China’s emergence as a global economic superpower, and as a major regional military power in Asia and the Pacific, has had a major impact on its relations with the United States and its neighbors. China was the driving factor in the new strategy the United States announced in 2012 that called for a “rebalance” of U.S. forces to the Asia-Pacific region. At the same time, China’s actions on its borders, in the East China Sea, and in the South China Sea have shown that it is steadily expanding its geopolitical role in the Pacific and having a steadily increasing impact on the strategy and military developments in other Asian powers.

China’s military development has become a key focus of US security policy as well as that of virtually all Asia-Pacific states. This report from the CSIS Burke Chair in Strategy examines trends in Chinese strategy, military spending, and military forces based on Chinese defense white papers and other official Chinese sources; US reporting by the Department of Defense and other defense agencies; and other government sources, including Japanese and Korean defense white papers and the International Monetary Fund. The analysis also draws on the work of experts outside of government, various research centers, and nongovernmental organizations.

Conventional wisdom portrays the People's Republic of China (PRC) People's Liberation Army (PLA) as a backward continental force that will not pose a military challenge to its neighbors or to the United States well into the 21st century. PLA writings that demonstrate interest in exploiting the revolution in military affairs (RMA) are dismissed by a large segment of the PLA- watching community as wistful fantasies. The author offers an alternative perspective by outlining emerging PLA operational concepts and a range of research and development projects that appear to have been heavily influenced by U.S. and Russian writings on the RMA. Fulfillment of the PLA's vision for the 21st century could have significant repercussions for U.S. interests in the Asia-Pacific region.

CSIS senior adviser Mark Cancian annually produces a series of white papers on U.S. military forces, including their composition, new initiatives, long-term trends, and challenges. This report is a compilation of these papers and takes a deep look at each of the military services, the new Space Force, special operations forces, DOD civilians, and contractors in the FY 2021 budget. This report further includes a foreword regarding how the Biden administration might approach decisions facing the military forces, drawing on insights from the individual chapters.

In late 2015, the People's Liberation Army (PLA) initiated reforms that have brought dramatic changes to its structure, model of warfighting, and organizational culture, including the creation of a Strategic Support Force (SSF) that centralizes most PLA space, cyber, electronic, and psychological warfare capabilities. The reforms come at an inflection point as the PLA seeks to pivot from land-based territorial defense to extended power projection to protect Chinese interests in the "strategic frontiers" of space, cyberspace, and the far seas. Understanding the new strategic roles of the SSF is essential to understanding how the PLA plans to fight and win informationized wars and how it will conduct information operations.
