evidence: Vietnam/China: Chinese Oil Rig Operations Near the Paracel Islands [...] China’s decision to introduce an oil rig accompanied by numerous government vessels for the first time in waters disputed with Vietnam is provocative and raises tensions. This unilateral action appears to be part of a broader pattern of Chinese behavior to advance its claims over disputed territory in a manner that undermines peace and stability in the region. [...] Sovereignty over the Paracel Islands is disputed; this incident is occurring in waters claimed by Vietnam and China near those islands. These events highlight the need for claimants to clarify their claims in accordance with international law, and to reach agreement on appropriate behavior and activities in disputed areas.
