Japan Crosses China's Red Line on Taiwan | Dr. Joanna Lei

## Introduction A single phrase—“survival-threatening crisis”—has detonated a region’s fragile equilibrium. What might have been treated as a rhetorical flourish in a parliamentary exchange instead reopened wounds that span more than a century, summoned memories of occupation and mass violence, and forced a reassessment of alliances and intentions across East Asia. The exchange captured in the recent conversation with Dr. Joanna Lei makes plain that this episode is not merely a diplomatic spat: it is a test of how historical memory, domestic politics, and great-power calculations interact when the stakes include the possible use of force around Taiwan. The outcome will shape not only Tokyo–Beijing ties but also the security architecture and the social fabric of the entire Sinosphere. ## The Painful History Behind "Survival Threat" Words carry weight where history is raw, and nowhere is that more true than in East Asia. Dr. Joanna Lei underscores how the phrase “survival-threatening” is not neutral in Chinese ears. It evokes a narrative used in the lead-up to Japanese military expansion in the late nineteenth and early twentieth centuries—an argument that justified aggression and, ultimately, the massive carnage of the Sino‑Japanese War and the Second World War’s Asian theater. For millions of Chinese, the memory of cities burned, communities massacred, and entire infrastructures shattered remains vivid through family histories, public commemorations, and state narratives that tie past humiliation to present sovereignty. That historical resonance explains why the Japanese prime minister’s parliamentary formulation did more than redefine strategic ambiguity; it crossed a symbolic threshold. After 1945 Japan embedded pacifism into its postwar identity via the so-called peace constitution and Article 9. For generations across the region, those institutional restraints had signaled a break with the past. To suggest that events in the Taiwan Strait could constitute a Japanese “existential” or “survival” crisis is therefore to invite comparisons with prewar rhetoric—seen by many in China as an early warning signal for militarism reborn. As Dr. Lei notes, it is not just the content of the statement but its location—an official declaration in the Diet—that matters. When historical trauma and official language coincide, diplomatic ruptures become much harder to mend. ## Taiwan's Divided Reaction & The US Silence The response inside Taiwan is not monolithic, and the fissures matter. On one side are actors who see a clearer Japanese security commitment as a protective hedge against pressure from the mainland. Pro‑Japan, pro‑independence elements welcome language that implicitly expands the legitimate uses of military force to deter coercion. On the other side are those who fear that such alignment will erode Taiwan’s strategic autonomy and make the island a flashpoint rather than a buffer. Dr. Lei’s account highlights how leaders and constituencies in Taiwan interpret the same gesture through very different historical lenses: for some it validates a favored identity rooted in a colonial-era nostalgia; for others it recalls the risks of being perceived as a client in a larger great-power contest. Into this fraught local calculus steps a conspicuous silence from Washington. The absence of a calming or clarifying message from the United States has strategic implications. Silence can be read as tacit approval, a deliberate distancing, or mere disinterest—each interpretation generates different responses in Beijing, Taipei, and Tokyo. Dr. Lei frames that silence against a backdrop of U.S. policy evolution: the gradual normalization of Japan as a more robust military partner within the U.S.-led order. Washington’s incremental easing of constraints on Japanese capabilities and closer operational integration with Tokyo make it plausible that Beijing reads recent Japanese moves not in isolation but as part of a broader U.S.