The Beijing Bargain: Trump Heads to Xi Summit Armed with Grievances on Iran and Russia — But Lacking Leverage

President Donald Trump lands in Beijing on May 14 for a two-day summit with Chinese President Xi Jinping that the White House has billed as "strategically important" for reshaping the world's most consequential bilateral relationship [1]. Iran, Russia, trade, Taiwan, artificial intelligence, and fentanyl are all on the table. But the headline confrontation — Trump pressing Xi to cut material support for Moscow's war machine and Tehran's oil-funded defiance — will test whether personal diplomacy between two leaders can accomplish what sanctions, tariffs, and years of warnings have not.

The summit was originally scheduled for March but postponed after the U.S. and Israeli strikes on Iran disrupted the diplomatic calendar [2]. Its rescheduling comes as the U.S. Navy blockades the Strait of Hormuz, intercepting tankers carrying Iranian crude to China — a direct physical manifestation of the tensions Trump says he wants to resolve through negotiation [3].

What China Has Sent Russia — and What the Numbers Show

Since Russia's full-scale invasion of Ukraine in February 2022, China has become the single largest supplier of dual-use goods sustaining Russia's defense industrial base. A November 2025 report by the U.S.-China Economic and Security Review Commission (USCC) found that China remains the primary enabler of sanctions evasion in support of Russia's war effort [4]. Between June 2022 and January 2025, the Treasury and State Departments designated multiple Chinese-based entities involved in supplying computer numerical control machines, electro-optical equipment, radar components, and semiconductor manufacturing parts to sanctioned Russian companies [5].

The trade relationship has swelled accordingly. China-Russia bilateral trade hit $268 billion in 2025, up from $107.8 billion in 2020 — a 149% increase in five years [4].

In October 2024, Treasury sanctioned 275 individuals and entities across 17 jurisdictions, including China, for supplying Russia with advanced technology [6]. One designated firm, Shanghai Techinital Materials Co Ltd, had made dozens of shipments to already-sanctioned Russian companies and maintained open contracts with them [4]. Beyond direct transfers, Bloomberg reported in July 2025 on a potential joint venture between Chinese drone maker Autel Robotics and sanctioned Russian drone company Aero-HIT to localize production inside Russia, effectively circumventing export restrictions [4].

U.S. intelligence assessments have concluded that approximately 90% of "high-priority" dual-use goods used in Russian weapons production were imported from China in 2023 [7]. The financial plumbing has evolved alongside the goods: Russian and Chinese officials have been establishing regional clearing platforms to process cross-border payments for sensitive items outside Western financial channels [4].

China and Iran: From JCPOA Buyer to Sanctions-Evasion Superstructure

The Iran dimension of the summit may be even more fraught. China now purchases approximately 90% of Iran's oil exports [8]. In 2025, that meant 1.38 million barrels per day; by early 2026, Iranian exports to China hit a record 1.83 million barrels per day, representing a dramatic escalation from the JCPOA era, when China bought roughly 0.62-0.70 million barrels per day from Iran [9].

The scale of the increase matters for understanding Beijing's role. During the Obama-era nuclear negotiations (2015-2017), China was one of several Iranian oil customers — Japan, India, South Korea, Turkey, and European states all imported Iranian crude [10]. China's share was roughly 22% of Iran's exports in 2012. Today, with virtually every other buyer gone, China is Iran's economic lifeline.

The infrastructure supporting this trade has grown correspondingly sophisticated. So-called "teapot refineries" — small, independent Chinese oil companies operating with Beijing's tacit permission — process sanctioned Iranian crude into gasoline, diesel, and petrochemicals [8]. A shadow fleet of aging tankers ferries oil from Iranian ports, switching off tracking devices and conducting ship-to-ship transfers to obscure cargo origins [8]. Since March 2025, the Treasury Department's Office of Foreign Assets Control (OFAC) has designated multiple teapot refineries that collectively processed billions of dollars' worth of Iranian-origin oil [11].

Most striking is the payment architecture. The Wall Street Journal uncovered a covert system funneling an estimated $8.4 billion in oil payments from Beijing to Tehran in 2024 through Sinosure, China's state-owned export credit insurer, and an opaque financial conduit called Chuxin — absent from China's own registry of licensed banks [8]. Chinese buyers deposit payments with Chuxin, which transfers funds to Chinese contractors working on Iranian infrastructure projects insured by Sinosure, effectively creating a closed loop that bypasses the U.S.-led financial system.

