在自强与开放这对矛盾体中,自强是矛盾的主要方面,是内因.只有自身强大,才能更好地开放.反之,就不能开放或不能很好地开放.同时,开放也是不可忽视的外因条件,它能直接影响到自身的强大.回顾中国对外贸易的历史,可以使我们更清楚地认识到这一点. In self-improvement and openness, the self-improvement is the main aspect of the contradiction. It is the internal cause. Only when it is powerful can it be better opened up. Conversely, it cannot be open or cannot be opened very well. At the same time, opening up is also an external factor that cannot be ignored. Conditions, it can directly affect its own strength. Reviewing the history of China’s foreign trade can make us more aware of this point.
