
Vietnam is also an important pillar of India's Act East Policy.
Areas of cooperation include:
- Defence
- Maritime security
- Trade
- Energy
- Digital technologies
- Space
- Capacity building
- Education
- Culture
Why Vietnam Matters to India
Vietnam occupies an important strategic location in Southeast Asia.
It is situated close to major maritime routes connecting:
Indian Ocean → Strait of Malacca → South China Sea → Western Pacific
Vietnam therefore matters to India's:
- Act East Policy
- Indo-Pacific strategy
- Maritime trade
- ASEAN engagement
- Supply-chain diversification
India has historically described Vietnam as an important pillar of its Act East Policy.
Connection with India's Act East Policy
India's Act East Policy seeks deeper engagement with Southeast and East Asia.
It includes:
- Economic integration
- Connectivity
- Security cooperation
- Defence partnerships
- People-to-people ties
Vietnam has become one of India's important partners under this policy.
SAHYOG-HOPTAC represents the maritime-security dimension of Act East.

Regional Safety and Security
Indo-Pacific Significance
The Indo-Pacific is home to some of the world's most important:
- Shipping lanes
- Energy routes
- Ports
- Fisheries
- Global supply chains
India supports an Indo-Pacific that is:
- Open
- Inclusive
- Stable
- Governed by international law
- Supportive of freedom of navigation
Vietnam is also a major maritime state in Southeast Asia.
Therefore, practical cooperation between the two countries strengthens regional maritime capacity without requiring every form of cooperation to be military in nature.
South China Sea Context
Vietnam is one of the states directly involved in territorial and maritime disputes in the South China Sea.
India is not a claimant state in these disputes.
However, India has important interests in:
- Freedom of navigation
- International law
- Maritime trade
- Energy security
- Stable sea lanes
This is why developments in the South China Sea matter to India even when India is not directly involved in the territorial dispute.
Important UPSC distinction
India supports freedom of navigation and peaceful resolution of disputes, but India is not a claimant in the South China Sea territorial disputes.
Role of UNCLOS
The United Nations Convention on the Law of the Sea (UNCLOS) provides the principal international legal framework governing the oceans.
It deals with areas such as:
- Territorial Sea
- Exclusive Economic Zone
- Continental Shelf
- Navigation
- Marine resources
- Maritime jurisdiction
Rules-based maritime behaviour is particularly important in crowded and disputed maritime regions.
Prelims Fact
Under UNCLOS, the Exclusive Economic Zone (EEZ) generally extends up to:
200 nautical miles
from the relevant coastal baseline, subject to applicable legal provisions.
India's Wider Maritime Vision
India's regional maritime approach has historically been linked with the concept of SAGAR — Security and Growth for All in the Region.
India has used maritime cooperation to strengthen:
- Search and rescue
- Humanitarian assistance
- Disaster relief
- Anti-piracy operations
- Capacity building
- Maritime domain awareness
India's maritime policy has also sought to connect South Asia with Southeast Asia through its Act East approach.
Why Coast Guard Diplomacy Matters
Defence diplomacy is often associated with naval ships and military exercises.
But Coast Guard cooperation offers another important layer.
It allows countries to work together on less politically sensitive but highly practical issues such as:
- Fishing
- Safety
- Pollution
- Smuggling
- Rescue operations
This builds trust gradually.
Therefore:
Operational cooperation
↓
Professional trust
↓
Institutional confidence
↓
Stronger strategic partnership
This is sometimes described as a form of maritime confidence-building.
Importance for India's Maritime Security
1. Safer Sea Lanes
India's economy depends heavily on maritime trade.
Cooperation with Southeast Asian maritime agencies strengthens the safety of important routes.
2. Countering Transnational Crime
Criminal networks operate across borders.
No single Coast Guard can effectively tackle them alone.
3. Disaster Response
Cyclones, accidents and pollution incidents require rapid multinational coordination.
4. Stronger Act East Policy
Operational maritime cooperation makes India's engagement with ASEAN states more practical and visible.
5. Capacity Building
Joint exercises allow both sides to exchange operational experience and best practices.
Challenges
Despite growing cooperation, several wider challenges remain.
Maritime Territorial Disputes
The South China Sea remains one of Asia's most sensitive geopolitical regions.
Major-Power Competition
Strategic competition between China and the United States affects the regional security environment.
IUU Fishing
Illegal fishing continues to threaten marine resources and livelihoods across the Indo-Pacific.
Transnational Crime
Smuggling and trafficking networks increasingly use sophisticated methods.
Climate Risks
Rising sea levels, stronger storms and marine pollution create additional pressure on coastal states.
Way Forward
India and Vietnam can deepen maritime cooperation through:
More Joint Exercises
Regular exercises improve familiarity and readiness.
Maritime Domain Awareness
Greater exchange of information can help track suspicious vessels and maritime threats.
Search & Rescue Networks
Joint protocols can improve emergency response.
Pollution-Control Cooperation
Oil-spill and environmental-response capacity should be expanded.
Training and Capacity Building
Officers and personnel should participate in more exchange programmes.
Wider ASEAN Cooperation
India–Vietnam cooperation can complement India's broader maritime engagement with ASEAN.
Key Takeaway
The SAHYOG-HOPTAC exercise reflects the gradual expansion of India–Vietnam relations from political friendship into practical maritime-security cooperation.
Its importance lies not in conventional military combat but in building capacity to deal with real challenges such as:
Search & Rescue + Maritime Crime + Pollution + Coastal Security
For India, such cooperation strengthens the Act East Policy, improves maritime partnerships with ASEAN states and contributes to a safer Indo-Pacific.
