2014 Vietnam anti-China protest was a series of anti-China protests followed by unrest and riots across Vietnam in May 2014, in response to China deploying an oil rig in a disputed region of the South China Sea.

The Hai Yang Shi You 981 standoff, also known as the 2014 China-Vietnam oil rig crisis, refers to the tensions between China and Vietnam arising from the Chinese state-owned China National Offshore Oil Corporation moving its Hai Yang Shi You 981 oil platform to waters near the disputed Paracel Islands in South China Sea, and the resulting Vietnamese efforts to prevent the platform from establishing a fixed position. According to an announcement by the Hainan Maritime Safety Administration of China, the drilling work of the Hai Yang Shi You 981 would last from May 2 to August 15, 2014. On July 15, China announced that the platform had completed its work and withdrew it fully one month earlier than originally announced.
