paragraph_text: Third Front
  
  After the Great Leap Forward, China's leadership slowed the pace of industrialization. It invested more on in China's coastal regions and focused on the production of consumer goods. Preliminary drafts of the Third Five Year Plan contained no provision for developing large scale industry in China's interior. After an April 1964 General Staff report concluded that the concentration of China's industry in its major coastal cities made it vulnerable to attack by foreign powers, Mao argued for the development of basic industry and national defense industry in protected locations in China's interior. Although other key leaders did not initially support the idea, the 2 August 1964 Gulf of Tonkin incident increased fears of a potential invasion by the United States and crystallized support for Mao's industrialization proposal, which came to be known as the Third Front. Following the Gulf of Tonkin incident, Mao's own concerns of invasion by the United States increased. He wrote to central cadres, "A war is going to break out. I need to reconsider my actions" and pushed even harder for the creation of the Third Front.
  
  The secretive Third Front construction involved massive projects including extensive railroad infrastructure like the Chengdu–Kunming line, aerospace industry including satellite launch facilities, and steel production industry including Panzhihua Iron and Steel.
  
  Development of the Third Front slowed in 1966, but accelerated again after the Sino-Soviet border conflict at Zhenbao Island, which increased the perceived risk of Soviet Invasion. Third Front construction again decreased after United States President Richard Nixon's 1972 visit to China and the resulting rapprochement between the United States and China. When Reform and Opening up began after Mao's death, China began to gradually wind down Third Front projects. The Third Front distributed physical and human capital around the country, ultimately decreased regional disparities and created favorable conditions for later market development.
