________ refers to the situation in which a country's joining in a regional trading organization leads to the reduction of its trade with nonmember countries in favor of member countries.
最容易誤選 D (Trade Creation)，因為兩者都是 RTA 效果。關鍵動詞在「reduction of trade with nonmember countries in favor of member countries」——是「減少並轉向」，而非「新創造」，故為 Diversion 而非 Creation。C 的 Trade Exclusion 則是捏造術語。
