霸权主义和强权政治都是一些大国或国家集团依靠自己政治、经济和军事的能力，在国际事务中以大压小、以强凌弱、以富欺贫，甚至不惜发动侵略战争，任意干涉他国内政、践踏他国主权和领土完整，力图建立自己的霸主地位，主导世界。

Both hegemonism and power politics are embraced by some power nations or groups of such nations that impose their political,economic and military forces on small,weak and impoverished countries in world affairs.They even risk launching an aggressive war,intervening in the internal affairs and treading on the sovereignty and territory of other nations,attempting to play a dominant role in the world as the powerful chief.
