'Boundary delimitation differs from boundary demarcation.' Elaborate in the context of ongoing India-China talks.

Boundary-making proceeds in stages: allocation of territory by political agreement, delimitation of the agreed line on maps and in treaty text, and demarcation by physically marking it on the ground with pillars and joint surveys. India and China, negotiating through the Special Representatives (SR) mechanism set up in 2003 [1], remain at the first two stages — a distinction the 25th SR round in Beijing (August 2026) makes concrete.

Delimitation: defining the line on paper

• A political-diplomatic exercise — negotiators agree on the alignment's description, coordinates and map depiction, guided by the 2005 Agreement on Political Parameters and Guiding Principles [2].
• In the India-China case, it is preceded by an even more basic task: clarification and confirmation of the Line of Actual Control (LAC), since the two sides hold differing perceptions of where the line runs [1].
• Institutionally handled by the Expert Group on Boundary Delimitation, created under the SR framework, which the 2026 round tasked with advancing discussions towards an "early harvest" [3].

Demarcation: marking the line on the ground

• A technical-cartographic exercise by joint survey teams erecting boundary pillars — undertaken only after a delimitation treaty exists, as India completed with Bangladesh following the 2015 Land Boundary Agreement.
• No such stage has begun with China; instead, the parties manage an undefined line through confidence-building measures — additional hotlines in the Eastern and Middle Sectors, extra military commander meeting points, and hydrological data-sharing on trans-border rivers agreed in 2026 [3].
• Day-to-day border management rests with the WMCC, distinct from the political SR channel [1].

Thus delimitation settles what the boundary is; demarcation settles where it physically lies. Conflating the two overstates present progress, since the 2026 outcomes are stabilising measures rather than a settlement. A calibrated path — LAC clarification, then delimitation, then demarcation — backed by sustained CBMs and border infrastructure offers the most realistic route to a peaceful, mutually acceptable boundary.
