In the People's Republic of China, campaigns are an established means for achieving political and legal aims. Since the beginning of the economic reform, the country has seen a rapid economic development, which is a reason for both the constant development of the local legal system and the attractiveness of China for foreign workers. This book examines the role of campaigns in the context of China's immigration law, which was reformed in 2012. It examines why the revision of the Exit and Entry Administration Law was accompanied by increased campaigning against illegal immigration and illegal employment of foreigners. To this end, this book examines both the internal structure of the campaigns and the embedding of the current immigration law in the context of Chinese administrative law.
