Beijing has announced plans to put two more lighthouses in the disputed South China Sea into operation by the end of the year, state media has reported.

Construction on lighthouses on Mischief and Fiery Cross Reefs — both in the contested Spratly Island chain — is being rushed, and will provide navigational services to ships in the vicinity, the official Xinhua News Agency reported Monday.

China has used massive land reclamation projects to build man-made islands on both reefs.
