China's reemergence as a great power over the next few decades represents the primary strategic challenge for the U.S.-Japan security alliance and for the East Asian security landscape writ large. A clearer understanding of the fundamental underpinnings and trajectory of China's foreign policy and security strategies toward the region is necessary to navigate these challenges and assure stability and prosperity in Asia.
