Google Maps presents an incorrect boundary line between Vietnam and China, and Vietnam requests that Google correct the mistake according to the official map of Vietnam, Ms Nga said in response to reporters’ questions on March 20.

Vietnam and China signed a protocol on border demarcation and landmark planting, an agreement on land border management regulations and an agreement on border gates and regulations on land border gate management in November 2009.

With the signing of these documents, Ms Nga said, the border between Vietnam and China has been positioned clearly on the map.

Both sides are to ratify the documents according to the law of their respective countries to bring them to life, she said.

The new documents will be deposited at the United Nations and supplied to global mapping and publishing organisations, alongside the 1999 Vietnam-China border demarcation treaty and relevant documents still in effect.
