The United States has accused more than 40 countries of helping Chinese exporters bypass American tariffs by routing goods through markets that face lower import duties.
The allegation, contained in a White House report, has intensified scrutiny of global supply chains and could create fresh pressure on countries with deep manufacturing and trading links to China.
The countries named in the report include Canada, India, Mexico, Japan and South Korea. According to the White House, goods worth between $30 billion and about $300 billion may have been redirected through third countries to reduce the tariff burden on Chinese exports.
US trade adviser Peter Navarro said the practice had cost the United States American jobs and billions of dollars in tariff revenue.
The Chinese embassy in Washington rejected the broader approach taken by the US, warning that trade wars have no winners. Beijing said it opposed US tariff measures and the use of state power to target Chinese companies.
The dispute centres on transshipment, a legitimate logistics practice that involves moving goods through an intermediary country before they reach their final destination. Washington alleges that Chinese exporters have exploited the system by using third countries as stopovers and, in some cases, repackaging products to conceal their actual origin.
The White House described the alleged activity as a sophisticated global network designed to evade US tariffs.
The report also said the United States is deploying artificial intelligence tools to identify suspicious trade flows and detect potential tariff evasion.
Global Supply Chains Under Greater Pressure
The allegations highlight the growing risks facing businesses operating across complex international supply chains.
China remains deeply integrated into manufacturing networks across Asia and other regions. As US tariffs on Chinese goods have increased, companies have increasingly examined alternative production locations and trading routes.
However, the White House argues that some changes in trade flows go beyond genuine supply chain diversification.
Chang Pao Li, an associate professor of economics at Singapore Management University, said the report could strengthen Washington’s negotiating position ahead of future discussions between the US and China.
She noted that Washington could argue that China continues to maintain indirect access to the American market through third countries. That could push the US to demand that any broader trade agreement address not only direct Chinese exports but also third country routing.
At the same time, legitimate supply chain restructuring could become harder to distinguish from deliberate tariff avoidance.
Economies that remain heavily integrated with Chinese manufacturing could therefore face additional compliance costs, scrutiny and potential trade restrictions.
New Risk for Asian Manufacturing Hubs
The dispute is particularly significant for countries that have become important links between Chinese manufacturers and Western consumers.
Mexico, India, Vietnam and other manufacturing centres have attracted investment as companies seek to diversify production and reduce exposure to geopolitical tensions.
For African economies seeking to attract manufacturing investment, the developments also offer an important lesson.
Businesses and governments looking to position Africa as an alternative production base will need to demonstrate clear product origin, transparent customs processes and reliable supply chain documentation.
The growing use of artificial intelligence in trade enforcement could make these requirements even more important. Governments with weak customs data systems may face greater difficulty proving that goods genuinely originate within their borders.
For African exporters, this could make digital customs infrastructure and traceability increasingly important competitive advantages.
Tariff Conflict Continues
The latest White House report comes amid continued tensions between Washington and Beijing.
Although the two countries previously agreed to pause many tariffs following negotiations, they have continued to impose restrictions on strategic products and technologies.
The US has also pursued new tariff measures through alternative legal mechanisms after earlier sweeping tariffs faced legal challenges.
The broader dispute has moved beyond traditional goods such as consumer products and industrial equipment. Technology, robotics, drones and other strategically important sectors have increasingly become part of the confrontation.
The coming negotiations between US President Donald Trump and Chinese President Xi Jinping are therefore likely to involve more than the headline tariff rates.
Trade routes, supply chain transparency, manufacturing locations and the treatment of Chinese goods moving through third countries could all become important bargaining points.
For global businesses, the message is increasingly clear. The location where a product is shipped from may no longer be enough to determine how regulators assess its trade origin.
As governments deploy more sophisticated data and artificial intelligence tools to monitor international commerce, companies will face growing pressure to prove where their products are made, how they move and whether their supply chains comply with changing trade rules.
