Lawfulness and Lawfare in the South China Sea
This book explores the subject of “lawfare” (legal warfare) in the South China Sea, analyzing how legal techniques are employed within the context of cognitive and hybrid warfare. The work delves into events, highlighting both aggressive tactics and lawful responses, while also proposing the 3P formula (Publicity, Public Opinion, and Public International Law) as an effective method for mobilizing efforts to protect international law.
The book features numerous illustrations of maritime claims and boundaries, updated to 2025, providing readers with a clear visual perspective. The main benefit of this work is that it offers a comprehensive view with extensive resources and in-depth arguments, making it highly useful for researchers, students, and practitioners. The book is aimed at the shared goal of promoting dispute resolution through fair legal mechanisms, thereby contributing to regional peace and stability.
