1997年6月20－22日在美国丹佛举行的首脑会议，具有以下两个特点：第一，俄罗斯领导人从过去几年的“编外”地位晋升为正式成员，使西方七国首脑会议变为八国首脑会议；但由于俄罗斯的经济实力悬殊，无法与其他七国平起平坐讨论经济问题。第二，会议取得成果不大的主要原因是，美欧在一系列经济政策上存在分歧，各自坚持不同的模式。 The summit held in Denver, the United States, on June 20-22, 1997, has the following two characteristics. First, the Russian leader has been promoted from an “extranodal” position in the past few years to an official member, turning the summit of the G-7 into G8 summit; but due to the disparity of economic strength of Russia, unable to talk about economic issues with other seven countries on an equal footing. Second, the main reason why the meeting did not make much success was that the United States and Europe differed on a series of economic policies and adhered to different modes.
