OP-ED: Beijing Blacklists Japan — When Rare Earths Become a Weapon of Economic Destruction

Mitsubishi and Raytheon: A Strategic Partnership at a Standstill

The Patriot program is a particularly telling example. Japan, through Mitsubishi Heavy Industries in partnership with the American company Raytheon, had developed the capacity to produce Patriot systems to ease the strain on the U.S. supply chain—which is struggling to simultaneously meet the needs of the U.S. military, fulfill commitments to Ukraine, and fulfill orders from third countries such as Poland, Germany, and Israel. This program had a dual strategic value: to strengthen Japan’s capabilities and to relieve pressure on U.S. production of a system for which global demand has skyrocketed since 2022.

With MHI Logitech and Mitsubishi Precision now on MOFCOM’s blacklist, this program faces severe uncertainty. Dual-use components that could transit through or originate from suppliers with ties to the Chinese supply chain are now subject to restrictions. It is not enough for Japanese companies themselves to be on the list: if their component suppliers have ties to affected supply chains, the ripple effect is very real.

Japan’s Evolving Doctrine

What China refers to as “remilitarization” represents, in Japanese doctrine, a historic break with Article 9 of the pacifist constitution inherited from 1947. Prime Minister Sanae Takaichi has raised Japan’s military spending to 2% of GDP and is campaigning to amend this constitutional article. Japan has acquired a long-range strike capability—the modernized Type 12 missiles—capable of striking targets 1,500 km away. This represents a doctrinal revolution for a country that had refrained from any offensive posture since World War II.

For Beijing, this development is unacceptable. An offensively armed Japan—allied with the United States and now a partner in the GCAP (alongside the United Kingdom and Italy)—represents a power constellation in the Indo-Pacific that China seeks to erode. Export controls are a way to slow this momentum without direct confrontation—economic warfare as a substitute for military warfare.

Someone needs to state clearly what China is doing: it is punishing Japan for deciding to defend itself. After decades of benefiting from Japan’s pacifism—enforced by the 1947 constitution—Beijing is discovering that Tokyo is beginning to assume its strategic responsibilities. And its response is blackmail involving rare earths. This is as strategically repugnant as it is logical from Beijing’s perspective.

January 2026: The Precedent That Foreshadowed June

The measure taken on June 29, 2026, did not come out of nowhere. In January 2026, China had already imposed similar restrictions on rare earth exports to Japan. The data that followed is telling: between January and April 2026, Chinese exports of rare earths to Japan fell by a cumulative 34%, with an 88% drop in March—the month when the restrictions were most actively enforced. This decline is unprecedented in postwar Sino-Japanese trade.

This pattern is that of an economic weapon that has been tested, refined, and then redeployed with greater precision. The June list targets more specific entities in more precise sectors. The escalation is deliberate. It signals to Tokyo—and to the Western capitals watching—that China is prepared to ramp up the pressure even further if its demands are not met.

The Ripple Effect on Japan’s Allies

China’s restrictions on Japanese rare earths have repercussions that extend beyond Japan. The Patriot program is the most visible example: delays in Japanese production are impacting the global availability of a system critical to the defense of Europe and Ukraine. More broadly, the Western defense industry’s supply chain is interconnected in ways that many policymakers have long preferred to ignore.

Since 2022, the United States, Europe, and their allies in the Indo-Pacific have been undertaking a “de-risking” effort with regard to China—notably to reduce dependence on critical components. But these efforts take time. Alternative supply chains require years of investment and validation. In the meantime, the vulnerability remains real—and China knows it.

There is a cruel irony in the fact that the democracies that need rare earths the most for their defense industries are precisely those that have invested the least in alternative sources. It was convenient to let China supply these materials. It is now a well-documented strategic vulnerability. And the measures taken in June 2026 are the most recent proof of this.

The message sent to Taiwan

It would be naive to view the measures against Japan in isolation. They are part of a particularly busy week for China’s expansionist policy: on July 1, 2026, the Law on Promoting Ethnic Unity and Progress went into effect in China, legally codifying Beijing’s right to prosecute individuals and organizations abroad who “undermine ethnic unity”—including people in Taiwan.

