中国是陆地大国,也是海洋大国。它有1800多公里的海岸线,6000多个岛屿,领海和专属海洋经济区面积占大陆面积1/3以上。中国资源丰富,曾深受帝国主义的宰割,历史上侵略者多来自海上。中国要立于不败之地,维护和收复海洋权益,必须建立强大的海军,有强大的核潜艇打击力量。这是中国近代史的忠告,也是毛泽东生前下大决心 China is a land power and a big marine power. It has more than 1,800 kilometers of coastline and more than 6,000 islands. Its territorial sea and exclusive marine economic zone occupy more than one third of the mainland area. China is rich in resources and once deeply invaded by imperialism. In history, most of the invaders came from the sea. To maintain its invincibility and safeguard and regain its maritime rights and interests, China must establish a strong naval force and a strong nuclear submarine strike force. This is an advice of modern history in China and a determination of Mao Zedong during his lifetime
