This book delves into the innovative thinking, new and key agendas, and practical evolution of China's diplomacy in the new era. As the world has entered a new epoch, the once-in-a-century world transformation is accelerating, and great power rivalry becomes increasingly prominent, with the Sino-US strategic competition emerging as the driving force behind the tremendous shifts in international relations. The interaction between China and the world has undergone significant changes, and China's diplomatic adjustments have captured global attention. This book elucidates the underlying logic behind these diplomatic adjustments, summarizes the manifestations of China's diplomatic concepts and innovative practices, highlights the numerous new issues arising from China's interaction with the world, analyzes the challenges and dilemmas faced by Chinese diplomacy, and explores new directions for China's diplomatic breakthroughs. This book serves as a theoretical guide for professional researchers, including experts, scholars, research personnel, and students, while also offering a systematic understanding for a wide range of readers interested in China-related issues, including those in the business world, policy circles, and international activists.
