Two days before Donald Trump landed in Beijing, China's National Financial Regulatory Administration verbally instructed the country's largest banks to suspend new yuan-denominated loans to five Iranian-linked teapot refineries that the US Treasury had sanctioned. [1] Existing credit lines stayed in place. New financing froze. The directive arrived ahead of China's May 1 public holiday. On May 2, the Ministry of Commerce issued a public order directing Chinese firms to disregard the same US sanctions. Defiance was the public layer. Quiet bank compliance was the layer below. The cleanest example of the split rhetoric–and–balance-sheet posture the paper has been tracking since April.

The refineries include Hengli Petrochemical (Dalian) Refinery Co., which Treasury sanctioned on April 24 under OFAC authority. [2] Hengli is one of China's largest private refiners, processing billions of dollars of Iranian crude. The same Treasury action sanctioned about forty shadow-fleet vessels. Four other teapot refiners had been previously sanctioned. On April 28, OFAC issued a sanctions alert warning financial institutions of secondary-sanctions risk in dealings with the teapots. [3] Bessent's statement at the time invoked "maximum pressure" and committed Treasury to continued action against the "network of vessels, intermediaries, and buyers" Iran uses. The pre-summit alert and the bank directive are paired instruments: the US named the risk in public; China responded operationally in private.

Hengli alone had budgeted approximately 235 billion yuan ($34.4 billion) in total banking credit for the year, per the public reporting summarizing the original Bloomberg and Reuters dispatches. [4] The freeze affects new lending, not existing facilities, but caps the refinery's expansion track. Chinese teapot refineries collectively had planned hundreds of billions of yuan in 2026 expansion projects; the NFRA action creates what one analyst summary called a "financial ceiling" that does not lift until secondary-sanctions risk eases. The economic logic is exposure protection. China's biggest banks — Industrial and Commercial Bank of China, Bank of China, China Construction Bank — process trillions of dollars annually through correspondent banking relationships that depend on US dollar clearing access. Losing dollar-clearing would cripple them. Protecting the clearing privilege required walking back the new loans.

The Commerce Ministry's parallel rhetoric is a public artifact for an audience that needs to see Beijing pushing back. Wang Yi defended Iran's right to peaceful nuclear energy at his Beijing meeting with Araghchi the previous week. [5] China criticized the US blockade of Iranian ports as not serving "the common interest of the international community." The Commerce Ministry's May 2 statute invoked a 2021 blocking rule that prohibits Chinese firms from complying with foreign sanctions Beijing deems illegitimate. The blocking statute is the public banner. The NFRA directive is the private floor. The Trump-Xi readout on Thursday's first day of summit business produced agreement that no country may charge tolls in the Strait of Hormuz — a position consistent with the bank directive's logic and inconsistent with the Commerce Ministry's blocking rhetoric. [6]

China is the buyer of more than 80% of Iran's shipped oil. Kpler's 2025 estimate puts the average at 1.38 million barrels per day. [7] The teapots account for the majority of those imports. Constraining new financing to them, without dismantling existing relationships, is the financial-system equivalent of the public posture China has held since the war began — rhetorical solidarity with Tehran, operational caution about sanctions exposure. The NFRA's verbal instruction format — guidance rather than written rule — gives Beijing plausible deniability if pressed. Beijing has not publicly acknowledged the directive. Iran International, citing the Reuters and Bloomberg reporting, has carried it. [8]

The summit's Iran paragraph adds a US-China bilateral commitment to the existing Treasury campaign. The pre-summit Wang-Rubio April phone call agreed both governments would oppose tolls in the strait. [9] The Beijing readout extended that agreement to a presidential commitment. The Iranian institutional response — the Persian Gulf Strait Authority's vetting and fee regime — runs counter to both. The bank directive answers a different question: not whether tolls are paid in the strait, but whether the refineries that buy Iranian crude can finance their next expansion. Beijing's answer this week is no, and the directive arrived without a press release.
