Given that neither Chinese foreign-policy camp believes that it will get what it wants out of cooperating with the US, both simply want America’s withdrawal to happen as soon as possible, without concern for what Afghanistan will look like afterwards. For both camps, only great-power politics matters for China’s national security, and if diplomacy cannot influence the balance of power, there is little reason to engage with an issue.
考虑到上述两大中国外交政策阵营都不相信自己能从与美国合作中得益，所以他们都单纯地希望美国尽快撤军并对撤军后的阿富汗局势漠不关心。对这两大阵营来说，只有大国政治博弈才能保障中国的国家安全，而如果外交手段无法左右势力均衡，那么也没什么理由去卷入这么一场事件。
