Definition

Yuen Yuen Ang theorizes ambiguous policy communication as serving an adaptive function: ambiguity gives agents room to interpret, experiment, and flexibly implement policies when leaders face complex problems whose solutions cannot be fully specified in advance. 

In Ang’s 2016 formulation, later formalized as Adaptive Policy Communication, ambiguous “grey” directives function alongside clear signals—grey grants flexibility, black authorizes, and red restricts—and their combination varies across policy domains and leaderships.  

Ang’s later work (2023; 2026) measures policy communication using computational methods, translating her theory of ambiguity into large-scale datasets.

Quotes

[Original articulation: ambiguity permits experimentation and feedback] A second, ‘gray’ variety comprises policy statements where the leadership is deliberately ambiguous about what can and cannot be done. These policies permit local experimentation and variation because restrictions are not explicitly stated. Adaptive responses to ambiguous directives produce feedback that then informs the central authorities about how policies should be adjusted.

[Ambiguity provides room for local interpretation] The central state essentially deflected the thorny political problem of how to handle competition between collective and state-owned enterprises back to the local authorities. Additionally, note that the guidelines did not even specify who the local authorities were; instead it invoked the amorphous phrase ‘the relevant departments’ (a term that, until this day, commonly appears in official Chinese documents). These ‘relevant departments’ were advised to decide whether or not to set up nonstate firms ‘based on their assessments of the pros and cons.’ In colloquial terms, the document essentially says: you (whoever you are) decide for yourself whether this works for you.

[From theory of adaptive governance to measurement] This article advances a revised model of Chinese policy communication, focusing on central directives – laws, commands and guidelines that flow from the very top. It posits that, contrary to popular impression, the flexibility of Chinese policy-making is not simply achieved by ‘frequently [giving] vague directives.’ Rather, adaptive governance is achieved through a combination of three varieties of directives – grey, black and red – with each serving a distinct function respectively: granting flexibility; affirming; and restricting. 

— Ang, “Ambiguity and Clarity,” p. 16.  

[Expanding typology from grey to charcoal] Building on Ang’s original typology of three policy signals (Black = Authorizing, Red = Prohibiting, Grey = Ambiguous), we extend it into five categories by adding Yellow (Pressuring) and Charcoal (Flexible). This expanded typology captures finer variation in policy signals and, in particular, it captures Yellow and Charcoal signals that have become more salient under Xi Jinping’s leadership.
