近年来,随着中苏两国关系的改善,经济贸易交往也日益活跃起来。位于中苏边境的黑龙江省黑河市和绥芬河市,作为我国东北两个重要的口岸城市,就仿佛是中苏经济的两扇大门。透过这两扇门;可以窥见中苏经济、技术、贸易合作的现状和前景。 In recent years, as the relations between China and the Soviet Union have improved, economic and trade exchanges have become increasingly active. Heihe City and Suifenhe City in the Heilongjiang Province along the Sino-Soviet border are two important ports in Northeast China, and they seem to be the two gates of the Sino-Soviet economy. Through these two doors, you can get a glimpse of the status and prospects of economic, technological, and trade cooperation between China and the Soviet Union.
