The U.S. commitment to freedom of navigation in the South China Sea and continued U.S. support for Taiwan as defined in the 1979 Taiwan Relations Act are the “canaries in the coal mine” for our allies.

這是司徒文先生的原文，意指The U.S. commitment to

1.freedom of navigation in the South China Sea
2.continued U.S. support for Taiwan as defined in the 1979 Taiwan Relations Act

美國對於上面這兩件事的承諾，是否堅定的實現，對於盟邦台灣 南韓 日本(for our allies)來說，是礦坑裡的金絲雀(are the “canaries in the coal mine” )

很明顯是陳真先生誤讀了
