China's contemporary policy regarding Taiwan is anchored in an uncompromising assertion of national sovereignty, a principle that defines the island's status as a settled and non-negotiable internal matter ^{[1, 2]}. This doctrine, officially articulated as the 'One China' principle, posits that Taiwan is an inalienable part of China's territory and that its eventual reunification is an exclusively domestic affair to be resolved by the Chinese people alone ^{[3, 4]}. Consequently, any form of external interference or meddling is viewed not merely as a diplomatic slight but as a direct violation of China's territorial integrity and a challenge to its fundamental sovereignty .

While this stance applies to all foreign powers, it acquires a unique and historically charged intensity when directed at Japan and the United States ^[5]. The official Chinese position is deeply rooted in the outcome of the Second World War, which it views as having definitively settled Taiwan's belonging to China through the defeat of Japanese fascism ^[6]. This historical framing transforms any external questioning of Taiwan's status into a broader challenge to the legitimacy of the post-war global order. In particular, the legacy of Japanese military aggression on the mainland during the 20th century has created a deep-seated suspicion that informs Beijing's modern strategic calculus ^[7].

The central tension, therefore, lies not just in the geopolitical dispute over Taiwan's future but in the collision of historical narratives. China's adamant refusal to countenance Japanese involvement is underpinned by a historical memory of occupation, exploitation, and a perceived Japanese ambition for regional hegemony ^{[8, 9]}. Understanding Beijing's unyielding position requires an examination of how this historical precedent of intervention shapes and reinforces the modern doctrine that forbids any strategic return of Japan to the Taiwan question.

The doctrinal foundation of sovereignty

The People's Republic of China has constructed a rigid and consistent doctrinal framework around the Taiwan issue, leaving no room for ambiguity. Official policy firmly opposes any formulation that suggests a separation of sovereignty, including concepts such as "two Chinas," "one China, one Taiwan," or "one country, two governments" . This is presented as an unchangeable reality, with Taiwan's status as an integral part of China being a determined fact . The international community's acknowledgment of this status is often cited, linking it to the alliances and outcomes of the Second World War . From Beijing's perspective, the question is not one for debate or international mediation but is a core component of its national identity and territorial integrity .

At the heart of this doctrine is the principle that the resolution of the Taiwan question is an internal affair, a matter solely for the Chinese people to decide . This principle has been explicitly communicated in high-level diplomatic engagements, such as those with the United States in the 1970s, where the idea of separate diplomatic representations was firmly rejected as an unacceptable variation of the "one China-one Taiwan" model . Furthermore, the means of reunification—whether peaceful or non-peaceful—are also defined as a sovereign, internal decision, shielded from external judgment or interference . This position is consistently reiterated in modern communications, which emphasize that China's will, resolve, and ability to defend its sovereignty should not be underestimated .

This unwavering stance is buttressed by a narrative of national resurgence and a rejection of historical weakness. Official statements frequently contrast the China of today with that of the past, declaring that the era when foreign powers could bully and dominate the Chinese people is definitively over ^[10]. This sentiment reframes the Taiwan issue as the final step in erasing a century of foreign humiliation. In this context, the "rules-based international order" invoked by Western powers is dismissed as a "logic of gangsters" designed to legitimize foreign interference while denying China the right to defend its own sovereign interests . The doctrine is thus not merely a legal or political claim, but a powerful expression of national will rooted in historical grievance.

The specter of Japanese historical ambition

The historical memory of Japanese actions in China provides a crucial subtext to Beijing's contemporary policy. Eyewitness accounts from the early 20th century describe a Japan that maintained a formidable military hold over parts of China, with troops and machine guns positioned at strategic points to enforce its political and economic demands . This experience of military coercion has cultivated a deep-seated distrust of Japanese intentions in the region. China was seen by many, including some Western observers, as the "prey of Japan," subject to predatory economic practices such as borrowing from other nations to then lend to China on ruinous terms . This history of perceived exploitation and military dominance forms a powerful precedent that informs China's current threat assessment.

