这正是1970年代英国和丹麦脱离欧洲自由贸易联盟时所发生的状况：两国一方面与各欧洲自由贸易联盟成员国展开自贸协定谈判，一方面又与欧盟（时为欧洲经济共同体）进行谈判。
This is what happened in the 1970s after Britain and Denmark left the European Free Trade Association: Free-trade agreements were negotiated among EFTA members and between them and the EU (or the EEC as it was then known).
