Book excerpt: This book project evaluates the applicability and effectiveness of UNCLOS as a settlement mechanism for addressing ocean disputes. Focus is placed on the South China Sea (SCS) dispute, one of the most complex and challenging ocean-related conflicts in the world. The book considers the internal coherence of the Law of the Sea Convention regime and its dispute settlement procedures. It looks at the participation in the UNCLOS negotiation, maritime legislation, and dispute settlement practice of relevant States party to the dispute. The book goes on to explore the relationship between UNCLOS and other regimes and institutions in general in the SCS, particularly in regard to maritime security, marine environment protection, oil and gas joint development and political interaction.
