3The book investigates China's relations to the outside world between ca. 100 BCE and 1800 CE. In contrast to most histories of the Silk Roads, the focus of this book clearly lies on the maritime Silk Road and on the period between Tang and high Qing, selecting aspects that have so far been neglected in research on the history of China's relations with the outside world. The author examines, for example, issue of 'imperialism' in imperial China, the specific role of fanbing 蕃兵 (frontier tribal troops) during Song times, the interrelationship between maritime commerce, military expansion, and environmental factors during the Yuan, the question of whether or not early Ming China can be considered a (proto-)colonialist country, the role force and violence played during the Zheng He expeditions, and the significance the Asia-Pacific world possessed for late Ming and early Qing rulers.
