The World's Most Contested Borders: What WorldRelat's Dispute Data Shows
2026-09-19 · by Jordi Fuster
Alongside its relationship scores, WorldRelat tracks active territorial disputes for every country in its database — 357 of them right now, spread across 124 countries. Zoomed out, that data draws a pretty clear map of where the world's hardest border questions actually sit.
Who carries the most
Taiwan tops the list with 32 active disputes on record, followed by China with 26 and India with 15. That's not a coincidence of naming — Taiwan and China's overlapping claims run through the same set of features, most notably in the South China Sea, so a single contested reef or shoal can generate a dispute entry for both. The United States and Russia each carry 11, France 9 (largely a function of its scattered overseas territories), and Croatia 8.
Three disputes worth knowing by name
Kashmir is the most consequential single dispute on the list: nine separate entries across India, Pakistan, China and Taiwan, covering Jammu and Kashmir, Ladakh, the Trans-Karakoram Tracts, and Azad Kashmir and Gilgit-Baltistan. It's the same underlying conflict that produced the four-day India-Pakistan war of May 2025 — see our deeper look at that relationship.
The South China Sea disputes form the densest cluster in the entire dataset: 15 entries across China, Taiwan, Vietnam, the Philippines, Malaysia and Brunei, over features like the Spratly Islands, the Paracel Islands, James Shoal and Macclesfield Bank — a genuinely six-sided dispute, which is part of why it has proven so resistant to resolution.
Crimea appears as a two-entry dispute between Russia and Ukraine — a comparatively simple bilateral entry, in dispute-count terms, for what has become one of the most consequential conflicts of the decade. It's a good reminder that the number of parties to a dispute says nothing about its stakes.
What this data is, and isn't
This is a record of documented, currently active claims — not a ranking of severity, and not a prediction of where the next conflict will start. A dispute with dozens of quiet decades behind it, like Argentina and the United Kingdom's claims over the Falkland Islands, sits in the same table as one with an active shooting conflict attached. What the raw count is genuinely good for is a first, honest map of where the world's unresolved lines actually are — a starting point for anyone using the World map to understand a country's neighborhood, not the full picture on its own.
