This document analyzes weaknesses in China's People's Liberation Army (PLA) by examining its organization, human capital, combat capabilities, and defense industry. It finds that while the PLA has modernized significantly since the 1990s, weaknesses remain. In particular, it faces challenges in joint operations, non-combat operations, and modern hardware. The PLA is working to address these weaknesses through reforms, but they may limit its ability to achieve all of its missions, including deterring Taiwan independence and defending maritime claims, through 2025. Understanding the PLA's weaknesses is important for assessing its military transformation and implications for US and allied security.
