Charted: China Delivers 54.6% of World Ship GT — Greece Still Owns More Fleet

The world’s merchant fleet is financed in Athens, Geneva, and Singapore — and welded in Shanghai, Busan, and Imabari. That split is the industrial story UNCTAD’s Review of Maritime Transport keeps reprinting, and 2024 made it sharper: Chinese yards delivered 54.6% of global gross tonnage (GT), the Republic of Korea 28%, and Japan 12.6%. Together the East Asian trio shipped 95.2% of new merchant-ship capacity. Everyone else — Europe’s cruise specialists, Viet Nam, the Philippines, India, the United States — shared the remaining rounding error.

This post asks a two-part question: who delivers the world’s new merchant-ship capacity, and who owns versus builds? GT measures the physical size of vessels leaving yards. Deadweight tons (dwt) measure carrying capacity on the water. Beneficial ownership asks which country’s companies control that capacity — regardless of flag. The interactive dashboard above stacks those ledgers so the build map and the own map cannot be confused.

The 2024 delivery scoreboard

UNCTAD’s Table II.6 (Clarksons Research underlying) records 71.7 million GT of propelled seagoing merchant vessels (≥100 GT) delivered in 2024 — roughly 10% more tonnage than 2023 and 8.8% more vessels. Country shares:

China alone out-delivered Korea and Japan combined. That is not a soft majority: it is a structural lead. In 2023 China crossed 50% of world GT for the first time on UNCTAD’s series; 2024 pushed the print to the mid-fifties. Korea held roughly steady near 28%. Japan slipped from 14.9% to 12.6%. The long arc — Japan’s ~50% era in the 1970s–80s, Korea’s mid-2010s peak near 35%, China’s post-2010 surge — is the industrial succession story of heavy manufacturing.

Minor builders matter as footnotes and as policy aspirations. UNCTAD’s overview table puts the United States at 0.04% of 2024 commercial GT output, India at 0.06%, Italy at 0.64% (cruise and passenger niches), and Germany at 0.26%. Naval shipbuilding is a different industry; commercial GT is the ledger that renews the global trading fleet.

Segment leadership: China everywhere except gas

Gross tonnage is not one market. Containers and bulk carriers dominated 2024 deliveries — 41.3% and 26.6% of world GT respectively — with gas carriers at 12.2% and oil tankers a thin 5.1%. Inside that mix, leadership flips by segment:

• Containers: China led with ~16.6M GT versus Korea’s ~11.3M and Japan’s ~1.7M. China’s container surge also showed up in 2023, when UNCTAD noted China overtaking Korea in the container segment.
• Bulk carriers: China ~12.5M GT; Japan a strong second at ~5.7M; Korea’s print is negligible in the published table. Japan’s remaining franchise is still heavily bulker-tilted.
• Gas carriers: Korea remains the specialist~6.8M GT against China’s ~1.7M and Japan’s ~0.2M. UNCTAD’s contracting narrative for 2024 still flags gas as the segment where China does not hold first place.
• Oil tankers: A closer China–Korea race (~1.5M vs ~1.3M GT), with Japan a distant third.

The strategic read is simple. China’s lead is broadest in the volume segments that move dry cargo and boxes. Korea’s remaining moat is high-value gas and a deep book in complex hulls. Japan is defending a bulker franchise while losing share overall. Europe’s yards still matter for cruise ships and niche passenger tonnage — visible in vessel counts and value, not in GT share.

Build versus own: Greece’s ledger is not China’s yard

If you stop at deliveries, you miss the ownership map. As of 1 January 2025, UNCTAD’s beneficial-ownership ranking (vessels ≥1,000 GT) still puts Greece first at 16.4% of world dwt (~398 million dwt), ahead of China at 14.4% (~347 million dwt) and Japan at 9.9% (~241 million dwt). Singapore, Hong Kong (China), and Korea follow. European owners as a group still control about a third of carrying capacity; Asian owners about half.

That is the core paradox of maritime industrial power:

• China builds ~55% of new GT and owns ~14% of the fleet.
• Korea builds ~28% and owns ~4%.
• Japan builds ~13% and owns ~10%the closest build/own alignment among the big three.
• Greece builds essentially nothing commercial at world scale and owns ~16%.

Ownership is a capital-markets and chartering story. Building is a steel-throughput, labor, and industrial-policy story. Greek owners order in Asia; Chinese state and private owners order preferentially at home; Korean yards sell complex tonnage to global buyers. Flags complicate the picture further: Liberia, Panama, and the Marshall Islands still hold the top three registers, with open registries accounting for the majority of world capacity — so “where the ship is flagged” is rarely “where the owner sits” or “where the hull was welded.”

