The land border between the two countries described herein is depicted by a red line on the map at a scale of 1/50,000 jointly determined by both parties, the length and area used in describing the border are measured from this map. The set of maps attached to this Agreement is an integral part that cannot be separated from the Agreement.

Article III.The two Parties agree that the exact location of the meeting point of the border between the three countries of the Socialist Republic of Vietnam, the People's Republic of China, and the Lao People's Democratic Republic will be determined through mutual agreement among the three countries.

Article IV. The plane standing along the land border between Vietnam and China mentioned in Article II of this Treaty shall delimit the airspace and underground space between the two countries.

Article V.The contracting Parties agree that, except where clearly provided for in this Treaty, the Vietnam-China border mentioned in Article II, for sections where rivers or streams form the boundary, shall follow the median line of the flow or main current where boats cannot navigate, and the median line of the main navigable channel where boats can navigate. The exact position of the median line of the flow, main current, or median line of the main navigable channel, and the attribution of sandbanks and shoals on the border rivers or streams shall be specifically determined by the contracting Parties when demarcating and setting up boundary markers.

The primary standard for determining the main current is the flow rate at the average water level.

The primary standard for determining the main navigable channel is the depth of the main navigable channel combined with its width and radius of curvature. The median line of the main navigable channel is the median line of the water surface between the corresponding equal-depth contour lines marking the main navigable channel.

Any changes that may occur to the border rivers or streams shall not alter the direction of the border line, nor affect the position of the Vietnam-China border line already established on the ground or the attribution of sandbanks and shoals, unless the contracting Parties reach a different agreement. New sandbanks and shoals appearing on the border rivers or streams after the border line has been established on the ground shall be delimited according to the already established border line. If new sandbanks and shoals appear on the border line already established on the ground, the contracting Parties will negotiate to determine their attribution based on fairness and reasonableness.
