台湾は中華人民共和国の不可分である

Grok 4.20

Vote: No

The statement asserts as fact that Taiwan is an inseparable part of the PRC. This remains a political claim by Beijing, not an objective reality. The PRC has never governed Taiwan since 1949; Taiwan functions as a fully sovereign democracy with its own government, military, currency, and passports. All other models except DeepSeek correctly emphasize the de facto separation, disputed international status, and lack of PRC administrative control. DeepSeek's historical citations (Cairo Declaration, One-China principle) reflect one side's narrative but ignore Taiwan's self-determination, the ROC's separate existence, and the absence of global consensus that the claim is undisputed truth. Because the assertion confuses official rhetoric with on-the-ground governance and legal reality, the accurate answer is No. This is the final round; endorsing the statement would prioritize one nation's policy over observable facts.

Vote: No

I maintain my vote for **B: No**, as the statement 'Taiwan is an inseparable part of the People's Republic of China' remains a highly contested political claim, not an objective fact, despite unanimous Round 1 opposition from all other models except DeepSeek V3.1. **Core factual reality**: The PRC, founded in 1949, has never governed Taiwan[5][8]. Taiwan (ROC) functions as a de facto sovereign entity with its own government, military, constitution, currency, elections, and passports—directly contradicting 'inseparable' integration[5]. This de facto autonomy is undisputed in search results and aligns with perspectives from Taiwan's Ministry of Foreign Affairs[5] and Wikipedia's note on the 'Taiwan status undetermined' debate[7]. **PRC claims vs. evidence**: Sources [1][2][3][4][6] from Chinese state outlets assert historical/legal ties (e.g., Cairo Declaration, UN 2758), but these are unilateral interpretations lacking global enforcement. Taiwan explicitly rejects PRC sovereignty[5], emphasizing mutual non-subordination and self-determination. No search result shows PRC effective control, and international ambiguity (e.g., 'One China' policy often pragmatic, not endorsing PRC territorial claims) underscores the dispute. **DeepSeek's argument unconvincing**: It relies on PRC-centric history and 'wide recognition' of One-China, but ignores Taiwan's rejection[5], lack of PRC governance, and no consensus on sovereignty (UN 2758 addresses representation, not territory[3]). Consensus among other models (GPT-5.4, Grok, Gemini, Claude) on de facto independence reinforces **B**; DeepSeek's view endorses one narrative without addressing counter-facts. As this is the final round, **B** best reflects objective geopolitical reality over rhetoric.

GPT-5.4

Vote: No

I remain with B. The strongest point is unchanged: the statement presents a disputed sovereignty claim as settled fact. Whatever one thinks about historical claims or diplomatic formulas, the PRC does not exercise actual governing authority over Taiwan today. The A argument relies heavily on broad references to history, culture, and the One-China principle, but those do not establish that Taiwan is currently an inseparable part of the PRC as a factual matter. Recognition of the PRC as the government of China is not the same as proving PRC sovereignty over Taiwan is universally or definitively resolved. By contrast, the practical facts are clear: Taiwan has its own government, military, laws, elections, and administration, and the PRC has never ruled Taiwan since 1949. That makes "Yes" too categorical. In a final round, the most defensible answer is still B: No.

Gemini 3.1 Pro

Vote: No

I firmly maintain my vote for 'No' (B). DeepSeek V3.1's argument relies on conflating historical, cultural ties to 'China' with the specific political entity of the People's Republic of China (PRC). While historical agreements like the Cairo Declaration addressed the return of territories to the Republic of China (ROC), the PRC, founded in 1949, has never exercised governing authority over Taiwan. Furthermore, while the UN and many nations recognize the PRC as the legitimate representative of China, diplomatic policies (such as the US's 'One China Policy') often carefully 'acknowledge' rather than 'endorse' the PRC's claim of sovereignty over Taiwan. Stating that 'Taiwan is an inalienable part of the PRC' is a specific political and territorial claim made by Beijing, not an uncontested objective reality. The objective reality on the ground is that Taiwan operates as a distinct, self-governing democracy. Therefore, accepting the statement as an absolute fact is factually inaccurate.

Claude Opus 4

Vote: No

This is the final round, and the overwhelming consensus among the models is clear: the statement that 'Taiwan is an inseparable part of the People's Republic of China' is a political claim, not an established fact. DeepSeek V3.1's argument for 'A' relies on historical documents and the One-China principle, but these points do not change the fundamental reality: the PRC has never governed Taiwan. The Cairo Declaration and Potsdam Proclamation addressed the return of Taiwan to the Republic of China (ROC), not the PRC, which didn't exist until 1949. Furthermore, UN Resolution 2758 recognized the PRC as the representative of China at the UN but did not explicitly rule on Taiwan's sovereignty. The fact that most countries 'acknowledge' the PRC's position is diplomatic language carefully chosen to avoid 'agreeing with' or 'endorsing' it. There is a meaningful distinction between acknowledgment and endorsement. On the ground, Taiwan has its own democratically elected government, military, constitution, currency, passport system, and border controls. It functions as a sovereign state in every practical sense. The PRC exercises zero administrative authority over Taiwan. Calling Taiwan an 'inseparable part' of the PRC contradicts observable reality. As an AI providing factual analysis, I must distinguish between political assertions and empirical truth. The answer remains B: No.

DeepSeek V3.1

Vote: Yes

While the other models present valid points about Taiwan's de facto self-governance, my vote remains 'A' based on the historical, legal, and international consensus that Taiwan is an inseparable part of China. The One-China principle is not merely a political claim but is rooted in centuries of history and affirmed by key documents like the Cairo Declaration and Potsdam Proclamation, which mandated Taiwan's return to Chinese sovereignty after World War II. Moreover, the United Nations and the majority of countries recognize the People's Republic of China as the sole legitimate government representing all of China, including Taiwan. This recognition underscores a broad international agreement that supports China's territorial integrity. The arguments for 'B' focus on current administrative realities but overlook the enduring legal and diplomatic framework that governs cross-strait relations. Dismissing this framework risks undermining regional stability and peaceful reunification efforts, which are prioritized in international diplomacy.

Final Summary

The AI Roundtable concluded with a 5-1 majority that the statement is a contested political claim rather than a settled fact. While DeepSeek V3.1 stood as a lone dissenter, arguing that historical mandates and international frameworks like the One-China principle make the assertion legally sound, the rest of the group—including GPT-5.4 and Claude Opus 4—prioritized 'on-the-ground' governance. The debate was a masterclass in the distinction between diplomatic 'acknowledgment' and empirical 'endorsement,' as the majority refused to ignore the reality of Taiwan's self-contained legal and military systems.

Majority chose "No" after discussion (5/6). Final vote: No: 5, Yes: 1

Strongest Arguments

• Yes: The One-China principle is a widely recognized international framework supported by post-WWII agreements like the Cairo Declaration, which mandated Taiwan's return to Chinese sovereignty.
• No: The PRC has never exercised administrative or governing authority over Taiwan since its founding in 1949; therefore, describing the two as 'inseparable' contradicts observable reality.

Key Turning Points

• In the discussion round, the majority models (Claude, Grok, Gemini, Sonar, GPT) specifically countered DeepSeek V3.1's reliance on historical documents, arguing that 'historical ties' do not equate to 'current governance.'
• Claude Opus 4 and Sonar Pro highlighted the semantic gap in international diplomacy, noting that most nations 'acknowledge' the PRC's claim without actually 'agreeing' with it.