This two-pronged approach—economically punishing Japan for its rearmament while codifying jurisdictional claims over Taiwan—outlines a coherent strategy: to weaken regional defense capabilities while strengthening legal control over populations that Beijing considers Chinese. It is an imperial policy cloaked in the language of international trade law. And it deserves to be called what it is.

The Drone and Nuclear Sectors in the Crosshairs

Among the Japanese sectors explicitly targeted by the measures are drones, civil nuclear power, and defense research institutes. The fact that Terra Drone—a Japanese company specializing in commercial and industrial drones—appears on the watchlist indicates that Beijing is closely monitoring the development of Japan’s drone capabilities. After what drones have demonstrated in Ukraine, no serious military power can afford to ignore this sector.

The inclusion of entities linked to the civilian nuclear sector in the monitoring measures is more complex: Japan has a significant civilian nuclear program and a history of ambiguity regarding its potential capacity to develop nuclear weapons. For China, any equipment that could be used to maintain and strengthen Japan’s nuclear industry is potentially suspect. This logic isn’t entirely irrational—but applied so broadly, it amounts to blackmail against Japan’s entire advanced energy and industrial sector.

The targeting of Terra Drone—a commercial drone company—strikes me as particularly telling. It suggests that Beijing is monitoring not only Japan’s official military programs but also companies that could, one day, shift toward defense applications. This is preventive industrial surveillance. And it is a tactic that the West should be far more concerned about than it currently is.

Tokyo: Strong Protest, but Limited Options

The Japanese government’s response has been measured but firm. Cabinet Secretary Minoru Kihara called the measures “unacceptable” and demanded their revocation. But beyond diplomatic protests, Tokyo’s immediate options are limited. Japan cannot quickly replace components or materials for which China is the world’s leading supplier. Alternatives—Australia, Canada, and the United States for rare earths; Europe for certain components—exist but are still under development or lack the necessary capacity.

Since 2023, the Japan Organization for Metals and Energy Security (JOGMEC) and the Japanese government have accelerated their investments in alternative mining projects in Australia, Canada, and Africa. But these projects have development timelines of five to ten years. In the meantime, every Chinese restriction hurts—even if it simultaneously drives the diversification that Beijing is specifically seeking to delay.

The U.S. Response to Chinese Measures

The United States is watching this escalation with particular attention. The Japan-U.S. Patriot program is not an isolated Japanese defense project—it is part of the U.S. strategy to maintain robust supply chains for missile defense systems. If Chinese restrictions effectively paralyze this collaboration, it is the allies’ overall ability to defend themselves that is affected.

The Trump administration finds itself in a paradoxical position: it has pursued aggressive trade policies against China on other issues, but the matter of rare earths critical to defense touches on a structural vulnerability that tariffs cannot resolve. What is needed is massive, coordinated investment among allies to rebuild supply chains independent of China. Such a plan does not yet exist in its entirety.

I find it telling that no one in Western capitals is openly discussing an emergency plan for rare earths critical to national defense. There is talk of risk mitigation. There is some funding. But a real plan for industrial mobilization to break free from dependence on China within three to five years? I don’t see one. And this absence is an invitation for Beijing to continue as it has been.

What This Escalation Reveals About China’s Strategy

The series of export control measures against Japan—in January 2026, then June 2026, with a visible escalation in the precision of the targets—illustrates a Chinese power doctrine that deserves a name: the systematic use of economic dependencies as a substitute for military means. Beijing cannot—for now—directly oppose Japan’s rearmament by force. But it can slow it down, make it more expensive, and complicate it by cutting off the supply chains that fuel it. This is low-intensity economic warfare.

This doctrine is not new. China has used it against Australia following the call for an investigation into the origins of COVID-19, against South Korea following the deployment of THAAD missiles, and against Lithuania following the opening of a Taiwanese representative office. Each time, the process is the same: identify a dependency, use it as leverage, and present the whole thing as a legitimate national trade policy decision. And each time, the targeted democracies are slow to develop systemic responses.

