１９０７－１９０９年，中日之间发生了关于＂间岛＂问题的严重交涉。时任东三省总督的徐世昌在交涉中起到了非常重要的作用，主要表现在选贤任能、注重情报、洞悉阴谋、全盘谋划、灵活外交等方面，有利地遏制了日人的侵略阴谋。 Between 1907 and 1909, there was a serious negotiation between China and Japan about the issue of “between-island.” Xu Shichang, then governor of the northeast provinces, played a very important role in the negotiation. It mainly hindered the Japanese invaders conspiracy in the aspects of selecting and serving as their helpers, focusing on information, consummation of plots, overall planning and flexible diplomacy.
