On January 19, 2016, the Vietnamese Foreign Ministry stated that Haiyang Shiyou 981, the same rig that caused the 2014 dispute, had entered disputed waters in the South China Sea on January 16, 2016. The statement said the rig was still 25 miles from an “assumed median line” between the two countries, but it was in “an overlapping area between the two continental shelves” of Vietnam and Hainan Island, China, which “has not yet been delimited.” It added that China should remove the rig from the disputed waters in accordance with international law. A Vietnamese official met with a Chinese Embassy official on January 18, 2016, to register Vietnam’s “concern.” .
