Under the leadership and command of the Communist Party ofChina （CPC） and Chairman Mao, the People's Liberation Army （PLA）had fought bravely for four years until May 1950 when they anni-hilated 8.07 millions of troops of Kuomintang （KMT）, NationalistParty of China, and occupied Nanjing, signifying the overturn of thereactionary dominance of KMT government lasting twenty-two years.The PLA then liberated all the rest of the Chinese territory, except theislands of Taiwan, Penghu, Jinmen, Dachen and Mazu, winning theLiberation War, which was crucial to China.
However, Chiang Kai-shek and his government, supported by theUnited States of America, were not conceding their defeat in Main-land China. Chiang Kai-shek ordered the remains of his air force toraid all the important coastal cities on the Mainland, aiming at violat-ing the construction of New China. In June 1950, taking advantage ofthe breakout of Korean War, the Americans forces invaded Taiwan, aChinese territory, and sent warplanes into our eastern coastal areas forreconnaissance. In 1953, US president Dwight D. Eisenhower tookoffice. He had a preference for the anti-communist policies of Chi-ang Kai-shek, and signed the Common Defense Treaty with Taiwan.
