The IHO's Limits of Oceans and Seas, 3rd ed., the current formal international standard, does not delimit the Taiwan Strait and includes its waters within the South China Sea. The unapproved draft for the next edition defines the strait and places it between the two seas. Informal usage already distinguishes the strait from the two seas.
