海军舰艇被称为“流动的国土”,在世界各国国家中,海军是唯一可以在和平时期走出国门,进行国际间友好访问的军种。海军的这一特性,使它在担负起保卫国家领海的作战任务以外,又常常担负起国家的外交使命。近些年来,随着我国国际地位的不断提高,在军事领域中对外交往的日益扩大, Navy ships are called “floating territory.” Among the countries in the world, the Navy is the only one that can go abroad for peace and conduct friendly international visits. This characteristic of the Navy, in addition to taking on the task of defending the territorial waters of the country, often carries the diplomatic mission of the country. In recent years, with the continuous improvement of China’s international status, its foreign exchanges in the military field have been expanding day by day.