Japanese justifications for its role in China have historically varied, creating a complex and often contradictory narrative. One perspective framed Japan's actions as a paternalistic duty to "awaken" its "blood brothers" in China and Korea, positioning itself as a regional leader in a manner analogous to the United States' role in South America ^[11]. Another view presented Japan as a fair competitor simply seeking a "square deal" and an "open door" for trade ^[12]. However, these benign interpretations stood in stark contrast to the perception of a relentless "Doctrine of Maximum Pressure" ^[13] and an ambition to rule Eastern Asia, instilling its own values across the continent . This historical dichotomy between professed intentions and perceived actions fuels modern Chinese skepticism about Japan's strategic goals.

This historical backdrop directly influences how Beijing interprets modern geopolitical alignments. Efforts by Taiwanese authorities to purchase advanced weaponry and seek closer ties with the United States and Japan are not viewed as routine foreign policy maneuvers. Instead, they are seen as attempts to create a "disguised form" of military alliance aimed at resisting reunification . The historical fear of a China dominated by Japanese military power, a scenario considered plausible by observers in the past ^[14], gives these contemporary moves a particularly ominous weight. Any strategic cooperation between Taiwan and Japan is therefore interpreted through the lens of historical aggression, making it a red line for Chinese national security.

International dynamics and the rejection of external legitimacy

The role of the United States has been a central, albeit complex, factor in the cross-strait dynamic. While American diplomacy formally acknowledged that the Taiwan question was an internal Chinese matter to be resolved by the Chinese themselves , other U.S. actions have been perceived by Beijing as undermining this principle. The sale of advanced weapons and the potential inclusion of Taiwan in regional defense systems are seen as direct encouragement for separatist ambitions and a challenge to the "One China" policy . Historically, some Chinese thinkers even placed their hopes in an eventual conflict between the U.S. and Japan as a potential, if desperate, path to securing China's own sovereignty ^[15]. This reliance on great power conflict highlights the precarious position China has historically occupied.

China's staunch opposition to external interference is also fueled by a perception of a global double standard. Historical accounts note that Japanese aggression was often deemed "immoral and reprehensible," while European aggression was sometimes rationalized as a civilizing mission or the inevitable destiny of the Orient ^[16]. This inconsistency has fostered a deep distrust of foreign-led international systems and their motivations. Beijing's modern assertion that "we Chinese will decide our own affairs" is a direct rebuttal to this history, rejecting any external power's claim to moral or legal authority over what it defines as its sovereign domain .

The Taiwan issue is ultimately inseparable from the shifting balance of global power. The ongoing territorial disputes between China and Japan over islands in the East China Sea are contemporary flashpoints in a long history of rivalry ^[17]. From a broader perspective, the growing economic and political influence of Asian powers like China is expected to lead to a fundamental re-evaluation of historical narratives and international norms that were established during an era of Western dominance ^[18]. In this context, China's policy on Taiwan is not just about reclaiming territory; it is about asserting its authority to redefine the geopolitical order in East Asia, free from the constraints and interventions that have marked its past.

China's policy on Taiwan is therefore not a flexible diplomatic stance but a foundational doctrine of sovereignty, forged in the crucible of historical conflict and national humiliation. Its core tenets—that Taiwan is an inalienable part of China and its status is a purely internal affair—are presented as immutable facts, immune to external debate or intervention . This position is inextricably linked to a historical narrative that casts the Second World War as the final arbiter of Taiwan's fate and views any subsequent challenge as a dangerous form of historical revisionism .

Within this framework, the legacy of Japanese imperialism serves as a powerful and enduring justification for China's unyielding posture. The memory of military occupation, economic exploitation, and strategic encirclement makes any potential Japanese involvement in Taiwan's affairs uniquely provocative and fundamentally illegitimate from Beijing's perspective . The Taiwan question thus transcends a simple territorial dispute; it represents the final, unresolved chapter in China's century-long struggle to restore its territorial integrity and reject an era of foreign domination. The insistence that its resolution is a matter for the Chinese people alone is the ultimate expression of this hard-won, and fiercely guarded, sovereignty .
