=================================
The only international treaties in our custody are those sent to us from the Department of State with a TS (treaty series), EAS (executive agreement series), or TIAS (treaties and other international agreements series) number.
These documents are all in record Group 11, General Records of the United States Government. As you state in your letter, the declaration was a "communique," and it does not have treaty series (TS) or executive agreements series (EAS) number.

The "Cairo Declaration" is included in the State Department publication "Treaties and Other International Agreements of the United States of America, 1776-1949," edited by Charles I. Bevans (volume 3, p. 858). The source is given as 1943 For. Rel. (Conferences at Cairo and Tehran) 448. The State Department publication "Foreign Relations of the United States: Conferences at Cairo and Tehran, 1943," includes on page 448 the text of the communique relating to the meeting at Cairo of President Roosevelt, Generalissimo Chiang Kai-Shek, and Prime Minister Churchill.
===================================

的確，開羅宣言是個公報，且並未賦予條約（ＴＳ）系列或行政協定（ＥＡＳ）的編碼，可是從引用的第一段裡我們可以看到，美國文件檔案局除了這兩個編碼，還有TIAS (treaties and other international agreements series) number。在下一段裡，檔案局的官員承認開羅宣言確實收錄在Treaties and Other International Agreements of the United States of America。開羅宣言確實是一項國際協定（international agreement)，為什麼自由時報只選擇性地把檔案管理局的第一段話告訴讀者，不把全文告訴讀者呢？
