Annual Report to Congress: The Military Power of the People's Republic of China 2005 [open pdf - 1MB]
"The rapid rise of the People's Republic of China (PRC) as a regional political and economic power with global aspirations is one of the principal elements in the emergence of East Asia, a region that has changed greatly over the past quarter of a century. China's emergence has significant implications for the region and the world. The United States welcomes the rise of a peaceful and prosperous China, one that becomes integrated as a constructive member of the international community. But, we see a China facing a strategic crossroads. Questions remain about the basic choices China's leaders will make as China's power and influence grow, particularly its military power. […] This report outlines what we know of China's national and military strategies, progress and trends in its military modernization, and their implications for regional security and stability. But, secrecy envelops most aspects of Chinese security affairs. The outside world has little knowledge of Chinese motivations and decision-making and of key capabilities supporting PLA [People's Liberation Army] modernization. Hence, the findings and conclusions are based on incomplete data. These gaps are, of necessity, bridged by informed judgment."
