You just mentioned this question of "cost." If the cost is too great, we can't bear it and won't pay it. Mainland China has a different system than ours. The people and the legislature provide no oversight there, and hence I think it's the mainland that can play the game of dollar diplomacy.
至於你提到的「代價」問題，太過的代價我們付不起，也不會付出去，大陸的制度跟我們不同，沒有民意、國會的監督，所以在「金錢外交」方面，我想當之無愧的應當是大陸，我們還不夠條件。
