This study assesses the context and motivations of the PRC's use of military force since 1949. It then extracts Beijing's use of its calculus of warning statements in detail from several instances in which it has threatened and, in some cases, actually followed through with the use of military force to resolve a dispute. It offers several points to take into account in watching for and analyzing Beijing's use of this warnings calculus in contemporary contexts, and it offers a hypothetical scenario in which this calculus might appear in the context of China's claims in the South China Sea. -- Excerpted from introduction.
