China's rise as a major international actor is likely to stand out as a defining feature of the strategic landscape of the early 21st century. Sustained economic development has raised the standard of living for China's citizens and elevated China's international profile. This development, coupled with an expanding science and technology base, has also facilitated a comprehensive and ongoing military modernisation program. The United States welcomes a strong, prosperous, and successful China that reinforces international rules and norms and enhances security and peace both regionally and globally. This book examines China's expanding military capabilities which can facilitate co-operation in pursuit of shared objectives with the United States. Strengthening our military-to-military relationship is a critical part of our strategy to shape China's choices as we seek to capitalise on opportunities for co-operation while mitigating risks.
