US and China Face a New Trade Flashpoint Over Rare Earths and Trump's 100 Percent Tariff Threat

A November deadline puts the trade truce under pressure

President Donald Trump's threat to impose an additional 100 percent tariff on Chinese goods from November 1 has brought the United States and China back to the edge of a sharper trade conflict. The immediate trigger was Beijing's expansion of export controls on rare earth minerals, materials used in products ranging from smartphones and electric motors to fighter aircraft.

As of October 15, 2025, the confrontation is putting pressure on a planned late October meeting between Trump and Chinese President Xi Jinping in South Korea. Trump initially suggested there might be no reason to meet Xi, then softened his position over the weekend. Treasury Secretary Scott Bessent said talks were continuing and the meeting remained likely.

China's commerce ministry accused Washington of double standards, arguing that the United States uses national security to justify restrictions on Chinese businesses while challenging Beijing's use of the same reasoning. A ministry spokesperson warned that China would take corresponding measures if the new American duties went ahead.

Investors have already felt the uncertainty. US stocks fell sharply on Friday after the tariff threat, wiping out more than a trillion dollars in market value, then rebounded Monday as officials signaled that negotiations were continuing. Asian markets finished lower Monday, reflecting concerns about another disruption to trade and manufacturing.

The dispute now reaches beyond taxes on imports. Export licenses, restrictions on software and aircraft parts, antitrust investigations, and fees on ships are all part of the confrontation. For manufacturers, the immediate problem is whether essential materials and components will arrive on time, and how much they will cost when they do.

What changed in China's rare earth rules?

China announced its expanded rare earth export controls last week. Authorities added more elements to the controlled list, tightened approvals for users in semiconductors and other advanced manufacturing, and introduced stricter licensing thresholds. Beijing defended the changes as measures to protect national security.

Foreign companies could need Chinese approval when even a small share of a product's value comes from rare earths processed in China. A licensing requirement means a company must obtain government permission before a covered shipment can proceed. That creates another decision point between placing an order and receiving the material.

Beijing also said it would deny export licenses when materials would support foreign militaries. The rules therefore reach both commercial supply chains and defense production, where manufacturers depend on specialized materials for equipment that can take years to develop.

Additional controls cover technologies used in mining, separation, magnet making and recycling. Separation is the processing needed to extract individual rare earth elements from a mixture. Restrictions on those technologies extend the dispute beyond shipments of minerals to the methods used to produce and reuse them.

China said it had informed Washington before announcing the controls. Both capitals were also preparing exemptions for certain categories or firms. The expanded licensing regime takes greater effect in the weeks ahead, but the account of the measures did not give a precise date for every additional requirement.

Why factories and defense suppliers depend on these materials

Rare earths are not especially rare in the ground. The concentration of refining and magnet production in China is what makes access difficult to replace quickly. China accounts for a large share of mining and an even larger share of processing, giving Beijing considerable influence over availability and prices.

Manufacturers use these elements in powerful magnets for electric motors and wind turbines, compounds that polish smartphone glass, and catalysts used in petrochemical refining. Automakers, chip companies and other advanced manufacturers depend on supply chains that pass through China.

Defense equipment also relies on rare earths. Fighter aircraft, guided munitions, radars, submarines and drones contain magnets or other components using these materials. A licensing policy that excludes foreign militaries or their suppliers can delay production and increase costs for contractors and allied defense industries.

Gracelin Baskaran, a critical minerals scholar at the Center for Strategic and International Studies, described the controls as a strategic negotiating tool. She warned that continued restrictions could impair military readiness over the medium term.

It undermines the development of the defense industrial base at a time of rising global tension. It is a very powerful negotiating tactic because it touches national security.

The Pentagon has backed new refining capacity and supplier agreements in North America, Australia and allied countries. Mining projects and magnet plants take time to build, while environmental permitting can add more years. Those delays leave manufacturers exposed to China's licensing decisions in the near term.

Jeremy Siegel, professor emeritus of finance at the University of Pennsylvania, argued that the United States should have prepared sooner for a possible supply squeeze. He pointed to China's share of refining and the absence of a US strategic reserve.

It is scandalous that we do not have a rare earths strategic reserve, that China refines 90 percent of these materials. Where were we?

Restrictions were building before the tariff threat

Washington introduced new export limits on Chinese firms late in September. It also weighed restrictions on aircraft parts sales and signaled possible constraints on flight paths for Chinese airlines operating some US routes.

Beijing's responses included tighter controls on critical minerals, antitrust investigations involving US companies, and plans for additional port fees on vessels linked to the other country. Antitrust investigations examine whether companies have used their market position in ways that restrict competition.

