Opposition Sen. Franklin saw no reason for a joint investigation between the Philippines and China in relation to the Reed Bank incident earlier this month. Drilon on Monday said a joint investigation will only "derogate our jurisdiction and prejudice our claim" in the West Philippine Sea. "We should not allow it. The law is on our side," Drilon said. "There are clear violations of international treaties and our local laws committed by the Chinese vessel. A joint investigation will only serve their interest, not ours."
