Official CCP claim: Japanese Prime Minister Sanae Takaichi committed a “grave violation of international law” when she observed that if the People’s Republic of China were to attack Taiwan, Japan would be justified in regarding itself as also threatened and in helping the Republic of China to defend itself.
Further CCP claim: If Japan did intervene in such an event, the PRC would exercise what it calls the right of self-defense against Japan.
Two letters
Such was the gist of a November 21 letter by the PRC representative to the United Nations, Fu Cong, to the UN secretary-general.
I can’t find the full text of that letter. But on December 1, 2025, its author (shown above), wrote another letter to the UN security-general rehashing and elaborating the first, including Fu’s claim that under international law Taiwan is already a part of the PRC; and otherwise responding to the “unreasonable arguments” made against his first letter by Japan’s UN ambassador.
The Republic of China’s Ministry of Foreign Affairs had also responded to Fu’s first letter (Taipei Times, November 24, 2025).
The ministry yesterday said Fu’s letter is not only arrogant and unreasonable, but also maliciously distorts historical facts and violates Article 2, Paragraph 4 of the UN Charter, which prohibits the use of threats or force in international relations.
This is the text of the cited section of the Charter: “All Members shall refrain in their international relations from the threat or use of force against the territorial integrity or political independence of any state, or in any other manner inconsistent with the Purposes of the United Nations.”
Maintaining peace and stability in the Taiwan Strait has become a strong consensus within the international community, [the Ministry of Foreign Affairs] added.
This includes Germany’s foreign minister, who has repeatedly cited the UN Charter prohibition of the use of force in opposing its use in the Taiwan Strait, and repeatedly emphasizing the importance of peace and stability in the region, the ministry said, adding that these statements highlight the shared values of countries with similar principles, underscoring their commitment to international law and a rules-based international order….
Only Taiwan’s democratically elected government can represent the nation’s 23 million people in the international community, and in international organizations and mechanisms, it said.
“China has no right to interfere or intervene.”
The party-state’s fictions about the Republic of China and Taiwan have been facilitated by the United Nations, which expelled the ROC, a founding member, from the body in 1971 to accommodate the PRC; and by the many country governments, including the United States, that in the years since have declined to formally recognize the Republic of China.