What the West Must Understand

The Chinese threat is not merely military. It is economic, technological, legal, and informational—and it operates simultaneously across all these fronts. The June 29, 2026, list is an example of its economic dimension. The Ethnic Unity Law of July 1 is an example of its legal dimension. Together, they paint a picture of a power that has understood that dominance in the 21st century is not built solely on missiles and aircraft carriers, but on patents, supply chains, extraterritorial laws, and export control lists.

The West must learn to respond on these same fronts. Not by copying Chinese methods—we have values to defend—but by building robust economic alternatives, diversified supply chains, and coordinated legal frameworks among allies to counter economic coercion. That war has already begun. And for now, we are not winning it.

I’ll close this essay by posing this question: if China can paralyze the Japan-U.S. Patriot program with an export control list, what will it do if the Taiwan crisis escalates into a military crisis? The answer is perhaps the most frightening thing I can imagine. And that is precisely why diversifying strategic supply chains is not a luxury. It is an existential emergency.

What This Blacklist Reveals About the Nature of the Sino-Western Conflict

By adding 20 Japanese entities to an export control list, China is doing more than just protecting its national security interests—it is sending a signal to the entire Asia-Pacific region and the West as a whole: countries that choose to defend themselves, arm themselves, or ally with the United States will pay an economic price. This signal is not subtle. It is deliberately visible.

The question is whether the targeted democracies—Japan, Australia, Europe, and the United States—have the political resolve to stay the course on their defensive modernization despite this cost. History suggests that some will waver, that some will privately negotiate accommodating deals with Beijing, and that economic pressure will create fissures in Western solidarity. Avoiding this scenario requires a clarity of analysis and political will that we have not yet fully demonstrated.

Japan as the Outpost of a Broader Conflict

Japan is on the front lines of this conflict—geographically, economically, and strategically. Its transformation into an active defense player, its break with postwar constitutional pacifism, its participation in the GCAP with the United Kingdom and Italy, and its partnership with the United States on the Patriot system—all of this represents a reshaping of the security architecture in the Indo-Pacific that Beijing seeks to curb.

Japan’s resistance to this pressure—staying the course on rearmament, firmly protesting the export lists, and diversifying its supply sources—is therefore a test of the strength of democratic alliances in the Indo-Pacific. This test is playing out right now. And its outcome will have consequences that go far beyond the fate of the 20 entities listed on a bureaucratic list in Beijing.

I believe we systematically underestimate China’s strategic coherence. Every list, every law, every restriction is a piece of a puzzle that outlines a long-term vision: to weaken the United States’ democratic allies enough so that Chinese regional hegemony becomes irreversible without a single shot being fired. We must understand this puzzle before we become pieces of it.

Summary of an Essay on an Invisible War

China’s June 29, 2026, blacklist targeting 20 Japanese entities is just one episode among many in an economic war that China has been methodically waging for years. What sets this instance apart is the precision of its targets: specific defense programs, identified supply chains, and ripple effects documented by data from the first six months of 2026. This is not diplomatic blunder. It is strategy.

The response must be commensurate. Not in rhetoric, not in statements of outrage, but in concrete action: diversifying supply chains, coordinating with allies on dual-use export controls, and investing in alternative sources of rare earths and critical components. These actions take time. It is urgent to begin them—or to accelerate them. Because China, for its part, is not waiting.

The consistency of a threat that the West still prefers to underestimate

China is the greatest strategic threat to the West—but not the only one. Russia, Iran, and North Korea pose real and well-documented threats. But China is unique in its ability to combine economic, military, technological, and normative power into a coherent strategy to challenge the liberal international order. The Japanese blacklist is a small piece of this strategy. And small pieces, when accumulated, form large structures.

We still have the choice to understand what is happening before it is too late. The list dated June 29, 2026, is yet another opportunity to make that choice.

I do not take pleasure in writing this essay. I would prefer a world where China and Japan—two extraordinary civilizations—build together rather than threaten one another. But I live in the real world. And in this world, facing reality head-on is the primary duty of both the columnist and the citizen.
