G7 launches 14-port network to hunt drug cargoes in containers

Fourteen of the world's largest container ports joined a new G7-backed enforcement network yesterday, betting that artificial intelligence and shared intelligence can spot narcotics hidden in legitimate cargo flows.

The G7+ Ports Network launched formally in Marseille, uniting the leading industrialised economies with Brazil and South Korea. Port authorities, customs organisations and law enforcement agencies are all connected through the initiative. The goal is blunt: identify suspicious container movements and break the maritime routes that organised crime currently uses with reasonable confidence.

Who is in, and who is watching?

The port roster includes Marseille, Le Havre, Dunkirk, Hamburg, Genoa, Busan and Houston. Around them sit four international bodies: Interpol, the International Maritime Organization, the World Customs Organization and the UN Office on Drugs and Crime.

That mix matters commercially. When customs bodies and port authorities share screening data across origin, transit and destination points, containers that once cleared one checkpoint cleanly now face scrutiny at every leg. Investigations, in theory, start following the box rather than stopping at the first jurisdiction.

What does this change for shippers and carriers?

French foreign minister Jean-Noël Barrot said the network will use tools including artificial intelligence to track suspicious shipments and improve information exchange between ports. In practice, that means more flagged boxes, more targeted inspections and a higher chance that a suspicious container gets held — somewhere.

The trade-off the initiative has to manage is familiar. Barrot noted that roughly 70% of illegal drugs entering France arrive through ports. Screening enough of those flows to matter, without slowing the enormous volume of legitimate containers, is the operational challenge. Ports that flag cargo faster will keep throughput; ports that inspect broadly will create dwell-time costs for carriers and forwarders.

The idea isn't new. Leaders first proposed the network at June's G7 summit in Évian, where they identified maritime transport as a principal route for international trafficking in narcotics and precursor chemicals. Marseille yesterday turned that communiqué language into an operating structure.

France has already been building toward this

The network sits on top of an active French enforcement push. France has signed more than 20 bilateral agreements targeting drug trafficking since late 2025. It has also increased specialist personnel deployed in Latin America and the Caribbean by more than 30%.

Put differently: Paris has spent months deepening its presence at the origin end of cocaine routes, and the port network now gives those efforts a coordinated destination-side counterpart. The stated intent is to coordinate investigations across origin, transit and destination ports — closing the gaps that traffickers currently exploit when cargo changes hands.

The capacity question nobody has answered yet

What the launch did not include is detail on how AI screening will be resourced, which systems each port will actually run, or how flagged containers will be handled differently from today. Fourteen ports on three continents, each with its own customs regime and inspection capacity, won't align on data standards overnight.

For carriers and forwarders, the near-term effect is likely uneven: Houston, Busan and Hamburg may move at different speeds than the French trio of Marseille, Le Havre and Dunkirk. Shippers moving high-risk trade lane cargo — Latin America to Europe above all — should expect more scrutiny before the network produces more convictions.

Still, the direction is set. Intelligence-led, port-to-port container screening is now official G7 policy, and the fourteen founding ports give it enough scale to matter on the routes where cocaine and precursor chemicals actually move.
