First, and perhaps above all, the revolutions of 1989 and the subsequent collapse of the Soviet Union put an end to global bipolarity. By contrast, 2009 is likely to pave the way to a new form of bipolarity, but with China substituting for the Soviet Union.
当然，现在的情况和1989年的情况明显不同了。首先，也许是最重要的，1989年的革命和随后的苏联解体结束了全球的两极化。与此相反，2009年很可能会为一种新的两极化形式铺平道路，只是中国取代了苏联。
