China launches investigations into US trade practices. Why now?
Beijing responds to US Section 301 probes with its own six-month investigations into green tech and supply chain restrictions.
China's Ministry of Commerce announced two formal trade barrier investigations targeting the United States, marking a significant escalation in ongoing trade tensions. The probes, launched on March 27, 2026, are a direct retaliatory response to recent US Section 301 investigations that could lead to Washington reimposing higher tariffs on Chinese goods. Beijing's investigations will specifically examine US measures that allegedly harm global industrial and supply chains, with a particular focus on restrictions obstructing trade in green products and technologies.
According to the ministry's statement, preliminary evidence suggests the US may have restricted or banned Chinese goods from its market, curbed exports of advanced technology products to China, limited two-way investment in critical sectors, slowed new energy project rollouts, and restricted cooperation on green technology. If confirmed, China claims these practices would "seriously harm" Chinese companies and potentially violate World Trade Organization rules and past bilateral agreements. Both investigations have a six-month timeline, extendable once by up to three months, mirroring the structure of a recent probe China concluded against Mexico.
This move represents a strategic shift from China, which has historically been more defensive in trade disputes. By launching proactive investigations focused on green technology—a sector where China holds significant manufacturing advantages—Beijing is attempting to counter US pressure points while positioning itself as a defender of global trade rules. The timing suggests coordinated economic statecraft, coming just as the US prepares potential tariff actions.

Why It Matters
Escalating trade investigations could lead to new tariffs, disrupting global supply chains and green technology development critical for climate goals.
