MANILA — Indonesia's Foreign Minister Retno Marsudi said on Tuesday her country is ready to work with other Southeast Asian nations to finalize a long-delayed code of conduct for the South China Sea, where many of its neighbors have overlapping claims with China.

"On South China Sea, Indonesia is ready to work together with all ASEAN member states including the Philippines to finalize the Code of Conduct as soon as possible," Retno said at a joint press conference with Filipino counterpart Enrique Manalo in Manila, ahead of a visit by Indonesian President Joko Widodo.
