自1990年代末以来,两岸军事安全互信机制逐渐成为两岸关系的热门话题。但是,十多年来,这个议题至今仍缺乏实质性进展,目前基本处于止步不前状态。究其原因,不仅有岛内因素的制约,更有外部因素的干扰牵制,特别是美国从中作梗。美国对这个议题的态度是有变化的。在李登辉和陈水扁执政时代,美国比较积极,其主要目的是制约大陆对台动武,防止“台独”引发战争,以 Since the late 1990s, the cross-Strait military security and mutual trust mechanism has gradually become a hot topic of cross-Strait relations. However, over the past 10 years or so, this issue still lacks substantive progress and is basically at a standstill. The reason is not only the restriction of the island factors but also the interference of external factors, especially the United States. The attitude of the United States to this issue is changing. In the era of Lee Teng-hui and Chen Shui-bian’s administration, the United States is more active. Its main purpose is to restrict the mainland’s use of force against Taiwan and prevent the war from being triggered by “Taiwan’s independence.”