Orderbook lock-in: deliveries understate the pipeline

Deliveries lag contracts by years. UNCTAD, citing Clarksons, reports that China took 74.4% of contracted GT in 2024 and held 63.7% of the global orderbook by GT at the start of 2025. Active Chinese yards (~120) hold roughly 45% of global yard capacity but about 60% of the orderbook — a mismatch that means Chinese slots are fuller relative to physical capacity than competitors’. The global orderbook stood near 15% of the active fleet early in 2025 — moderate versus the 2009 bubble (~52%), but concentrated.

Yard consolidation is the other half of concentration. About 348 yards secured contracts or completed deliveries in 2024 — roughly half the 2007 peak near 739. Fewer yards, more GT in China, and elevated newbuilding prices together raise switching costs for owners who might wish to diversify builders for geopolitical reasons. UNCTAD’s 2025 chapter is explicit: a rapid short-term switch away from Chinese capacity is difficult.

Policy is noticing. The United States has floated port fees aimed at Chinese-linked operators and Chinese-built vessels; India announced a multi-billion-dollar maritime development fund; Korea is relaxing immigration rules and outsourcing some production; Russia is planning a large domestic newbuild program. None of those moves rewrite 2024’s GT shares overnight. They do change the risk premium attached to Chinese-built tonnage calling at certain ports — a financial and routing variable, not an instant relocation of dry docks.

Who wins, who is exposed

Winners of the current map: Chinese yards and their domestic supply chains; Korean yards in gas and complex tonnage; Greek and other European owners who can still shop Asia for cheap, fast slots; charterers who benefit from abundant new container and bulker supply.

Exposed: owners concentrated in Chinese-built fleets if destination-port fees or insurance differentials widen; Korean and Japanese yards fighting labor and cost inflation while China expands capacity toward ~1,700 ships/year of global nameplate (BRS via UNCTAD); US and Indian commercial ambitions starting from sub-0.1% GT shares; any analyst who treats “China owns shipping” as synonymous with “China builds ships.”

The contrast with industrial robot installation geography is useful: robots concentrate where factories automate; ships concentrate where steel and wet docks scale. Both are heavy-industrial capacity stories. Only one still has Greece at the top of the ownership table.

What would change the story

Several observables would force a rewrite:

1. China’s delivery share falling back below 45% for two consecutive yearsevidence that Korea/Japan (or newcomers) are reclaiming volume, not just niches.
2. Korea losing gas-carrier leadership in contractingthe last major segment China does not already lead.
3. US or Indian commercial GT share rising above 1%a real industrial foothold, not a press release.
4. Greece’s ownership share falling below China’s while Chinese build share stays above 50%ownership catching up to yards.
5. Sustained orderbook diversificationChina’s orderbook share dropping toward its yard-capacity share (~45%) rather than sitting near two-thirds.

Until one of those prints, the default forecast is more of the same: East Asia welds almost everything; Greece and a handful of Asian owners finance and control a surprising share of what floats; open registries fly the flags.

Caveats and methodology

• GT ≠ dwt ≠ value. Gross tonnage measures enclosed volume (useful for shipbuilding output). Deadweight measures cargo capacity (useful for ownership and trade). Fleet value rankings can reorder countriesChina leads ownership by value in some UNCTAD tables even when Greece leads by dwt.
• Coverage thresholds differ. Delivery tables cover merchant vessels ≥100 GT; beneficial-ownership tables typically start at ≥1,000 GT.
• 2023 China “>50%” is UNCTAD’s milestone language; we chart it as 50.0% for the 2023 milestone point. The precise 2023 decimal is less important than the crossing.
• Share milestones (1980 Japan era, 2016 Korea peak) are narrative benchmarks from UNCTAD/BRS citations, not a reconstructed annual seriesthe dashboard labels them as such.
• Europe in the 2024 delivery strip is UNCTAD’s aggregate column, not a single national yard system; Italy and Germany appear separately in the minor-builder overview.
• Korea bulk-carrier “NA” in Table II.6 is treated as zero in segment stacks; do not over-read a blank cell as a disclosure of zero capability in other years.
• Clarksons Research underlies UNCTAD’s calculations; revisions in later Clarksons pulls can shift decimals without changing the concentration story.

The shareable takeaway

In 2024 China delivered 54.6% of the world’s new merchant-ship GT — more than Korea and Japan combined — while the East Asian trio shipped 95%. Greece still owns more fleet carrying capacity than China. Building steel and owning ships remain different maps, and the orderbook says China’s build lead is still widening.
