Chinese President Xi Jinping is heading to the negotiating table with Donald Trump with a boost in bargaining power, after the US leader lost his ability to quickly raise tariffs for nearly any reason.

Weeks before Trump lands in Beijing on March 31, the first trip by an American president since his last visit in 2017, the Supreme Court invalidated his broad emergency tariffs — a key point of leverage over China. That’s eliminated Trump’s second-term levies on China and left Beijing facing the same 15% global fee applied to US allies, a rate that comes with a 150-day expiry date.

The removal of tariff threats, which last year escalated up to 145%, will make it harder for Trump to press Xi for larger purchases of soybeans, Boeing Co. aircraft and energy. It also leaves him without a key weapon to strike back if Chinese negotiators make fresh demands in return for allowing a steady flow of rare earth metals that are vital to US manufacturing.

“Ultimately, this Supreme Court ruling puts China in a much stronger bargaining position,” said Wu Xinbo, director at Fudan University’s Center for American Studies, citing the example of China’s commitment to buy some 25 million tons of soybeans, which was predicated on previous tariff negotiations. “If those tariffs are now deemed illegal, the ‘soybean card’ is back in China’s hand.”

Xi’s team will likely push harder for access to advanced semiconductors, the removal of trade restrictions on Chinese companies and reduced US support for self-ruled Taiwan, where Beijing’s focus is on arms sales and stronger language around opposing the island’s independence, added Wu, who previously advised the Foreign Ministry in Beijing. The Chinese Communist Party considers democratic Taiwan its own territory despite never having ruled it.

While Trump’s setback is a win for Xi, Chinese officials like others around the world have been cautious in their reaction. The Foreign Ministry in Beijing didn’t reply to a request for comment during a long public holiday, and state media has been measured in its reporting of the ruling.

US Trade Representative Jamieson Greer told the US maintains an average tariff of 40% on China, even without using the emergency law struck down by the court. Morgan Stanley estimates the average US tariff on China now stands at 24%.

Either way, the impact of US tariffs for Beijing was already blunted last year by exporters diversifying into other markets. China’s record $1.2 trillion trade surplus in 2025 surprised the world and defied Trump’s levies. By December, shipments from China to the US accounted for about 10% of its total exports, according to official Chinese data — half the share in 2018, when Trump launched his first trade war.

Corresponding Measures

Retaliation could still be on the cards. Beijing will assess corresponding measures if the US continues to impose new duties using other legal tools, according to Cui Fan, a former consultant to China’s Ministry of Commerce. The possibility can’t be ruled out that adjustments will be made if the US actually lowers tariffs, he was cited as saying by Yuyuantantian, a social-media account linked to China’s state broadcaster.

Mainland China’s markets are closed for Lunar New Year holidays and will reopen on Tuesday, and investors may react positively to the tariff news.

“Consumption remained robust during the holiday, which will boost market sentiment via the consumer sector,” said Shen Meng, director of investment bank Chanson & Co. in Beijing. “Some export-oriented enterprises will also strike an upbeat note, buoyed by the short-term tariff ruling and Trump’s visit to China.”

Trump can rely on Sections 301, 232 and 122 of the Trade Act to push forward his tariff regime, said Wendy Cutler, senior vice president at the Asia Society Policy Institute and a former acting deputy US Trade Representative. The 15% global rate Trump has set falls under Section 122. The other two powers permit the president to unilaterally impose tariffs but only following investigations that typically last months.

China is still facing a Section 301 investigation on its compliance with the Phase One trade agreement from Trump’s first term, when Beijing failed to meet purchase agreements. That investigation could be a “major feature of the back-up plan for Beijing,” Cutler said.

Additionally, Trump could expand the use of export controls if China restricts rare earth magnets. Beijing’s agreement to restore flows of the vital materials came after the US cut off sales of chip design software, jet engines and spare airplane parts.

China is likely to honor the current bilateral trade consensus rather than fore the US to make immediate corrections, said Shen Dingli, an international relations scholar in Shanghai. “Officials are likely to keep a low profile to ensure Donald Trump’s visit to China in April goes smoothly,” Shen said.

While the Chinese side may have more room to bargain, Trump has threatened new tariffs to gain leverage ahead of key meetings, and did so before his last summit with Xi in October. Though it didn’t manifest, his initial threat of an additional 100% tariff on China roiled equity markets and commodities.

The Supreme Court ruling won’t result in a fundamental reversal of China‑US economic and trade relations, said Zhou Mi, a senior researcher at a think tank affiliated with the Chinese Ministry of Commerce.

“Of course, such a ruling does not prevent the Trump administration from using other forms of executive authority to achieve its trade and other policy goals,” said Zhou. Still, “this serves as a reminder to all countries that executive power cannot, under any circumstances, be exercised beyond its originally authorized scope.”

National Security

Even as the White House looks to reconstitute the levies in another form, the court’s removal of the 10% fentanyl tariff along with the so-called “reciprocal” duties gets rid of a key sticking point between the nations. They have begun to peel back national-security restrictions in rounds of talks last year, reaching a deal over TikTok’s operations in the US as the Trump administration green-lighted the sale of Nvidia Corp.’s H200 chips, a more advanced version than previously allowed.

In the run-up to the Trump-Xi talks, Ford Motor Co.’s top executive spoke to senior Trump administration officials about a potential framework in which Chinese automakers could build cars in America while offering some protection for domestic companies, Bloomberg reported earlier this month. While such a move is likely to face congressional opposition as the mid-term elections approach, any agreement to allow more Chinese investment in the US would mark a significant breakthrough on a sensitive topic.

Chinese exporters may choose to expedite shipments to the US while tariffs are low, said Zhiwei Zhang, chief economist at Pinpoint Asset Management. “The US administration will likely seek alternative ways to keep tariffs on imports from China high,” he added. “But searching and implementing such alternative tariffs may take time.”

Zheng Tao, a Chinese export trader of car parts with more than 70% revenue from US companies, said while the ruling is “good news” and will spur more orders, he’s uncertain if there’s more bargaining power on prices after he lowered them last year to retain American clients.

Others viewed the Supreme Court’s decision as the latest stir in a year of policy ambiguity and tumult.

Lin Qian, who runs factories making toys mainly for American clients in the southern China boomtown of Shenzhen and Vietnam, was indifferent to the Supreme Court ruling. He said the constant change in policies is confusing to businessmen. While his China plants are still processing the bulk of orders, he had boosted production in his new Vietnamese factory last September as Sino-US tensions linger.

“We have to have Plan A, B, C for such dynamic conditions,” he said.
