President of the United States

Washington, DC 20500
The Honorable Fumio Kishida
Prime Minister of Japan
1-6-1 Nagata-cho, Chiyoda-ku
Tokyo 100-8968, Japan
Dear President Biden and PM Fumio Kishida:We, the undersigned members of the U.S. Congress and the Japanese Diet, write to express our sharedinterest in avoiding a violent conflict in the Taiwan Strait, which would be contrary to the national
security of both countries. A potential conflict would be disastrous, and we remain concerned that thepossibility remains unacceptably high.
Reducing the risk of a violent conflict in the Taiwan Strait is in the national security interest of the UnitedStates and Japan. Hostilities would produce grave harm to the physical, economic, and social well-beingof the people of the United States and Japan, the people of Taiwan and China, and the most vulnerable
and disadvantaged people across the world.
The United States recently enacted an Indo-Pacific Security Supplemental of $8.12 billion with all House
Democrats voting in support of this military package. A robust diplomatic approach should now
accompany this measure to prioritize easing mutual misperceptions and misunderstandings that canundermine long-standing diplomatic agreements and precipitate violent military conflicts. Ever since theestablishment of formal diplomatic relations with the People's Republic of China, the governments of theUnited States and Japan recognized that the status quo with respect to Taiwan is in the best interests of theinternational community.
For five decades, our two governments helped to maintain peace by encouraging China and Taiwan to
avoid unilateral changes to the status quo. The U.S. and Japanese governments consistently supported
diplomatic efforts that discouraged language and behavior that could lead to violent international conflictor compromise prospects for the peaceful resolution of the differences between China and Taiwan.
We urge our two governments to continue their long-standing efforts to ensure that any proposed change
to the status quo in the Taiwan Strait be mutually acceptable to all parties and that disputes not beresolved by violence or the threat of violence. We ask our respective political leaders to prioritizediplomacy, to avoid confrontational rhetoric, and to reassure all parties that the United States and Japanare not indifferent to the grave risk of violent conflict in the Taiwan Strait and will take all necessary andprudent steps to prevent it.

Sincerely,ジョセフ・バイデン大統領
岸田文雄 内閣総理大臣

私たち、日米の連邦議会議員・国会議員は、台湾海峡での武力衝突は避けられねばならないとの共通の関心を有しています。そのような衝突は両国の国家安全保障上の利益に反するものであり、一度勃発すると大惨事になりかねません。私たちは、台湾有事の可能性が依然として許容できないほど高いままであることを懸念しています。
台湾海峡での武力衝突のリスクの軽減は、アメリカ合衆国と日本の国家安全保障上の利益にかないます。敵対行為は、アメリカ合衆国と日本、中華人民共和国と台湾の人々、さらには世界中の最も弱い立場におかれた人々にとって、物理的、経済的、社会的に深刻な害悪を及ぼしかねません。
アメリカ合衆国では先日、民主党のすべての下院議員の支持を得て、81 億 2000 万ドルからなる「インド太平洋安全保障追加予算」が成立しました。であるからこそ、今、長年の外交合意を損ない軍事衝突の引き金となりうる相互の誤認・誤解の解消を促進するための力強い外交的アプローチがとられなければなりません。中華人民共和国との正式な外交関係が確立されて以来、アメリカ合衆国と日本は、中台関係における現状維持が国際社会の最善の利益にかなうと認識してきました。
この 50 年間、日米両政府は、中国と台湾双方に一方的な現状変更を避けるよう促すことにより、地域の平和維持に貢献してきました。日米政府は、国際的紛争につながる、もしくは中台間の違いを平和的に解決する道を阻みかねない両者の言動を抑制する外交努力を一貫して支援してきました。
私たちは、日米両政府に対し、台湾海峡におけるいかなる現状変更もすべての当事者の合意のもとでおこなわれ、両者の対立が武力行使あるいは武力による威嚇によって解決されることのないよう、これまでの長年の努力をさらに継続するよう強く求めます。また、日米両国の政治のリーダーが、対立を深める発言を避け、外交を優先するよう求め、そして、日米両国が台湾有事の深刻なリスクに真剣に向き合い、衝突回避のために必要なあらゆる手段を講じることを誓うよう要請します。