Trump's latest response added the possibility of US export controls on critical software. His proposed additional tariff would take many imports into triple digit percentage rates, adding to duties already imposed under other policies.

National security has become the stated reason for many of these actions. Each government argues that particular technologies, materials or business relationships need tighter supervision. Companies operating across both markets face the practical consequences: more approvals, higher costs and greater uncertainty about future orders.

The pressure also reaches universities and suppliers of sensitive equipment. Earlier in 2025, US officials revoked some student visas, urged companies to restrict shipments of sensitive equipment, and pressed allies to tighten technology sales to China. Beijing adjusted its licensing environment and opened investigations involving firms linked to the United States.

How the confrontation unfolded in 2025

The latest dispute follows a year of escalating tariffs and temporary pauses. A lull in late summer gave way to renewed confrontation in the fall, while four rounds of negotiations in Europe helped contain earlier outbreaks.

The main stages were:

• January and February: Tariffs rose across a broad range of goods. Washington imposed a new universal tariff and increased levies on Chinese imports. Beijing responded with duties on US agricultural and industrial products and controls on metals and minerals used in advanced manufacturing.
• Early spring and April: Headline tariff rates on some categories reached levels that effectively stopped trade in those goods. Both countries accumulated tariffs and other restrictions, pushing effective duties on many products far above levels before 2018.
• May, Geneva: Negotiators agreed to a pause lasting 90 days and reduced reciprocal tariffs from their extreme peaks. Effective rates on many Chinese goods fell to roughly 30 percent.
• June, London, and July, Stockholm: Talks continued on export licensing and sensitive industries, including rare earths, semiconductors and pharmaceuticals.
• September, Madrid: A fourth negotiating round kept the diplomatic process moving, while new US export restrictions late in the month added pressure.
• October: China's expanded rare earth controls prompted Trump's threat of an additional 100 percent tariff and renewed uncertainty over the planned leaders' meeting.
• November 1: The White House identified this as the possible start date for the additional US tariff if talks stall.

The European meetings reduced immediate pressure without resolving the central disagreements. Working groups addressed export licensing, rare earth shipments, consumer technology platforms and fentanyl enforcement. Each round bought time, while disputes over trade practices, security and access to technology continued.

What higher tariffs mean for households and businesses

Tariffs are taxes paid by importers when goods enter a country. Importers may absorb some of the expense, charge business customers more or pass costs along to consumers. The price effect therefore reaches beyond the company bringing a shipment through customs.

Policy groups tracking the 2025 tariff burden estimate average US rates on Chinese goods at percentages ranging from the low 50s to the high 50s, depending on the calculation method and date. Comparable estimates put China's average duties on US goods at roughly a third of their value.

Those averages are well above the roughly 30 percent range reached for many Chinese goods after the Geneva pause. Individual products can face much higher rates because several policies may apply to the same shipment. The proposed additional 100 percent duty would sit on top of existing charges and take many imports into triple digits.

One study of the combined tariff regime in 2025 estimated an average tax increase of about $1,300 per US household this year. The estimated burden could rise in 2026 if further measures take effect. Households with low and middle incomes tend to feel these costs more acutely because goods account for a larger share of their spending than they do for the highest earners.

Researchers estimate a modest reduction in US gross domestic product from tariffs alone, with larger losses when foreign retaliation and supply chain adjustments are included. Gross domestic product, or GDP, measures the value of goods and services an economy produces. Retaliation can reduce exporters' sales, while changing suppliers or moving production adds costs for businesses.

Markets swing while growth forecasts hold up

The S&P 500 recorded its worst day since April during Friday's selloff. On Monday, it posted its biggest gain in a single day since May, recovering a substantial part of the losses after the White House indicated that talks were continuing and Trump said relations could improve.

Asia Pacific markets closed lower at the start of the week. Electronics, auto and semiconductor supply chains depend heavily on sourcing across borders, leaving businesses and investors sensitive to any change in access to Chinese materials.

Gold and silver prices surged as traders sought protection against policy shocks. Digital assets also experienced wide swings. Similar market movements had followed tariff announcements during the spring escalation, when small signs of easing tensions or fresh threats quickly moved broad stock indices.

The International Monetary Fund recently raised its forecast for global growth in 2025 to 3.2 percent. It cited milder tariff effects than expected, flexible supply chains and supportive financial conditions. Its forecasts put Chinese growth near the middle of the 4 percent range and US growth near 2 percent, with continuing strains in China's property sector weighing on its outlook.

