Abstract: The paper challenges the notion that Chinese maritime coercion in the East and South China Seas (ESCS) is best described as a grey zone strategy. The ‘grey zone’ notion raises two issues. Conceptually, it adds little to the existing literature on maritime coercion. Practically, it creates confusion over the understanding of maritime coercion by blurring the distinction between military and constabulary activities. The paper articulates this difference to elucidate the functional correlation between Beijing’s strategic objectives and maritime claims. Within this context, the grey zone construct is particularly problematic since it uncritically assumes that the use of force is designed to remain below the threshold of war. By contrast, the paper argues that Chinese maritime claims to control ‘rights and interests’ are a function of a broader strategic intention to project military power within and beyond the confines of the ESCS, whilst preventing others to do the same. Thus, Chinese maritime coercion (military and constabulary) increases strategic competition and the risk of war, and is therefore better described as part of a ‘hybrid’ strategy.
