Capitalist peace theory (CPT) has gained considerable attention in international relations theory and the conflict literature. Its proponents maintain that a capitalist organization of an economy pacifies states internally and externally. They portray CPT either as a complement or as a substitute to other liberal explanations such as the democratic peace thesis. They, however, disagree about the facet of capitalism that is supposed to reduce the risk of political violence. Key contributions have identified three main drivers of the capitalist peace phenomenon: the fiscal constraints that a laissez-faire regimen puts on potentially aggressive governments, the mollifying norms that a capitalist organization creates; and the increased ability of capitalist governments to signal their intentions effectively in a confrontation with an adversary. Defining capitalism narrowly through the freedom entrepreneurs enjoy domestically, this article evaluates the key causal mechanisms and empirical evidence that have been advanced in support of these competing claims. The article argues that CPT needs to be based on a narrow definition of capitalism and that it should scrutinize motives and constraints of the main actors more deeply. Future contributions to the CPT literature should also pay close attention to classic theories of capitalism, which all considered individual risk taking and the dramatic changes between booms and busts to be key constitutive features of this form of economic governance. Finally, empirical tests of the proposed causal mechanism should rely on data sets in which capitalists appear as actors and not as “structures.” If the literature takes these objections seriously, CPT could establish itself as central theory of peace and war in two respects. First, it could serve as an antidote to the theory of imperialism and other “critical” approaches that see in capitalism a source of conflict rather than of peace. Second, it could become an important complement to commercial liberalism that stresses the external openness rather than the internal freedoms as an economic cause of peace and that particularly sees trade and foreign direct investment as pacifying forces.
China’s economic rise has been accompanied by the maturation and increasing professionalization of academic disciplines in China, including the discipline of international relations. The emergence of an indigenous international relations discipline in China has led to an intense debate about the development of a distinctive “Chinese School” that draws on China’s intellectual traditions and historical record to inspire the development of new international relations theories. While the debate continues, the outlines of a Chinese School are becoming clear. The Chinese School of international relations theory draws on Confucian concepts of relationality and hierarchy to theorize the character of the relations between countries rather than focus on the attributes of countries themselves. It also highlights the historical existence of interstate systems organized in a hub-and-spoke pattern around a single, central state.
The premodern East Asian world-system in which China was embedded and classical Chinese scholars developed their ideas was a central state system. Premodern China was always by far the dominant state in East Asia, with the result that international relations in the East Asian world-system exhibited a hub-and-spoke pattern centered on China, as in the tributary system of the Ming and Qing Dynasties. Moreover the Confucian worldview that ultimately came to be China’s state ideology served in effect as the governing moral code of the system as a whole. The combination of a central state structure with a universal moral code created what in Chinese is called a tianxia (“all under heaven”), a world-embracing system of governance centered on a particular state, in this case China.
In a tianxia system international relations tend to be hierarchical because of the clear power differentials between the central state and other states. They can be either expressive (showing social solidarity) or purely instrumental, depending on the stance taken by the central state. Chinese School international relations theorists tend to assume that the “best” (most stable, most peaceful, most prosperous, etc.) world-system configuration would be a tianxia system dominated by expressive rationality and centered on China, but this is no more self-evident than the widely held Western preference for a liberal, rules-based order. What Chinese School international relations theory really offers the discipline is a new set of concepts that can be applied to the theorization and empirical analysis of today’s millennial world-system. This postmodern interstate system appears to be a central state system with a universal moral code, an American tianxia based on individualism. The historical Confucian Chinese tianxia may be the best precedent for modeling this system.
