Whose sovereignty over Xisha Islands?

Tensions between China and Vietnam over sovereignty issues in the South China Sea flared up again on May 2, 2014 when China positioned an oil rig in waters off the disputed Xisha Islands. Vietnam protested this action and sent vessels to disrupt the rig's operations. China responded by sending more ships to protect the rig. Inevitably with the numbers of opposing vessels in the area, a violent clash occurred on May 7 injuring some Vietnamese personnel and damaging some vessels.

Vietnam has launched a strong diplomatic and public relations campaign to support its position. It appears to be winning the public relations battle with much global commentary supporting its claim that the rig is illegal and painting the situation as yet another example of China's assertiveness. However, a closer look at the situation suggests that China may be within its rights with the rig. Undoubtedly, however, it could have handled the situation more diplomatically rather than acting unilaterally in a way that inevitably would lead to increased tension.
