Officials from both nations review maritime trafficking trends, share intelligence and pledge stronger institutional coordination against illicit drugs in the Indian Ocean region.

Narcotics control agencies of India and Sri Lanka held their fifth Director General-level talks in Colombo on 23 September 2026, reinforcing bilateral efforts to combat illicit drug trafficking across the Indian Ocean.

The meeting builds directly on the renewed emphasis on security cooperation during Indian Prime Minister Narendra Modi’s state visit to Sri Lanka in April 2025. It gained added urgency after Sri Lankan President Anura Kumara Dissanayake sought India’s “fullest support” in tackling the regional drug menace during talks with Indian Defence Minister Rajnath Singh in Colombo on 9 September 2026.

High-Level Delegations Review Emerging Threats

The Indian side was led by R. Sudhakar, Deputy Director General of the Narcotics Control Bureau (NCB). The Sri Lankan delegation was headed by K.D.G.L. Ashoka Dharmasena, Deputy Inspector General of the Police Narcotics Bureau (PNB).

India’s team included officials from the Tamil Nadu Police, Indian Coast Guard and Ministry of External Affairs, alongside NCB personnel. Sri Lanka fielded representatives from the Attorney General’s Department, Sri Lanka Customs, Sri Lanka Coast Guard, Government Analyst’s Department, Special Task Force, Sri Lanka Navy, National Dangerous Drugs Control Board (NDDCB), Financial Intelligence Unit and other PNB officers.

Both sides examined emerging trends in drug trafficking, with particular focus on maritime routes. They discussed tracing organised criminal networks, coordinating operational intelligence and investigations into organised crime. Actionable intelligence on drug trafficking operatives, routes and mechanisms was shared during the talks.

Maritime Routes Remain Primary Concern

Maritime pathways through the Indian Ocean have become a critical vulnerability for both countries. Southern Sri Lankan waters and the Palk Strait corridor linking Tamil Nadu and Sri Lanka serve as key transit points for heroin, methamphetamine and other substances often originating from the Golden Crescent region.

Recent years have seen significant seizures. Sri Lankan authorities reported large hauls of heroin and crystal meth (“ice”), while Indian agencies, including the NCB, Coast Guard and Navy, have intercepted multi-hundred-kilogram consignments in joint operations. Routes from Nepal via India into Sri Lanka have also drawn renewed scrutiny for hashish oil and charas smuggling.

The proximity of Tamil Nadu makes state-level police involvement essential. Analysts note that a joint mechanism involving Tamil Nadu authorities, the central government and Sri Lankan agencies could improve real-time information sharing on trafficking networks, maritime surveillance and proceeds of crime.

Political Momentum Strengthens Cooperation

President Dissanayake’s recent appeal for Indian support followed the launch of Sri Lanka’s island-wide anti-drug programme. During Defence Minister Singh’s visit – the first by an Indian Defence Minister in nearly four decades – three defence-related MoUs were also signed, covering equipment upgrades, academic exchanges and cadet corps cooperation.

India has prioritised narcotics control as part of its broader regional security architecture. The NCB coordinates with multilateral forums including SAARC, BIMSTEC, the Colombo Security Conclave (CSC) and the United Nations Office on Drugs and Crime. In May 2026, the NCB hosted a CSC workshop in New Delhi on transnational drug smuggling by sea, attended by officers from Bangladesh, Maldives, Mauritius, Seychelles and Sri Lanka.

India has signed bilateral agreements or MoUs with more than 40 countries to curb drug trafficking and regularly holds DG-level talks with neighbours including Sri Lanka, Myanmar, Bangladesh and others.

Institutional Ties Set for Further Strengthening

At the conclusion of the Colombo meeting, both sides agreed to deepen institutional cooperation and coordination between their drug law-enforcement agencies. The focus remains on addressing evolving challenges posed by illicit narcotics trafficking, including synthetic drugs and precursor chemicals.

This aligns with India’s domestic push. In June 2026, Home Minister Amit Shah launched the Vision Document on Narcotics Control (2026-2029), aiming for measurable progress toward a drug-free India by 2047. The document prioritises enforcement, intelligence, precursor control, demand reduction and capacity building through the four-tier Narco-Coordination Centre (NCORD) mechanism.

For Sri Lanka, the talks support ongoing naval and coast guard efforts against drug trafficking and illegal fishing in its maritime domain. Partnerships with India have already facilitated intelligence-driven interdictions of dhows and trawlers carrying large narcotics consignments.

Regional Security Implications

The drug trade is increasingly linked to organised crime, money laundering and potential terror financing, elevating it beyond a pure law-enforcement issue. Profits from maritime smuggling fund broader criminal networks operating across South Asia and the Indian Ocean region.

Experts argue that effective responses require harmonised legal procedures, controlled delivery operations, and shared best practices on investigation and prosecution. Capacity-building workshops, joint patrols and real-time intelligence exchange between the Indian Coast Guard, Sri Lanka Navy and specialised narcotics bureaus form the operational backbone of current cooperation.

The fifth DG-level meeting signals continuity rather than a one-off event. Previous rounds have focused on heroin, psychotropic substances, precursors and transnational syndicates. Sustained dialogue helps both countries adapt to shifting routes and new synthetic threats.

Political Will

As the Indian Ocean remains a major transit zone, closer India-Sri Lanka coordination will be central to regional stability. The involvement of Tamil Nadu Police in the latest talks underscores the importance of sub-national engagement alongside national agencies.

Both governments have demonstrated political will. Continued sharing of actionable intelligence, joint operations and institutional mechanisms will determine how effectively the two neighbours can disrupt trafficking networks that threaten public health, security and economic stability on both sides of the Palk Strait.
