To meet requirements of modern international law or international situation, countries in East Asia conducted internal reforms to become a sovereign nation; however, the influences of the reforms did not remain in that country but resulted in conflicts between other neighboring countries in East Asia (the speed of self-adjustment to modern international law depends on each country).
近代国際法や国際情勢の要請によって、主権国家として生まれ変わるべく国内改革が進められたが、その影響は国内に留まるものではなく、同じ東アジアに位置する周辺諸国（近代国際法への順応速度は異なる）との関係に摩擦を呼び起こした。
