Vietnam says China has moved an oil rig into disputed waters in the South China Sea that could be a repeat of the 2014 standoff between the communist neighbors.
Foreign Ministry spokesman Le Hai Binh said in a statement posted on the ministry's website late Tuesday that Vietnam had raised concerns with China over the movement of the Haiyang Shiyou oil rig and has demanded that China stop any drilling and remove the oil rig from the area where the two countries' continental shelves overlap.
He says Vietnam wants to protect its legal rights and interests in the area in line with international law.
The oil rig was at the center of a standoff between the countries in May 2014. The incident sparked deadly anti-China riots in Vietnam.
