New Delhi (ABC Live): The next major confrontation between the United States and China may not begin with missiles.
Instead, it may begin with banks, insurers, shipping documents, chip export controls, oil tankers, ports, payment systems, and legal notices.
Taiwan is usually discussed as a military flashpoint.
However, for Beijing, Taiwan is also a sanctions scenario.
China has watched the Western response to Russia after Ukraine very carefully.
It saw how quickly the United States and its allies could freeze assets, restrict banks, pressure multinational companies, block technology access, and weaponise financial networks.
Therefore, China’s central question is no longer only whether sanctions may come after a Taiwan crisis.
The real question is whether Beijing can survive, delay, dilute, and politically counter those sanctions when they arrive.
Why the May 2, 2026 Order Matters This is where the May 2, 2026 blocking order becomes important.
On that day, China’s Ministry of Commerce issued an injunction to block US sanctions against five Chinese oil refineries accused of buying Iranian oil.
The named entities included Hengli Petrochemical (Dalian) Refinery and four independent “teapot” refiners: Shandong Jincheng Petrochemical Group, Hebei Xinhai Chemical Group, Shouguang Luqing Petrochemical, and Shandong Shengxing Chemical.
At first glance, the dispute looked limited.
It involved Iranian crude, five refineries, and US secondary sanctions.
Yet, the strategic meaning was much larger.
China was not merely defending five refiners.
Rather, it was testing whether Chinese domestic law could act as a shield against American sanctions power.
The May 2 order as the moment when China’s dormant 2021 blocking statute “woke up.” In simple terms, Beijing used Iran as a rehearsal.
Meanwhile, Taiwan may become the real examination.
The Real Power Behind US Sanctions For decades, US sanctions power has rested on one simple fact: most global finance, trade settlement, marine insurance, shipping, and corporate risk management still touch the US dollar system.
As a result, even non-American firms often obey US sanctions because they fear losing access to dollar clearing, US markets, correspondent banking, or Western financial networks.
This is the practical strength of American “long-arm jurisdiction.” It does not need to control every country directly.
Instead, it controls the routes through which money, goods, insurance, and risk move.
Therefore, China is trying to make sanctions slower, more expensive, less automatic, and legally risky for companies that operate inside China.
China’s Counter-Sanctions Strategy China cannot replace the dollar system in one stroke.
Moreover, it cannot fully protect every Chinese bank, shipping firm, technology company, or energy importer from Western sanctions.
Nevertheless, Beijing is building a layered defence.
First, it is building a legal shield through blocking rules and counter-sanctions laws.
Second, it is building financial buffers through foreign exchange reserves, RMB settlement, and alternative payment channels.
Third, it is building energy cushions through crude stockpiles and sanctions-risk oil routes.
Finally, it is using China’s manufacturing centrality as leverage, because China is far more embedded in global trade than Russia was.
Therefore, the May 2 order should not be read as a narrow Iran-oil dispute.
It was a controlled test of the tools China may deploy if Taiwan becomes the trigger for a larger sanctions war.
Why China’s 2021 Blocking Rules Matter China issued the Rules on Counteracting Unjustified Extraterritorial Application of Foreign Legislation and Other Measures in January 2021.
These rules apply when foreign legislation or measures unjustifiably restrict Chinese citizens, legal persons, or organisations from conducting normal economic and trade activities with a third state or region.
In simple words, China says: If a foreign country tries to force Chinese companies to obey its sanctions outside that foreign country’s own territory, China can block that pressure through Chinese law.
Consequently, the 2021 rules are not just legal paperwork.
They are part of China’s preparation for a future sanctions confrontation.
Table 1: China’s Counter-Sanctions Architecture What the table shows: China is not building one single anti-sanctions weapon.
Instead, it is building a system.
The legal layer creates resistance.
The financial layer creates alternatives.
The energy layer buys time.
At the same time, the trade layer raises the cost for any coalition trying to isolate China.
May 2, 2026: The First Serious Test On May 2, 2026, China blocked US sanctions against five Chinese refiners.
Reuters reported that China’s Ministry of Commerce issued an injunction prohibiting Chinese entities from recognising or complying with those US sanctions.
Importantly, the order came less than two weeks before Trump’s Beijing visit, which made the timing strategically sensitive.
The US Treasury had sanctioned Hengli Petrochemical (Dalian) Refinery on April 24, 2026, alleging that it purchased Iranian petroleum through an oil terminal controlled by Iran’s Revolutionary Guard Corps-Qods Force.
Treasury also issued a wind-down licence for transactions involving Hengli.
Therefore, Beijing’s response was not only a legal reply.
It was also a signal that China would not accept every US secondary sanction as an unavoidable commercial fact.
Table 2: Why the May 2 Blocking Order Matters What the table shows: The refineries were not the real end point.
They were the test ground.
In effect, Beijing used a limited case to create a legal precedent.
Trump’s China Visit: Why the Order Became Summit Leverage The timing of China’s May 2 order was not accidental.
It came just before President Donald Trump’s visit to Beijing and turned a sanctions dispute into a summit-level bargaining issue.
On May 15, 2026, Trump said he had discussed the sanctioned Chinese oil refiners with President Xi Jinping during his Beijing visit.
He also said he was considering whether to lift the sanctions and would decide within days.
Reuters reported that the sanctions targeted Chinese companies accused of buying Iranian oil, including Hengli Petrochemical.
Thus, China did not merely issue a legal protest.
It created pressure before the summit.
By invoking its blocking statute before Trump reached Beijing, Beijing ensured that the refinery sanctions were not treated only as a technical enforcement matter.
Instead, they became part of high-level US-China bargaining.
In simple words: China used law before diplomacy, so diplomacy had to discuss the law.
More importantly, the Trump China visit showed that China’s blocking statute can operate as a negotiating tool, not only as a domestic legal shield.
Table 3: Trump China Visit and the Sanctions Timeline What the table shows: China used the May 2 blocking order to move the issue from compliance desks and legal departments into presidential diplomacy.
Why This Strengthens the Taiwan Argument The Trump China visit strengthens the Taiwan thesis.
If China can use a blocking order over five refineries to push sanctions into summit-level discussion, then in a Taiwan crisis it may use the same model on a much larger scale.
For example, a future Taiwan-related sanctions package could target Chinese banks, chip companies, shipping networks, insurers, energy imports, state-linked assets, and US multinationals operating in China.
In response, Beijing may use blocking orders, counter-sanctions, market-access pressure, and diplomatic bargaining together.
Table 4: How China May Use Summit Leverage After Taiwan What the table shows: The May 2026 Trump-Xi exchange showed how China may convert sanctions into diplomatic bargaining.
Therefore, in a Taiwan crisis, Beijing may try to force sanctions into a wider negotiation over trade, technology, finance, and market access.
Why Taiwan Changes the Scale A Taiwan crisis would not be a normal regional crisis.
Instead, it would connect military risk with finance, semiconductors, shipping, energy, insurance, and global supply chains.
If Beijing moves militarily around Taiwan, the United States and its allies may respond with sanctions similar in ambition to the sanctions used against Russia after Ukraine.
However, China is not Russia.
China is larger, more central to global manufacturing, more deeply tied to Europe and Asia, and more important to technology supply chains.
Consequently, sanctions against China may be possible, but they would also be costly.
Table 5: Possible US Sanctions After a Taiwan Crisis What the table shows: A Taiwan sanctions package would likely be broad.
It may not target only one sector.
Instead, it could hit the full operating system of China’s external economy.

First, it has a defensive side.
