China has widened its lead in liner-shipping connectivity, according to new data published by the United Nations, extending an advantage that has shaped how carriers deploy capacity and how shippers route cargo through the world's largest export market.

The finding comes from the UN's latest connectivity dataset, which tracks how well countries are plugged into global liner shipping networks — the number of scheduled services, the vessels deployed on them, their carrying capacity, and the range of destinations served directly. China already topped that ranking by a wide margin. The new data shows the gap has grown further.

For shippers, connectivity is a practical commercial variable, not an abstract score. A country high on the index offers more direct sailings, more carrier options, larger vessels on trade lanes and — critically — more schedule resilience when disruptions force rerouting. A widening Chinese lead means exporters based in China continue to enjoy the densest menu of departures and destinations in the market, while shippers consolidating cargo elsewhere face thinner direct networks and more transshipment exposure.

For carriers, the data underlines where fleet economics point. The largest vessels and the most frequent strings remain anchored on services touching Chinese ports, because that is where the box volumes justify them. That concentration reinforces itself: dense connectivity attracts cargo, and cargo attracts more capacity.

The UN connectivity measure has tracked China's rise for more than a decade. The country overtook its nearest rivals years before the pandemic, and every major shock since — port congestion in 2021, the demand collapse and rebound, the Red Sea diversions — has tended to entrench the pattern, because carriers protecting utilization cut thinner secondary loops first and defended their core China-centric services.

The commercial read-through for forwarders is straightforward. Bookings originating or terminating in China carry the most routing flexibility and the most competitive rate competition between operators. Cargo moving to or from less-connected markets pays for that density indirectly, through transshipment time, additional handling and reduced negotiating leverage.

The new figures arrive as the industry digests a period of heavy newbuild deliveries and softening spot rates on the major east–west lanes. In that environment, carriers have redrawn networks repeatedly, and the UN data suggests those redrawings have, on net, concentrated rather than dispersed connectivity around China.

Further releases from the UN dataset will show whether the trend holds as carriers digest overcapacity, whether via blank sailings, network consolidation or the scrapping decisions expected later in the cycle.
