The key point of intersection of these two lines of political history is the Sino-Japanese Peace Treaty-because its signing was the moment when the Republic of China, which was founded in 1912, was recognized in an international treaty as extending its sovereignty to Taiwan and Penghu after previously being reduced by the Chinese Civil War to holding only Kinmen and Matsu.
這兩大治史工作的關鍵交會點便是《中日和約》，因為那是 1912 年成立的中華民國，以在國共內戰之後僅存的金、馬地區，加上接收台、澎為領土的主權範圍確立的時刻。
