Drawing on an in-depth analysis of hundreds of primary BRI documents, the book offers a comprehensive overview of China's most crucial foreign policy agenda item. It demonstrates how, through the BRI, the PRC has introduced mechanisms to the international level, which reflect its domestic policy-making mode. In addition, the PRC has institutionalized the initiative by establishing China-centered BRI networks across a wide range of policy areas. Within those emerging China-centered BRI networks, the PRC systematically increases its international discursive power, for example, by inserting Chinese vocabulary into UN resolutions or by promoting Beijing's approaches vis-à-vis "the rule of law" across a range of developing states. This book also further discusses the implications of the BRI for the international legal order.
