Christina Liu, former People First Party legislator and now chief economic advisor at the Daiwa Institute of Research, points out that "the word 'agreement' in international parlance is a very sensitive political term. It involves the 'state-to-state' issue and inevitably draws one into the 'insoluble equation' of the 'one-China' principle."
曾任親民黨立法委員的日商大和總研公司首席經濟顧問劉憶如指出，「『協定』這個字，在國際上是很敏感的政治字眼，涉及『國與國』的問題，勢必捲入『一中原則』的無解方程式。」