-led rebalancing. Whether or not that reading is accurate, it changes incentives. If Tokyo’s stance is perceived as implicitly backed by Washington, Beijing may feel compelled to respond more forcefully—both to deter any change in the status quo over Taiwan and to signal to its domestic audience that historical grievances will not be allowed to become contemporary subordination. ## How The Crisis Could Escalate From Here Escalation can follow many pathways, and the conversation with Dr. Lei sketches several of them. The first is rhetorical and symbolic: official protests, travel advisories, cultural measures (such as discouraging tourism), and economic moves that damage person-to-person links can harden public attitudes and reduce the political space for conciliatory diplomacy. The second is operational: increased military exercises, patrols around disputed islands, and tighter maritime enforcement regimes create more opportunities for miscalculation. The presence of U.S. forces and deeper defense cooperation with Japan would amplify these dynamics, producing higher-risk interactions at sea or in the air. A third pathway is multidirectional: concurrent disputes over the Senkaku/Diaoyu islands, the Northern Territories, and other contested maritime spaces could turn a bilateral spat into a broader regional crisis. Dr. Lei warns that Tokyo is confronting simultaneous fault lines—territorial claims with China, with South Korea, and with Russia—that could all be activated if political leadership is unwilling or unable to de-escalate. Domestic political constraints in Tokyo compound the risk. A prime minister who lacks a solid majority and whose coalition is fragile faces fierce incentives to avoid the appearance of retreat; yet persistence risks turning a single statement into a cascade of confrontations across multiple theaters. Economic and social instruments will be tested too. Travel advisories and consumer boycotts can be used selectively to inflict costs without triggering kinetic conflict, but their cumulative effect frays the soft ties that long anchored cross-border relations. Dr. Lei highlights how history is invoked to justify such measures, reminding Chinese audiences of 1895 and the subsequent half-century of Japanese rule that transformed Taiwan. When state narratives mobilize these memories, even nonmilitary pressure becomes a means of signaling resolve and defending honor. Finally, there is the risk of strategic misreading: Beijing may assume there is a coherent U.S.–Japan plan to change the status quo; Tokyo may misread Chinese restraint as weakness; Taiwanese leaders may overestimate the willingness of external powers to engage militarily. Any one of these miscalculations, compounded by domestic pressures on leaders in each polity, could accelerate a slide from diplomatic tension to dangerous brinkmanship. ## The Difficult Path to Reconciliation Reconciliation in East Asia has always been a marathon, rarely a sprint. What the conversation with Dr. Lei makes clear is that durable rapprochement requires more than transactional diplomacy; it demands an honest engagement with competing memories. Japan’s domestic understanding of wartime suffering—often cast in universalist terms as victims of war—differs markedly from Chinese and Taiwanese narratives that center Japanese responsibility for specific atrocities. This divergence is not a mere historiographical quibble: it shapes what populations will accept as apologies, memorial practices, and assurances against future aggression. Practical politics complicate the moral project. Political actors in each country draw on selective histories to legitimize present policies: nostalgia for Japanese rule can legitimize pro-Japan positions in Taiwan; fears of encirclement can legitimize assertive postures in Beijing; electoral incentives shape how leaders respond to perceived slights. Reconciliation thus requires political leaders willing to invest domestic capital in recognizing harms

Japan Crosses China's Red Line on Taiwan Japan’s brand new prime minister, just made China serious angry. During a parliamentary hearing, on November 7, Sanae Takaichi said relations to a potential Chinese blockade of Taiwan "If warships are used and other armed actions are involved, I believe this could constitute a Survival-threatening crisis". China reacted fiercly, including official protests, threats, and a travel advisory to avoid all trips to Japan. Even the Stock Markets are now reacting negatively. Here to discuss what is happening is Dr. Joanna Lei, a former Law Maker in the Republic of China (the is the government of Taiwan) and a great friend of inner Chinese peace and reconciliation.

