A gas pipeline is not one kind of object on a map. The source data supports three genuinely different physical/political shapes, and treating them as interchangeable lines on the same chart would flatten the real argument.

The source's own European section names an unusually dense interconnector web, not a simple point-to-point set of pipes:
Russian-sourced projects — Nabucco (Turkey-Austria, cancelled) and South Stream (Black Sea-Bulgaria-Serbia-Italy, cancelled) — showing that even Europe's mesh has failed links that never got built at all.
The design logic of a mesh is that no single pipe is a single point of failure — gas can reroute. That logic was tested directly on 26 September 2022, when four explosions along the seabed disabled three of the four Nord Stream 1/2 lines running from Russia to Germany. German investigations through 2024-2025 concluded a diver team directed by Ukrainian officials was responsible; a Ukrainian national was named in a June 2024 German arrest warrant. Sweden and Denmark opened and then closed their own investigations without independent public conclusions. Russia has pointed at the West since the attack. This attribution remains contested, not settled — stated here as an open dispute, not a resolved fact.
The mesh absorbed the loss: Nord Stream's destruction did not collapse Europe's gas supply outright, because the web has other links. But it did convert a physical engineering redundancy into a live geopolitical wound — the pipe itself survived as a mesh-design case study of why you build redundancy, while the single destroyed segment became the subject of an unresolved international dispute that outlived the metal.
Russia-to-China gas moves through a structurally opposite design: Power of Siberia, a single dedicated pipeline (Gazprom-operated, from Yakutia through Primorsky Krai to China), built on a 30-year, $400 billion deal signed 21 May 2014. Construction began September 2014; gas deliveries began 2 December 2019; China imported 4.1 billion cubic meters in 2020, ramping toward a stated 38 bcm target by 2023.
There is no mesh here — no alternate route, no interconnector web, one seller and one buyer joined by one line. And the source states the strategic reason for this design choice directly, in its own words: the pipeline gives Russia "another economic partnership in the face of resistance to pipelines being built in Western Europe." Power of Siberia is not simply a second gas customer for Russia — it is the structural answer to the mesh-country's political resistance, built as a single unmeshed bilateral line specifically because the mesh option had closed.
A third category appears directly in the source's own annotations, and it deserves its own map layer rather than being folded into either of the above: pipelines named, planned, negotiated, and in one case under physical construction, but not yet carrying gas.
India) — listed explicitly as (planned) in the source's own text.
construction)**, one stage further along than TAPI but still not an operating chokepoint.
route from Russia to China, distinct from the operating eastern route above, itself still (planned) per the source.
These are drawn on the map not as failures but as a genuine third structural category: political and commercial commitments made years before a single cubic meter moves, each one a bet on a future chokepoint that the operating pipelines above have already survived, been destroyed, or been built around.
The source's own North America section runs under a different regulatory frame entirely — interprovincial pipelines regulated by Canada's National Energy Board, intrastate lines by the US Federal Energy Regulatory Commission (FERC) — and names a dense domestic network distinct from the international-supply-line logic above: Alliance Pipeline, Maritimes & Northeast Pipeline, and TransCanada PipeLines (Canada); Burgos-Monterrey, Los Ramones, and Agua Prieta (Mexico, several explicitly cross-border-fed); Algonquin Gas Transmission, ANR Pipeline, Columbia Gas Transmission, El Paso Natural Gas, and Enbridge among dozens of major US interstate lines; and Puerto Rico's Vía Verde Pipeline. This region's pipelines mostly move gas within a single continental market under shared regulatory bodies, a structurally different problem than Europe's cross-sovereign mesh, Russia-China's single bilateral export line, or South/Central Asia's still-unbuilt promises.
A pipeline map that only draws lines on a globe misses the actual distinction the source data supports: three pipelines can look identical as ink on a chart and still mean three different things —
loss of one node, but that node's destruction becomes a geopolitical dispute that outlives the physical repair;
built specifically because the mesh option was politically closed to its owner;
pipeline that exists as a negotiated commitment and, in one case, a physical construction site, but not yet as flowing gas at all.
The map is not simply "where the pipes are." It is a record of three different bets on how a nation secures the right to move gas across someone else's border — redundancy, exclusivity, or promise — and what happens to each bet when it is tested.
