China's 2015 National Defense Strategy aimed to complete building a moderately prosperous society by 2021 and a modern socialist country by 2049. It emphasized cooperation with other countries while avoiding directly addressing competition with the US. The strategy highlighted China's ongoing military reforms to build stronger joint warfare capabilities. It also noted increasing challenges, including territorial disputes, US military presence in Asia, and threats to China's stability from separatist forces. While focusing on developing a strong military as part of its national rejuvenation, the strategy stressed China's military would adhere to the Communist Party's leadership and pursue combat effectiveness.
