U.S.-China Strategic Competition in South and East China Seas: Background and Issues for Congress [Updated February 6, 2020] [open pdf - 2MB]
From the Introduction: "This report provides background information and issues for Congress regarding U.S.-China strategic competition in the South China Sea (SCS) and East China Sea (ECS). In an international security environment described as one of renewed great power competition, the South China Sea (SCS) has emerged as an arena of U.S.-China strategic competition. U.S.-China strategic competition in the SCS forms an element of the Trump Administration's more confrontational overall approach toward China, and of the Administration's efforts for promoting its construct for the Indo-Pacific region, called the Free and Open Indo-Pacific (FOIP). [...] The issue for Congress is whether the Trump Administration's strategy for competing strategically with China in the SCS and ECS is appropriate and correctly resourced, and whether Congress should approve, reject, or modify the strategy, the level of resources for implementing it, or both. Decisions that Congress makes on these issues could substantially affect U.S. strategic, political, and economic interests in the Indo-Pacific region and elsewhere."
