U.S. South China Sea strategy plan

This bill would state U.S. policy toward the South China Sea and require the Secretary of State, with the Secretary of Defense, to deliver a Strategy for Diplomatic Engagement to the Senate Foreign Relations Committee and the House Foreign Affairs Committee within 180 days of enactment. The strategy would be unclassified but could include a classified annex. It would lay out U.S. goals on security, law, and trade; name a lead office for each goal; analyze State Department programs and gaps; and include plans for deeper bilateral and collective engagement and crisis management short of war. The Secretary would also have to list program, policy, and budget needs for fiscal years 2027–2029 and send that assessment within 360 days, then brief those committees within 30 days of submission. If enacted, these steps would guide coordination with allies and help shape future funding and actions, but the bill would not itself provide new money.
