这是1979年的美国国务院美泰两国首长对话的备忘录
其中一段写着：
President: Our relations with Taiwan will be on the same basis as those
between Taiwan and Japan.
Under our agreement with Peking there will be no more official relations with
Taiwan.
You should know, however, that Taiwan’s relations with Japan have prospered
under unofficial auspices. Trade levels, for example, have tripled.
We have introduced legislation to maintain the kind of relations with Taiwan
that we have with other governments. The legislation will authorize us to
permit government guarantees of business loans. I believe that the interests
of the Taiwanese people will be protected.
意思是卡特有意将台美关系变得跟台日关系一样，
因为他们发现自从台日关系变成非官方关系后，
两边的经贸变的很繁荣，甚至有三倍的量。