In a direct challenge to Washington ahead of the summit, China's Commerce Ministry issued a directive invoking a 2021 "blocking statute" that prohibits Chinese firms from complying with U.S. sanctions on Iranian oil that Beijing deems illegitimate [12].

The Track Record: Four Summits, Few Lasting Results

This will be the sixth face-to-face meeting between Trump and Xi. The history of prior encounters suggests caution about what any single summit can deliver.

Mar-a-Lago, April 2017: The two leaders announced a cabinet-level U.S.-China Comprehensive Dialogue with four pillars covering diplomacy, economics, law enforcement, and cultural exchange. By the end of 2018, three of the four dialogues had met only once, and all were overtaken by the trade war Trump launched that year [13].

G20 Buenos Aires, December 2018: Trump and Xi agreed to a 90-day pause in tariff escalation. The pause held, but the broader deal it was supposed to produce took another 13 months of contentious negotiation.

G20 Osaka, June 2019: Trump declared Xi had agreed to resume purchases of American agricultural products, but the scope and volume were never defined [14]. A trade truce was announced; within weeks, Trump imposed new tariffs, and the truce collapsed.

APEC South Korea, October 2025: After five phone calls and five working-level meetings, the two sides reached an agreement in which Washington suspended 24% in tariffs for one year and China suspended rare earth export restrictions for a corresponding period [15]. Two-thirds of surveyed experts said China "played its hand well" on the rare earth front [16].

Biden-Xi, San Francisco APEC, November 2023 (for comparison): The most concrete deliverables — a reopened military-to-military hotline and fentanyl precursor cooperation — were modest but verifiable [17]. However, fentanyl flows continued, and military communications remained sporadic.

The pattern is consistent: summits produce announcements, but binding follow-through is rare. Agricultural purchase commitments went unmet. Dialogue architectures collapsed. Tariff truces were short-lived. The question for Beijing this week is whether this summit can break that cycle.

Economic Leverage: Who Needs Whom More?

The tariff backdrop shapes the negotiating dynamics. All Chinese goods entering the United States currently face a 54% average tariff, up from 3.1% when Trump took office in 2017 [18]. China's retaliatory tariff stands at 34% on American imports. The Tax Foundation estimates the tariff regime costs the average U.S. household $1,500 annually in 2026 [18].

U.S. industries most exposed to summit failure include automotive manufacturing — nearly 6.5% of U.S. manufacturing workers are employed in just-in-time automotive supply chains dependent on Chinese inputs [16]. Federal Reserve economists have found a net decrease in manufacturing employment due to tariffs, with the costs of rising input prices and retaliatory measures outweighing any benefits from protected industries [18].

On the Chinese side, most retaliation has been non-tariff, since the bilateral trade imbalance means China has few remaining U.S. products to effectively tariff [16]. Instead, Beijing has used canceled orders, market restrictions, and export controls on rare earths and critical minerals. This asymmetry — the U.S. has more tariff surface area to exploit, but China controls inputs American industry cannot easily replace — means neither side holds a decisive advantage.

The Steelman Case for China's Position

Not all analysts view China's support for Russia and Iran as purely destabilizing. Putin and Xi stated in January 2025 that their countries "objectively play a major stabilising role in international affairs" [19]. While self-serving, the claim reflects a strand of realist international relations thinking.

The argument runs roughly as follows: China's economic relationship with Russia gives Beijing influence over Moscow's behavior. If the United States successfully pressured China to sever ties with Russia, Moscow would become more isolated, more desperate, and more likely to escalate — including nuclear escalation. Maintaining the relationship, in this view, gives Beijing a moderating channel that would disappear under maximum pressure.

The Quincy Institute and other restraint-oriented think tanks have argued more broadly that U.S. strategy should account for the risks of driving the China-Russia partnership deeper by treating it as an axis to be confronted rather than a relationship to be managed [20]. A Council on Foreign Relations task force report characterized the partnership as presenting real dangers but cautioned that "the United States must be careful that its actions do not inadvertently deepen Sino-Russian cooperation" [21].

On Iran specifically, Beijing argues that its oil purchases prevent a humanitarian catastrophe and that maintaining economic ties preserves diplomatic channels. Critics counter that China's purchases directly fund Iran's military capacity and that the shadow payment infrastructure demonstrates intent to evade, not just engage.

