China Arbitration (2020).

This book focuses on the decision of the Tribunal in the South China Sea Arbitration that China had operated its law enforcement vessels in ways that created risks of collision with Philippine official vessels at Scarborough Shoal in April and May 2012. The book explains the International Regulations for Preventing Collisions at Sea (COLREGS) and the incidents in layperson¿s terms. It analyzes Chinäs violations of the COLREGS on the basis of confidential Philippine documents declassified for the Arbitration, technical works by professional mariners, and the reports submitted by the navigational safety experts to the Tribunal. It pays attention to Chinese post-arbitration critiques of the Tribunal ¿s decision, which it characterizes as rationalizations of collisions as instruments of Chinese foreign policy. It contrasts Chinäs conduct with the practice of the US and Western European States, which mandate compliance with collision regulations even during law enforcement operations. Thebook draws on sources in five languages (English, French, German, Italian, and Spanish), and helps the reader understand the pattern of Chinäs harassment of vessels from littoral and non-littoral States in the South China Sea as well as the absence of legal foundations for Chinäs rationalizations of its behavior.
