In September 1981, Secretary of Defense Caspar Weinberger asked the Defense Intelligence Agency to produce an unclassified overview of the Soviet Union’s military strength. The purpose was to provide America's leaders, the national security community, and the public a comprehensive and accurate view of the threat.

In the spirit of Soviet Military Power, DIA began in 2017 to produce a series of unclassified Defense Intelligence overviews of major foreign military challenges we face. This volume provides details on China’s defense and military goals, strategy, plans, and intentions; the organization, structure, and capability of its military supporting those goals; and the enabling infrastructure and industrial base. This product and other reports in the series are intended to inform our public, our leaders, the national security community, and partner nations about the challenges we face in the 21st century

China’s double-digit economic growth has slowed recently, but it served to fund several successive defense modernization Five-Year Plans. As international concern over Beijing's human rights policies stymied the PLA’s search for ever more sophisticated technologies, China shifted funds and efforts to acquiring technology by any means available. Domestic laws forced foreign partners of Chinese-based joint ventures to release their technology in exchange for entry into China’s lucrative market, and China has used other means to secure needed technology and expertise. The result of this multifaceted approach to technology acquisition is a PLA on the verge of fielding some of the most modern weapon systems in the world. In some areas, it already leads the world. Chinese leaders characterize China’s long-term military modernization program as essential to achieving great power status. Indeed, China is building a robust, lethal force with capabilities spanning the air, maritime, space and information domains which will enable China to impose its will in the region. As it continues to grow in strength and confidence, our nation’s leaders will face a China insistent on having a greater voice in global interactions, which at times may be antithetical to U.S. interests. With a deeper understanding of the military might behind Chinese economic and diplomatic efforts, we can provide our own national political, economic, and military leaders the widest range of options for choosing when to counter, when to encourage, and when to join with China in actions around the world. This report offers insights into the modernization of Chinese military power as it reforms from a defensive, inflexible ground-based force charged with domestic and peripheral security responsibilities to a joint, highly agile, expeditionary, and power-projecting arm of Chinese foreign policy that engages in military diplomacy and operations across the globe.
Entering the 21st century, China’s leaders rec¬ognized the confluence of several factors that led them to expand the scope and quicken the pace of PLA development: China’s growing global economic and political interests, rapid technology-driven changes in modern warfare, and perceptions of increased strategic-level external threats, including to China’s mari¬time interests. At this time, Chinese leaders perceived a “period of strategic opportunity” wherein the country presumably would not be involved in a major military conflict before 2020, allowing time for economic and military development. As a result, throughout the late 1990s and early 2000s, China’s leaders initi¬ated several practical steps to modernize the PLA as a warfighting instrument.
The PLA has been a politicized “party army” since its inception and exists to guarantee the CCP regime’s survival above all else, serving the state as a secondary role, in contrast to most Western militaries, which are considered apolitical, professional forces that first and foremost serve the state.
China characterizes its military strategy as one of “active defense,” a concept it describes as strategically defensive but operationally offensive. The strategy is rooted in the con¬cept that once Beijing has determined that an adversary has damaged or intends to damage China’s interests at the strategic level, Beijing will be justified in responding “defensively” at the operational or tactical level, even if the adversary has not yet conducted offensive military operations. Beijing interprets active defense to include mandates for deescalating a conflict and seizing the initiative during a con¬flict, and has enshrined the concept in China’s National Security Law (2015) and in the PLA’s major strategy documents.
The PLA often uses the term “informatization” to describe the transformation process of becoming a modern military that can operate in the digi¬tal age. The concept figures prominently in PLA writings and is roughly analogous to the U.S. mil¬itary’s concept of net-centric capability: a force’s ability to use advanced information technology and communications systems to gain operational advantage over an adversary.
The PLA’s Strategic Support Force (SSF), established in December 2015, has an import¬ant role in the management of China’s aero¬space warfare capabilities.121 Consolidating the PLA’s space, cyber, and electronic warfare capabilities into the SSF enables cross-domain synergy in “strategic frontiers.”