Red Lines: What China Won't Do — and How Close It Is

The United States has publicly stated that Chinese lethal weapons transfers to Russia would constitute a "red line" [22]. CIA Director William Burns confirmed that as of 2023, China had "not yet made the decision" to transfer lethal aid to Russia, though the fact that Xi was considering it represented a significant shift from earlier assessments [23]. European leaders have issued parallel warnings that military aid would trigger severe consequences for EU-China relations [22].

China appears to have calibrated its support to stay just below this threshold. The Atlantic Council characterized the situation in 2024: "China's support may not be 'lethal aid,' but it's vital to Russia's aggression in Ukraine" [7]. Dual-use goods — machine tools, microchips, drone components — sustain Russian weapons production without technically constituting weapons transfers. This distinction has allowed Beijing to maintain plausible deniability while providing material that is functionally indispensable to Russia's military.

Whether China has crossed analogous red lines with Iran is murkier. U.S. officials have noted the possibility of drone parts, air defense equipment, and missile component transfers to Tehran [1], but public intelligence assessments on this front are less detailed than those regarding Russia.

The Third-Country Problem: Why Bilateral Deals Have Structural Limits

Even if Trump and Xi reach an agreement, enforcement faces a fundamental obstacle: the proliferation of intermediaries. The EU's 19th sanctions package in October 2025 targeted 45 entities, including 17 in third countries — 12 in China (including Hong Kong), 3 in India, and 2 in Thailand [24]. An earlier February 2025 package designated 34 companies outside Russia: 25 in China and Hong Kong, with others in India, Kazakhstan, the UAE, Uzbekistan, Turkey, and Singapore [25].

Eight banks and oil traders in Tajikistan, Kyrgyzstan, the UAE, and Hong Kong have been subjected to EU transaction bans for circumventing sanctions [24]. Hong Kong and Shenzhen-based firms like Woeroon Electronic Sourcing Ltd. were identified as among the most serious violators in 2026 [25].

This enforcement record reveals a structural problem: even if Xi commits to restricting transfers at the top, the network of shell companies, transshipment hubs, and alternative payment channels operating across multiple jurisdictions can adapt faster than any bilateral agreement can contain them. The regional clearing platforms being established between Russia and China [4] are specifically designed to operate beyond the reach of Western sanctions infrastructure.

The Enforcement Gap: Can Any Agreement Stick?

Arms-control lawyers and verification experts are skeptical that a summit communiqué or side deal on Iran or Russia could produce binding commitments. China has historically resisted intrusive verification mechanisms. At the February 2026 REAIM Summit in Spain, both the United States and China refused to sign a joint declaration on governing AI in military applications [26] — a signal that neither side is willing to accept constraints with teeth, even in emerging domains.

The UN Security Council offers one enforcement pathway, but China holds a veto, making binding resolutions against its own interests functionally impossible [27]. Unilateral U.S. sanctions have proven more effective at imposing costs but cannot compel Chinese compliance — only raise its price.

China's November 2025 Arms Control White Paper states that Beijing "strictly fulfills its international obligations and commitments" [27], but the U.S. State Department has publicly disputed this characterization, arguing that China's actions do not match its rhetoric on arms control and disarmament [28].

Without an agreed verification mechanism, any commitment Xi makes in Beijing would rely entirely on voluntary compliance and the threat of future sanctions — the same dynamic that has governed every prior agreement, with the results described above.

What to Watch This Week

The summit's outcome will likely be measured not by a single dramatic announcement but by several indicators:

• Language on Iran: Whether any joint statement addresses China's oil purchases or the shadow payment infrastructure, or whether Iran is relegated to vague calls for "stability."
• Dual-use goods commitments: Whether Xi offers specific restrictions on categories of goods flowing to Russia, or whether the discussion remains at the level of principles.
• Tariff concessions: Whether Trump offers tariff relief in exchange for security commitments, linking trade and geopolitics in a way that would represent a departure from prior negotiations.
• Enforcement specifics: Whether any agreement includes monitoring, reporting, or review mechanisms — or whether commitments are purely aspirational.

The White House has signaled that agreements on aerospace, agriculture, and energy are expected, along with continued work on the U.S.-China Board of Trade and Board of Investment [1]. These commercial deliverables may be the summit's real product, with the Iran and Russia confrontation serving more as a demonstration of Trump's willingness to raise the issues than as a negotiation likely to produce immediate results.

The fundamental tension remains: the United States wants China to curtail relationships that Beijing views as strategically essential. No amount of personal chemistry between two leaders has resolved that tension before. Whether this summit is different depends on whether the costs Trump can impose — through tariffs, secondary sanctions, and naval interdiction — have finally exceeded what Xi is willing to pay.
