The smartphone in your hand, the car in your driveway, and the solar panels on a roof may have something in common: somewhere deep inside their supply chains could be materials linked to the forced labor of Uyghurs.
China is one of the world’s biggest manufacturing centres producing everything from clothing and electronics to electric vehicles and solar equipment. But behind this vast industrial network are growing concerns about forced labor and the treatment of workers, particularly in China’s Xinjiang Uyghur Autonomous Region.
The issue has drawn international attention because Xinjiang is a major producer of cotton, aluminium, silicon and other industrial materials. These materials can travel through several factories and companies before becoming part of a finished product. This makes it difficult for consumers and sometimes even companies—to know exactly where every component originated.
The U.S. Department of Labor currently lists 31 goods from China as being associated with child or forced labor. Twenty one of those are connected specifically to forced labor in Xinjiang. The list includes cotton, textiles, aluminium, polysilicon and other products used in global manufacturing.
Polysilicon is particularly important because it is a key material used in solar panels. The U.S. Department of Labor has reported allegations of coercive recruitment, restrictions on movement and surveillance involving workers connected to polysilicon production in Xinjiang.
Aluminium is another concern. According to U.S. government research, roughly 17% to 20% of China’s aluminium production comes from Xinjiang. Aluminium is widely used in automobiles, electronics, construction and other industries. If raw materials are produced under abusive conditions the problem can therefore extend far beyond the original factory.
But forced labor does not always mean workers are physically locked inside a factory. Under international labor standards, forced labor involves work demanded under the threat of punishment when a person has not freely agreed to perform it. Threats intimidation, restrictions on movement and the confiscation of identity documents can all be warning signs.
Reports from the United States and other governments have raised concerns about government backed labor transfer programs involving Uyghurs and other ethnic minorities in Xinjiang. Critics say some workers have been pressured into factory employment and subjected to surveillance and restrictions.
China strongly rejects allegations of systematic forced labor. Chinese authorities describe their policies in Xinjiang as vocational training poverty reduction and employment programs designed to improve people’s living standards. Beijing has also rejected accusations that its policies amount to human-rights abuses.
The disagreement highlights one of the biggest challenges facing journalists, governments and companies getting independent information from areas where access can be limited. It also means that claims about particular factories or products must be examined carefully rather than assuming that every product connected to Xinjiang was made through forced labor.
Still, governments are increasingly taking action. The United States passed the Uyghur Forced Labor Prevention Act in 2021, creating a presumption that goods produced wholly or partly in Xinjiang or by certain listed entities, were made with forced labor unless importers can demonstrate otherwise. In August 2025, U.S. authorities expanded enforcement to additional sectors, including copper, lithium, steel and other materials.
These measures are putting pressure on companies to look deeper into their supply chains. It is no longer enough to know the name of the factory that assembled a product. Companies increasingly need to understand where the raw materials came from and who produced them.
That is easier said than done. A single product can pass through dozens of suppliers and several countries before reaching a customer. A material mined or processed in one region may become a component in another factory and eventually end up inside a product sold thousands of miles away.
This is why the debate over China’s supply chains is not only about China. It is also about the responsibilities of multinational companies and consumers in a global economy built on complex networks of production.
The next time we pick up a smartphone drive an electric car or look at a solar panel the label tells us where the final product was assembled. It may not tell us the story of everyone who helped make it.
That is the question the global supply chain must now confront not simply where was this product made, but who made it and were they truly free to say no?
