In a significant escalation of trade tensions between the United States and China, President Donald Trump announced that the U.S. will impose a 100% tariff on Chinese imports starting November 1, 2025, or possibly sooner. At the same time, the administration plans to enforce new export controls on “critical software” produced in the United States, targeting technology that Beijing could use in military or advanced systems.

The moves come in response to China’s recently expanded export controls on rare earth elements and critical minerals—materials essential to semiconductors, electric vehicles, defense systems, and advanced electronics. Chinese rules now require foreign firms to seek Chinese approval for exporting products containing even trace amounts of restricted minerals. (Reuters)
Below is a breakdown of what this means, reactions across markets and governments, risks for tech industries, and possible paths forward.
Background: China’s Export Controls on Rare Earths
China has historically dominated global rare earth mining and processing. In recent weeks, Beijing expanded its export control regime to include a broader set of minerals and materials,alongside stricter licensing requirements. (Financial Times)
U.S. and allied officials have called the move coercive, warning it could force supply chain realignment. (Reuters)

Key Elements of Trump’s Announcement
-
100% Tariff on Chinese Imports
Trump’s post on Truth Social stated that starting November 1—or potentially earlier—the U.S. would impose a 100% levy on Chinese goods on top of existing tariffs, which currently average around 30%. (Reuters) -
Export Controls on Critical U.S. Software
The administration also announced it will impose export restrictions on all critical software developed in the U.S., especially if it has potential dual uses in defense or advanced computing. (Reuters) -
Conditional Timing
Trump noted the effective date could be adjusted depending on China’s actions in the coming weeks. (Reuters) -
Market Reaction
The announcement rattled markets—with major U.S. tech stocks and indices falling in response. (AP News)
International & Chinese Reaction
-
China’s Stance
China criticized the move as escalatory and warned it would respond with countermeasures. The Commerce Ministry reaffirmed that the export controls are necessary for national security and accused the U.S. of threatening economic retaliation. (Politico) -
U.S. Officials Speak Out
While some officials express desire to avoid a full-blown trade war, many signal readiness to act. U.S. Trade Representative Jamieson Greer and Treasury Secretary Scott Bessent have criticized China’s export licensing policies and hinted that U.S. measures may be coordinated with allies. (Reuters) -
Global Spillover
Nations reliant on Chinese supply chains—especially in electronics, consumer goods, and automotive sectors—are watching closely. Firms dependent on access to rare earth materials or Chinese components may need to hedge or diversify.
Risks & Impacts on Tech and Trade
-
Supply Chain Disruption
A 100% additional tariff would double the cost burden on Chinese imports, affecting everything from consumer electronics to raw materials. Combined with China’s export licensing, many tech manufacturers may face delays or input shortages. -
Retaliation & Escalation
China could impose retaliatory tariffs, regulatory barriers, or export restrictions of its own. That may deepen a trade confrontation and force further decoupling. (Politico) -
Impact on U.S. Tech Exports
U.S. firms could suffer from reduced access to Chinese markets. Export controls on software may limit companies’ abilities to sell advanced tools or collaborate with Chinese firms. -
Market Volatility
Already, major tech stocks and indices have seen sharp moves. The threat of further escalation injects uncertainty into investments, supply contracts, and margins. (The Times of India) -
Strategic Shifts & Decoupling
The move accelerates the push toward “de-risking” or partial decoupling from China. Companies might explore alternative suppliers in Southeast Asia, India, Australia, or return production domestically. (Financial Times)
Possible Paths Forward & Scenarios
Diplomatic Negotiation
A scheduled meeting between Trump and Xi at the upcoming APEC summit may be a key moment for de-escalation. If China reverses some export control steps, the U.S. may delay or soften tariffs.
Partial Implementation & Phased Rollout
Trump’s conditional timing suggests that some elements of the 100% tariff or export controls may be rolled out gradually or selectively.
Coordination with Allies
The U.S. may seek cooperation from the EU, Japan, South Korea, Australia, and other nations impacted by supply chain disruption to form a counterbalance to China’s leverage.
Retaliation from China
China could employ countermeasures—tariffs, quotas, export bans—that hurt U.S. farmers, manufacturers, or tech companies.
Supply Chain Realignment
Firms may accelerate shifting production or sourcing to non-Chinese regions, adopt alternative materials, or invest in recycling of rare earth usage.
