As of April 2025, China’s manufacturing engine is pumping out more steel, electric vehicles, solar panels, and batteries than buyers at home or abroad can currently use. The gap, documented by economists for years, has grown so wide that Beijing’s traditional export safety valve is squeezing shut under rising tariff barriers.
Data from the Federal Reserve shows China’s trade surplus hit a record $1.2 trillion in 2025. While a surplus this large often signals economic strength, it also reveals a structural mismatch: Chinese factories produce far beyond what domestic consumers purchase, and the difference is shipped abroad at prices few foreign competitors can match. This dynamic is now fueling trade disputes across multiple continents.
A Widening Gap in Clean Energy
China’s clean energy sector illustrates the scale of the mismatch. The country’s electrolyser manufacturing capacity — used for hydrogen production — was eight times global shipments in 2021. By 2024, that multiple jumped to 18 times annual global shipments, according to industry estimates. China now controls nearly 60% of global electrolyser manufacturing capacity.
Steel tells a similar, older story. In 2023, China produced just over one billion metric tons of steel, exporting around 90 million tons. The OECD projects global steel overcapacity will reach 644 million tons in 2025 — more than the combined output of all OECD nations.
Electric vehicles are the most visible sector to ordinary buyers. Chinese EV exports topped 2.5 million units in 2025, nearly double the previous year. Industry estimates suggest China holds spare capacity to double its EV and lithium battery exports again from current levels.
The overhang extends far beyond these headline sectors. A European Parliament study found 51% of surveyed firms expect overcapacity in chemicals, 55% in industrial machinery, 56% in pharmaceuticals, and 62% in automotive.
Root Causes: Model in Need of Reset
China’s overcapacity is not new. It dates back to market reforms in the 1990s and worsened after the 2014–2016 construction stimulus. What makes 2025 different is the breadth of affected sectors and the intensity of partner retaliation.
The growth model has long relied on investment-heavy industrial expansion, backed by state subsidies, cheap credit, and procurement rules favoring domestic firms. This combination builds capacity quickly but does not match that capacity with actual demand — especially when Chinese households, squeezed by a weak property market, are not spending enough to absorb factory output.
When domestic demand falls short, exports have traditionally filled the gap. That pathway is narrowing. In March 2025, the European Union imposed additional tariffs of up to 38% on Chinese EVs, escalating trade friction. The United States is considering similar measures on Chinese solar panels and steel, building on existing tariffs.
Chinese solar manufacturers already show the strain. They posted financial losses in 2024 and 2025 despite record export volumes — evidence that even strong global demand for renewable energy is insufficient to absorb China’s oversupply at profitable prices.
Redirecting Exports to the Global South
As Western markets grow more resistant, China has shifted its excess output toward developing economies. Weak domestic demand and rising barriers in the West have pushed Chinese exporters deeper into the Global South, often at heavily subsidized prices. For Beijing, the logic is to keep factories running, support employment, and maintain utilization rates.
The consequences for recipient countries are mixed. Some analysts argue that cheap, subsidized Chinese products help developing economies by providing affordable infrastructure, electronics, and manufactured goods. Others contend the same flood of subsidized goods undermines the ability of these countries to build their own manufacturing bases.
Pakistan is a case in point. It simultaneously courts Chinese manufacturing investment under the second phase of the China-Pakistan Economic Corridor (CPEC) while trying to shield domestic industries — especially textiles — from being undercut by cheap Chinese imports. Pakistani cotton and textile associations have flagged concerns this year about under-invoiced Chinese yarn and fabric entering local markets at prices domestic producers cannot match. China’s overcapacity problem forms the backdrop to these specific complaints.
Not All Overcapacity Is Wasteful
Economists caution that not everything labeled “overcapacity” reflects wasteful overproduction. In fast-growing sectors like EVs and batteries, global demand is expanding quickly enough that today’s spare capacity could become necessary supply within a few years.
China’s semiconductor production offers a partial counterexample: several assessments show fab utilization rates matching or exceeding global averages, suggesting less evidence of deliberate market flooding in that sector than critics sometimes claim.
Nevertheless, the volume of Chinese manufactured exports is large enough to reshape competitive dynamics in whichever market absorbs them.
What Beijing Has Tried — and What Remains Unresolved
China has floated several remedies: boosting domestic consumption, shifting manufacturers toward higher-value output, and expanding outbound investment so Chinese firms build factories abroad instead of shipping finished goods from home.
Each approach has its own obstacles. Chinese households remain cautious spenders. Quality upgrades do not fix a demand shortfall. Outbound investment takes years to meaningfully shift where production actually occurs.
For now, exports remain the easiest lever to pull — even as each pull draws more tariffs and scrutiny from trading partners who increasingly see China’s overcapacity as their problem, not only Beijing’s. Who ends up buying what China can produce, and at what cost to the industries competing against it, is still being worked out one trade dispute at a time.