The IMF warned that renewed US and Chinese escalation could reduce growth in 2026 and beyond. A more severe scenario would produce a much larger drag on the global economy by 2027. The improved 2025 forecast therefore sits alongside a warning about the costs of another round of restrictions.

Trade shifts toward other markets

Chinese exporters have increased sales in Southeast Asia, Latin America and Africa while shipments to the United States have declined for several months. Customs data show gains of more than 10 percent in exports to ASEAN countries and other regions.

Multinational manufacturers are also spreading orders across Vietnam, Malaysia, Mexico and Eastern Europe. Tariffs account for part of that shift. Companies have also sought to reduce their dependence on a single production location after disruptions during the pandemic.

Changing a supplier requires more than redirecting a purchase order. Manufacturers are qualifying second and third production sites, building reserve inventories of critical inputs and signing contracts to buy materials over longer periods from suppliers outside China. Some are redesigning products to use fewer controlled materials.

The Defense Department has been particularly active in securing domestic sources of rare earths and magnets. Commercial businesses are changing sourcing arrangements for batteries, electronics and vehicles. These preparations aim to keep production running when policy changes interrupt a supplier or make an existing route more expensive.

Ships and other countries face new pressure

New port fees on ships linked to each country's maritime trade are adding another layer of costs to global logistics. The measures are rolling out in stages and affect shipping routes that carry a large share of world trade. Limited exemptions still leave global shipping companies exposed when their vessels use US or Chinese ports.

Mexico, a major destination for Chinese auto exports, floated a large tariff on those vehicles after pressure from Washington. European officials rolled out higher steel duties to counter dumping and strengthen their position in negotiations with Washington and Beijing. Dumping refers to selling exports at prices judged unfairly low.

Canada, Brazil and Mexico took steps to protect domestic steelmakers as supply chains adjusted to new prices and quotas. India, facing US tariffs linked to its purchases of Russian oil, held prominent meetings with Chinese counterparts while considering its trade choices.

Governments from Seoul to Brussels to Mexico City face pressure to choose sides or negotiate exemptions for their industries. Businesses face a more divided trading environment, in which a decision in Washington or Beijing can change the costs of a shipment or the supply of a component far beyond either country.

Can diplomacy preserve the South Korea meeting?

China's commerce ministry has argued that threatening new measures while seeking negotiations is the wrong approach. Its spokesperson said Beijing would respond if the new triple digit tariffs took effect, while repeating that China preferred dialogue.

Resorting to tariff threats is not the right way to engage with China. Our position is consistent: we do not want a tariff war, but we are not afraid of one.

US officials describe their pressure campaign as an effort to change trade practices and stop the flow of illicit synthetic opioids. Treasury Secretary Scott Bessent said discussions had intensified and that a meeting between the two presidents remained possible later in October.

The talks went into overdrive over the weekend, and the Trump Xi meeting is still likely later this month. We want a durable arrangement that protects US interests and supports stability.

Trump paired his tariff threat with a more conciliatory weekend message on social media addressed to Xi. He said he wanted to help China rather than harm it.

Do not worry about China, it will all be fine. Highly respected President Xi just had a bad moment. He does not want a Depression for his country, and neither do I. The USA wants to help China, not hurt it.

The South Korea meeting remains on the calendar, although the tense atmosphere could disrupt the plans. The four European negotiating rounds have provided a way to ease immediate pressure. The challenge now is to reach another arrangement before the November tariff deadline and the further rollout of Chinese controls.

The choices before the November deadline

Washington and Beijing could extend the truce and focus negotiations on particular industries. Targeted export licenses for commercial technologies could be exchanged for more predictable rare earth shipments. Such an arrangement would reduce immediate disruption for manufacturers and farmers while leaving broader disagreements for later talks.

A second possibility is that the additional 100 percent tariff takes effect and China responds with countermeasures. Earlier in 2025, extreme headline rates were followed by temporary waivers and pauses. Another escalation could bring renewed market volatility before governments introduce exemptions to limit damage.

Both sides can also increase pressure without raising tariffs. China can change the speed of export licensing, expand investigations involving foreign firms or adjust port fees. The United States can tighten export controls, slow regulatory approvals or press allies on financing and standards.

Businesses find these measures harder to track and plan around than published tariff schedules. A duty provides a stated charge; a delayed license can leave a company uncertain about when an essential input will arrive. Companies are responding with additional inventories, alternative suppliers and changes to production locations.

November 1 is the next stated US tariff deadline. Before then, the planned late October leaders' meeting offers an opportunity to reduce the immediate pressure, while Chinese licensing requirements and staged shipping fees continue to shape business decisions.
