China on May 1 moved its giant indigenous oil rig, Hai Yang Shi You (HYSY) 981, southward in the South China Sea (SCS). The new location, only 120 miles from Vietnam’s shore, is well within Vietnam’s continental shelf and its Exclusive Economic Zone (EEZ). To support and protect this oil drilling structure, China dispatched over 80 vessels, a number that continues to rise. Foreign ships are warned to stay away from the rig for security and safety.