During a parliamentary hearing on November 7th, Sanae Takeuchi said, in relation to a potential Chinese blockade of Taiwan, that if warships are used and other armed actions are involved, she believes this could constitute a survival- threatening crisis. China reacted fiercely, issuing official protests, threats, and a travel advisory to avoid all trips to Japan. Even the stock markets are now reacting negatively. Here to discuss what is happening, and why this statement is such a huge problem, is Dr. Joanna Lei, a former lawmaker in the Republic of China—that is, the government of Taiwan—and a great friend of inner-Chinese peace and reconciliation. Joanna, welcome back. #Joanna Lei Thank you, Pascal. You picked the right time for a very serious topic. #Pascal It's a very, very serious topic, actually. And I'm quite surprised by how this all blew up. Can you maybe tell us first what exactly happened, and why China is reacting the way it is? #Joanna Lei I think there are a couple of really important points. Takeuchi’s statement is her official statement as prime minister in the Diet, and it’s also the first time Japan has moved away from a kind of strategic -- 1 of 11 -- ambiguity and made a very clear declaration that what happens in Taiwan—or in the Taiwan Strait— even in a blockade situation, would constitute a survival threat for Japan. That would give Japan the right to intervene militarily. So all of these are firsts. It’s the first time ever, after the Second World War or in recent years, that something like this has happened and been made official in the Diet. So China reacted strongly. Taiwan’s DPP, the pro-independence and pro-Japan faction, reacted jubilantly. So I think there are real reasons this is not just a diplomatic hiccup, but a very serious issue. #Pascal And the thing for Japan is that the phrase “survival-threatening situation” would mean the prime minister could dispatch the Self-Defense Forces, also in collective self-defense with other allies— meaning the United States and Taiwan. China is now officially saying this is an inadmissible way of interfering in internal Chinese issues. Do you think the Chinese are overreacting, or was this to be expected? #Joanna Lei I think there are long historical wounds caused by Japanese military expansion toward China, starting from 1895 and then again from 1931 to 1945. Those wars left China—whether the Qing Dynasty or the current government—with deep scars that this simple statement has reopened. In addition, they were very careful; they told people what it meant to be considered a survival threat, because Japan has used that term in its past aggression toward China and in the Pearl Harbor situation. So once this term is used, linking the Taiwan Strait and the situation in Taiwan to Japan’s survival threat, it sends a very strong signal of potential military intervention. And that, of course, is not something we’ve heard before. That’s why the reaction is strong, swift, and decisive. #Pascal The thing that I believe isn’t clear here in Japan—and probably outside as well—is just how hurtful it is for Chinese ears to hear this phrase, “survival-threatening crisis” or “existential crisis,” because it goes back to the Second World War. Could you speak to that a bit? #Joanna Lei Actually, before the major military confrontation in the Second World War, Japan used this idea of a “survival threat” as the reason to launch military attacks against China. From that, you can understand that the Second World War—whether you count it as a 14-year period or an eight-year period—caused over 30 million casualties or deaths in China, along with massive destruction of property and infrastructure. So this has served as a real warning for Japan never to wage military aggression against other regions in the Asia-Pacific. -- 2 of 11 -- And that is exactly why, after the war, Japan adopted a quote-unquote “peace constitution,” written by the American General Command at the time. That’s also why Japan has Article 9 in this so-called peace constitution. So, with Takeshi stating this in the Diet and signaling that she is contemplating changes to other related clauses and laws regarding the military, it’s sending a signal that the militarism that once haunted Asia in Japan’s past seems to be reviving. And that revival has caused huge shockwaves in China. #Pascal One thing Takahichi hasn’t done since becoming the new prime minister is visit the Yasukuni Shrine, the war-criminal shrine. She sent flowers instead of going there, but she didn’t go herself. How do you explain that she’s now using such rhetoric in parliament? #Joanna Lei Well, certainly she has acquiesced in terms of going to the Yasukuni Shrine. We've maintained that position. Both people in the PRC and people in Taiwan, whose governments fought in the Second World War, have long insisted that those 14 Class A war criminals are the reason we reject any Japanese politicians visiting the Yasukuni Shrine. So I think Takahichi understands the severity of that, and she acquiesced. However, she has a long-term plan, both in her campaign and in her actions as prime minister, to, quote-unquote, “normalize” Japan. That is to have Japan’s Self-Defense Forces become a full military, lifting restrictions on expansion beyond the four main