Two Infrastructure Projects, Two Bottlenecks Removed: Hainan Enters Aircraft Recycling While the Yangtze Gets a Bigger Lock

Two Chinese infrastructure projects launched this month target different industries but share a common logic: removing physical and regulatory constraints that have capped capacity in sectors with measurable demand.

Hainan: From repairing jets to dismantling them

On June 13, Grand China Aviation Maintenance, a subsidiary of HNA Technic, launched Hainan Free Trade Port's first aircraft dismantling facility at the One-Stop Aircraft Maintenance Base in Haikou. The site fills a specific gap. Hainan could already repair and modify aircraft. It could not take retired planes apart, test their components and sell the parts into the global market for used serviceable materials. That gap is now closed.

The economics are shaped by Hainan's customs regime. Full island-wide special customs operations, in effect since December 2025, apply zero-tariff treatment and streamlined import procedures to goods entering and leaving the port. For an aircraft dismantler, that reduces the cost of bringing retired airframes — often registered and stored outside China — onto the island, and of shipping refurbished parts back out to airlines, lessors and maintenance providers. The global secondary market for serviceable components is deep: engines, landing gear, avionics and thousands of other certified parts trade in a network currently dominated by facilities in the United States, Europe and the Middle East. Hainan's entry adds a new node with a structural cost advantage.

The Jiangdong New Area Administration Bureau, where the maintenance base is located, expects the dismantling line to draw more aviation services companies to the island as component trading and logistics develop. For HNA Technic, the facility extends an existing MRO (maintenance, repair and overhaul) franchise into the downstream of the aircraft lifecycle.

Yangtze: Doubling the lock capacity on a 4.2-billion-tonne waterway

The Yangtze River is the world's busiest inland waterway by cargo volume, handling 4.2 billion tonnes annually — a figure that has risen 71% over the past decade. The Three Gorges Dam locks have been operating at the limit of their 170-million-tonne annual throughput capacity for years. The new waterway project, the first major infrastructure investment of China's 2026–2030 planning cycle, is the physical answer.

When complete, Three Gorges annual throughput capacity will reach 336 million tonnes. Capacity at the Gezhouba Dam downstream will rise to 360 million tonnes. The upgrade will allow 10,000-tonne vessels to navigate directly from Chongqing, deep in China's interior, to Shanghai on the Pacific coast, eliminating the need to transfer cargo to smaller vessels or switch to rail and road at the dam. That trans-shipment step currently adds time and logistics cost to supply chains that depend on the river.

The economic weight of the corridor the Yangtze serves is the commercial rationale. The Yangtze River Economic Belt now accounts for 47.3% of China's GDP, up from 42.2% a decade ago. The manufacturing output concentrated along the river — automotive, electronics, industrial machinery — moves by water because it is the most energy-efficient freight mode per tonne-kilometre. Expanding lock capacity lowers the logistics cost base for those industries and connects the interior more directly to export ports.

Gao Peng, deputy chief engineer of the China Three Gorges Corporation, the project's implementing entity, said the development would be built to standards of quality, environmental protection and safety. Niu Xinqiang, an academician of the Chinese Academy of Engineering, noted that the waterway would also be integrated with north-south rail and road networks, creating a connected transport grid rather than a standalone corridor.

The two projects operate in different sectors — aviation circular economy and inland waterway freight — but their commercial logic is the same. Each removes a known infrastructure ceiling. In Hainan, that ceiling was regulatory: the island had the maintenance capability but not the customs framework to make dismantling profitable. On the Yangtze, it was physical: the locks could not pass the volume of cargo the economy was generating. Both ceilings have now been addressed.
