Many studies of China's relations with and influence on Southeast Asia tend to focus on how Beijing has used its power asymmetry to achieve regional influence. Yet, scholars and pundits often fail to appreciate the complexity of the contemporary Chinese state and society, and just how fragmented, decentralized, and internationalized China is today.

In The Ripple Effect, Enze Han argues that a focus on the Chinese state alone is not sufficient for a comprehensive understanding of China's influence in Southeast Asia. Instead, we must look beyond the Chinese state, to non-state actors from China, such as private businesses and Chinese migrants. These actors affect people's perception of China in a variety of ways, and they often have wide-ranging as well as long-lasting effects on bilateral relations. Looking beyond the Chinese state's intentional influence reveals many situations that result in unanticipated changes in Southeast Asia. Han proposes that to understand this increasingly globalized China, we need more conceptual flexibility regarding which Chinese actors are important to China's relations, and how they wield this influence, whether intentional or not.

The Ripple Effect makes the case that to understand China's relationship with Southeast Asia, it is necessary to move beyond a narrow fixation on the Chinese state by scrutinizing the ordinary manifestations of China's presence in the region and recognizing the multifaceted web of actors and their effects on the dynamics between the two regions.