islands, and she’s considering reviving related laws regarding the use of nuclear-related powers. All of these are sending really strong signals that she believes she has a destiny she’s following. She may take different steps, she may sometimes acquiesce, but this new statement—especially made in the Diet—sent a very strong signal and serves as a warning to countries in the Asia-Pacific that were once occupied or militarily controlled by Japan. #Pascal One of the frustrating things about this comment was that it was made in reply to a parliamentarian from the left wing who actually pressed her on the issue and wanted her to answer in the negative. But she didn’t—she answered in the positive and made that statement. Is it also being taken into consideration that this was in reply to a question in the Diet, or is the Chinese, especially on social media, interpreting it as an intentional provocation that came out of a deliberate plan to provoke? #Joanna Lei -- 3 of 11 -- Well, I think we need to look at the sequence of events. You could interpret the original statement as a reaction—it could have been a setup, or some kind of collaboration between the two. But be that as it may, afterward there were numerous reports and situations where China asked her to perhaps retract or restate the statement, and she refused to do that. With the diplomatic pressure first exerted in both Japan and Beijing, along with the follow-on travel advisories and the new military and mission drills in nearby maritime territories, all of this indicates how serious and severe the situation might be. But there has been no retraction from her or from her party, and there seemingly has been no change in position. So perhaps the original statement was a setup, but the follow-on reactions—one after another, wave after wave—seem to indicate that she is holding steadfast to this position. #Pascal Yes, that’s certainly true, because there was no— as you said— no attempt to walk any of this back, even after it became clear how severely it was being interpreted on the other side. One more thing: a Chinese friend of mine told me that, from a Chinese point of view, this is Japan inserting itself needlessly into a problem that isn’t its own. Do you interpret it that way too? #Joanna Lei Well, certainly that indicates what may happen across the Taiwan Strait. You have to take into account what Taiwan—especially the Tsai Ing-wen government—is doing. Within Taiwan, the reaction is clearly divided: one part is extremely welcoming and celebratory, while the other is worried and feels this may cause huge problems for our relationship across the Taiwan Strait. Lai Ching-te has long taken the position that the heyday of Taiwan was during Japanese rule, and his independence proposals would in some way rely on U.S. and Japanese military support should there be a Taiwan independence movement or any proclamation or moves toward that, and should there be military aggression from the PRC. So when Takayoshi walked directly into this line, Lai Ching-te and his government, and some of the people who supported them—also taking a sort of royalist, pro-Japanese, former-colonial position—welcomed this with jubilation. So it’s not surprising that China would take this as indirect support, or maybe even explicit support, for a Taiwan independence movement or advocacy, because it was received in Taiwan exactly that way. #Pascal The situation is further complicated, in my view, by the relative silence of the United States, which isn’t trying to say, like, “please, calm it down.” The United States seems to be just, you know, letting it go. Because obviously, a worsening of relations between Tokyo and Beijing is directly in favor of Washington. How do you think the Chinese are factoring this into the response they’re giving now? -- 4 of 11 -- #Joanna Lei Well, if you go back to the origin of the “peace constitution,” and Article 9, it was precisely meant to restrain Japan from making any move, statement, or action that might push others in the Asia- Pacific toward military escalation. So now, if this has been met with such strong opposition, it’s probably natural for the PRC to expect the U.S. to make some kind of statement—but it didn’t. I think in recent years, starting from the Biden era, the United States has been gradually easing restrictions on Japanese military expansion. It’s now accepting Japan not only as a base for its most significant strategic assets, like the F-35, but also allowing Japan to join the supply chain—the military supply chain—of the overall U.S. build-out. So perhaps it’s being interpreted as Japan not acting in a vacuum. It’s acting with perhaps the implicit understanding, or even acknowledgment—or even encouragement—by the U.S., in order to present a stronger military force to rebalance power in the Pacific. Because we all know that after September 3rd, people now understand how strong the PRC’s military build-up has been, especially over the last four or five years. So perhaps dragging or pulling Japan into some kind of rebalance—just like pulling South Korea into a nuclear submarine build-up— would be in the best interest of the United States. It would strengthen its local allies without incurring greater military expenses. So all of this is factored in, and
