China has extended two trade barrier investigations into US measures that Beijing says disrupt global production and supply chains and restrict trade in green products, citing the complexity of the cases.
China’s Ministry of Commerce said the investigations, originally launched on March 27, 2026, will now run until Dec 27, 2026 under the country’s foreign trade barrier investigation rules.
One investigation focuses on US measures that China says are damaging global industrial and supply chains, including restrictions or bans on Chinese products entering the US market, controls on exports of high-technology products to China, and curbs on investment in key sectors.
A separate probe covers US measures that Beijing says hinder trade in green products.
According to the ministry’s original March announcement, the measures under review include restrictions on exports of green products to the US, delays to the deployment of new-energy projects and limitations on technological cooperation related to green products.
The ministry said preliminary information suggested that some of the measures could seriously affect the trade interests of Chinese enterprises and may conflict with World Trade Organization rules or other economic and trade agreements involving both countries.
China’s Commerce Ministry said the extensions were necessary because of the complexity of the investigations.
The move prolongs regulatory scrutiny of US trade and technology policies at a time when commercial ties between the world’s two largest economies remain strained by restrictions covering advanced technology, investment and clean-energy supply chains.
