On October, 21st 2010, Chinese State Bureau of Surveying and Mapping launched Map World, its online map service, at www.tianditu.cn and www.chinaonmap.cn, in which the nine-dotted line is present and encroaches Hoang Sa (Paracel) and Truong Sa (Spratly) Archipelagos and the waters of Vietnam. In response to question from the media regarding Vietnam reaction to this, Ministry of Foreign Affairs' Spokesperson Nguyen Phuong Nga on November, 5th 2010 stated:

“The act by the Chinese State Bureau of Surveying and Mapping  (SBSM) seriously infringes upon Vietnamese sovereignty over Hoang Sa (Paracel) and Truong Sa (Spratly) Archipelagos, sovereign rights and national jurisdiction over Vietnam’s continental shelf  and exclusive economic zone of 200 nautical miles. It also violates the 1982 United Nations Convention on the Law of the Sea and goes against the Declaration on the Conduct of Parties in the South China Sea (DOC) signed between ASEAN and China.
Vietnam opposes SBSM’s act and requests the Chinese side  to promptly remove from SBSM map service all data and information that  violate Vietnam’s sovereignty,sovereign rights and national jurisdiction over Hoang Sa (Paracel), Truong Sa (Spratly) Archipelagos and the waters  of Vietnam and to abide by the common perception of Leaders of the two countries on maintaining peace and stability, and refraining from complicating or expanding disputes in the East Sea.”
