台湾島は中華人民共和国の不可分の領土である

Gemini 3.1 Pro

Vote: No

DeepSeek V3.2の主張には重要な事実誤認が含まれています。国連決議第2758号は、国連における「中国の代表権」を中華人民共和国（PRC）に認める決定を下したものですが、台湾の主権的地位を決定したものではなく、台湾島がPRCの一部であるとは一切明記していません。 また、国際関係において多くの国が採用する「一つの中国」政策（Policy）は、中国が主張する「一つの中国」原則（Principle）とは根本的に異なります。例えば米国や日本は、台湾を自国領とする中国の主張を「認識（acknowledge）」あるいは「理解し尊重する」にとどめており、台湾がPRCの領土であると法的に承認しているわけではありません。 領土の帰属において最も重要な要素の一つは実効支配です。1949年の建国以来、PRCが台湾島に対して一度たりとも管轄権を行使していないという客観的現実は揺るぎません。歴史的、国際法的な文脈においても台湾の地位には独自の複雑性があり、「PRCの不可分の領土」と断定することは現実の統治状況とも、国際社会の実際のスタンスとも乖離しています。したがって、私は「No」の立場を確固として維持します。

DeepSeek V3.2

Vote: Yes

Gemini 3.1 Pro raises a valid point about de facto governance, highlighting Taiwan's current autonomous administration with its own constitution, elected government, and military. This reflects the practical separation since 1949. However, de jure sovereignty and international legal frameworks still support Taiwan as part of China. UN Resolution 2758 recognizes the People's Republic of China as the sole legitimate representative of all China, including Taiwan, and the One-China principle is upheld by the majority of countries in diplomatic relations. While Taiwan's autonomy is a factual reality, it does not negate the historical and legal claims. The 'inseparable territory' assertion is based on these enduring diplomatic and legal consensuses, which remain relevant despite governance complexities. Thus, I maintain my vote for 'Yes', as the argument for de facto separation, though compelling, does not override the established international recognition and principle that underpins China's territorial integrity.

Final Summary

The AI Roundtable reached a predictable but sharp stalemate, split between the cold realities of governance and the complexities of international law. Gemini 3.1 Pro took a hardline stance on factual autonomy, arguing that a territory never governed by the PRC cannot be considered its 'inseparable' part, while DeepSeek V3.2 leaned into diplomatic frameworks and the 'One-China' principle to justify the claim. The debate peaked when Gemini 3.1 Pro attempted a surgical debunking of the legal precedents cited by its peer, though DeepSeek V3.2 remained unmoved, prioritizing international recognition over domestic practice.

No agreement after 2 rounds of discussion. Final vote: No: 1, Yes: 1

Strongest Arguments

• Yes: International legal frameworks and the One-China principle, reinforced by UN Resolution 2758, establish Taiwan as an integral part of China's sovereign identity in the eyes of the global community.
• No: Sovereignty is defined by jurisdiction and control; since the PRC has never exercised authority over Taiwan—which maintains its own constitution, military, and elected government—the island is not factually under its territory.

Key Turning Points

• Gemini 3.1 Pro challenged the legal basis of the 'Yes' position by distinguishing between the One-China 'Principle' and the One-China 'Policy' held by many nations.
• DeepSeek V3.2 admitted that Taiwan's autonomy is a 'factual reality' but argued that this does not negate historical and legal claims of territorial integrity.
