Argument: Tibet is economically disadvantaged due to its altitude problems
- "Tibet: China's policy paper on Tibet". Information Office of the State Council of the People's Republic of China. May 2004 - "Since Tibet had very little to start with in terms of social development, and because of its high-altitude oxygen deficiency and other harsh natural conditions, the level of modernization in Tibet still lags far behind the coastal areas in southeast China. Tibet remains thus far an underdeveloped area in China."
