US Expands Crackdown on Iran's Overseas Financial Networks, Treasury Department Documents Point to China and Hong Kong-Related Channels

The US Treasury Department has expanded its sanctions on Iran's global financial and trade networks, with multiple official documents naming Chinese mainland and Hong Kong-related companies, individuals, and financial channels. Some entities have been formally sanctioned.

The US Treasury Department is expanding its economic pressure on Iran from within the country to global financial, shipping, trade, and third-country bank networks. On August 24, the Treasury Department announced the launch of "Operation Economic Outcast," stating that it will take action against global assistants who maintain Iran's economic lifeline. The officially listed network spans multiple regions, including China, Hong Kong, the United Arab Emirates, Singapore, and Europe.

This policy has already been implemented in third-country financial institutions. On August 28, the US Treasury Department took further action against Iran's use of the UAE banking system, showing that Washington is extending financial pressure to banks and intermediary channels outside of Iran.

China and Hong Kong Networks Have Been Repeatedly Included in Treasury Department Sanctions Documents

The Chinese factor is not new to the US Treasury Department's radar.

On June 10, the Treasury Department's Office of Foreign Assets Control (OFAC) announced sanctions against nine individuals and entities, stating that they were involved in supporting the Iranian Islamic Revolutionary Guard Corps and Iran's defense and armed forces logistics department's weapons procurement activities.

The Treasury Department explicitly named individuals and companies in China and Hong Kong in the document. These included Chinese nationals, Shanghai companies, and Hong Kong companies. The Treasury Department stated that a Hong Kong company was involved in Iran's secret banking network and had attempted to facilitate payments related to weapons procurement.

It is necessary to emphasize that these are formal sanctions recognized by the US government. They mean that the relevant individuals or entities have been taken measures by the US administrative sanctions agency, but do not equate to criminal convictions by US courts.

Iran's Oil Sales to China Become a Sanctions Focus

On May 11, the US Treasury Department announced sanctions against 12 individuals and entities, stating that they helped the Iranian Islamic Revolutionary Guard Corps sell and transport oil to China.

The Treasury Department stated that the Iranian Revolutionary Guard Corps hid its role in oil transactions through front companies and transferred oil revenue to the Iranian regime. The US government believes that this revenue is used for weapons projects, proxy networks, and security agencies.

On April 28, the US Treasury Department also issued a risk warning to financial institutions, naming Chinese independent "teapot" refineries that import and process Iranian crude oil, highlighting the sanctions risks involved.

The official document stated that China purchased about 90% of Iran's oil exports, with independent refineries accounting for most of the imports. The Treasury Department reminded financial institutions to strengthen risk control and avoid assisting sanctioned refineries or related companies that may continue to import Iranian crude oil.

The importance of this warning lies in the fact that the US Treasury Department is no longer only targeting specific sanctioned companies but is also alerting the global banking system that transactions with some Chinese refining and trading channels may carry US sanctions risks.

Renminbi Settlement and Shadow Banking Enter US Investigation Scope

Another official document released by the Treasury Department on May 1 further revealed the settlement method for Iran's oil revenue.

The US Treasury Department stated that since Iran's oil sales are mainly settled in renminbi, Iranian foreign exchange exchange institutions and front companies play an important role in converting oil revenue into currencies that can be used by Iran's military, partners, and proxy networks.

OFAC therefore sanctioned related Iranian foreign exchange institutions and their affiliated front companies.

This official judgment makes the relationship between China's financial system and Iran's sanctions issue more sensitive.

Here, it is still necessary to strictly distinguish: the Treasury Department's document explains that the renminbi plays an important role in some of Iran's oil trade settlements, which does not mean that all Chinese banks or renminbi transactions are illegal. Whether the US will take action against specific Chinese financial institutions next depends on the Treasury Department's formal sanctions announcements.

Hong Kong Seen as an Important Financial and Trade Node

Multiple Treasury Department documents have repeatedly mentioned Hong Kong-registered companies.

The June sanctions document showed that Hong Kong companies were accused by the US government of participating in Iran's secret banking network and military procurement payments; other Treasury Department actions named Hong Kong shipping companies involved in transporting Iranian oil.

For example, the Treasury Department's action announced in July stated that oil tankers operated by Hong Kong companies had transported large amounts of Iranian crude oil to China, and Chinese mainland companies had managed ships transporting Iranian oil products.

This indicates that, under the US sanctions enforcement framework, Hong Kong is seen as an important external node for Iran to circumvent financial and trade restrictions.

August 24 Action Escalates Pressure to Global Financial War

On August 24, Treasury Secretary Scott Bensen stated in a formal speech that the goal of launching "Operation Economic Outcast" is to cut off Iran's economic connections globally.

He explicitly stated that the US will attack the international financial channels that support Iran's economic system and extend the scope of action to third countries.

The Treasury Department's sanctions action announced on the same day listed a network covering the UAE, Hong Kong, China, Singapore, Switzerland, and other European regions, including companies, brokers, and ships involved in Iranian oil transportation, fund transfers, military procurement, and network activities.

This means that US sanctions policy is being upgraded from targeting individual Iranian institutions to targeting the entire cross-border financial and trade ecosystem.

Whether Chinese Banks Will Be the Next Target Remains to Be Confirmed by Official Documents

Currently, US official documents have explicitly pointed to some individuals, companies, trading companies, shipping companies, and refineries in China and Hong Kong.

However, based on publicly verifiable Treasury Department materials, it cannot be claimed that the US has implemented a new round of comprehensive sanctions against Chinese large state-owned banks.

Whether the sanctions will be extended to the bank level depends on whether OFAC, FinCEN, and the US Treasury Department publish specific institution names, legal basis, and sanctions measures.

Therefore, the most accurate conclusion at this stage is: the US has extended its economic pressure on Iran to global trade, financial, and shipping networks, including China and Hong Kong; some Chinese and Hong Kong entities have been formally sanctioned, but new sanctions against Chinese large banks are currently a potential policy risk rather than a confirmed fact.

"Focus on China" will continue to track US Treasury Department, OFAC, FinCEN, and congressional public documents and verify with US government first-hand documents when specific Chinese financial institutions are formally taken measures.
