Which Countries Border the Most Other Nations?

Some countries have a single neighbour; others have more neighbours than most people have close friends. Here is the ranking of the world's most-bordered nations, and why sharing so many borders is both a strategic asset and a constant balancing act.

The joint record holders: China and Russia — 14 neighbours each

China borders Afghanistan, Bhutan, India, Kazakhstan, North Korea, Kyrgyzstan, Laos, Mongolia, Myanmar, Nepal, Pakistan, Russia, Tajikistan and Vietnam. Russia borders Azerbaijan, Belarus, China, Estonia, Finland, Georgia, Kazakhstan, North Korea, Latvia, Lithuania, Mongolia, Norway, Poland and Ukraine. Managing fourteen separate bilateral relationships, each with its own history and disputes, is a full-time diplomatic operation for both giants.

Brazil — 10 neighbours

Brazil borders every South American country except Chile and Ecuador: Argentina, Bolivia, Colombia, French Guiana, Guyana, Paraguay, Peru, Suriname, Uruguay and Venezuela. Its Amazon frontier alone touches seven different countries.

Democratic Republic of the Congo — 9 neighbours

Angola, Burundi, Central African Republic, the Republic of the Congo, Rwanda, South Sudan, Tanzania, Uganda and Zambia all share a border with the DRC, making it Africa's most-bordered nation and a frequent hub of regional conflict spillover.

Germany — 9 neighbours

Austria, Belgium, Czechia, Denmark, France, Luxembourg, the Netherlands, Poland and Switzerland surround Germany, a legacy of sitting at the very centre of the European continent — which explains both its historical vulnerability to invasion and its modern role at the heart of the EU.

Also with 9 neighbours: Turkey, Zambia, Sudan, France, Tanzania and Austria

Several other countries tie near the top of the list, including Turkey (bridging Europe and the Middle East), Zambia and Tanzania (both hubs of Southern and East Africa), Sudan, France (thanks to overseas department French Guiana's own borders) and Austria.

The other extreme: countries with just one neighbour

• Portugal — only Spain
• Canada — only the United States (by land)
• Haiti — only the Dominican Republic
• South Korea — only North Korea
• Denmark (mainland) — only Germany
• Ireland — only the United Kingdom

Islands and near-islands with a single land neighbour tend to develop very different foreign policy habits than nations juggling a dozen borders at once — often closer, deeper relationships with that one neighbour rather than a wide diplomatic balancing act.

Why border count matters

More borders generally means more trade routes and cultural exchange, but also more potential flashpoints, refugee flows and border disputes to manage simultaneously. It is no coincidence that China, Russia and the DRC — the most-bordered countries — also feature regularly in international border-dispute headlines.

Test your border knowledge

Spin a country and try to name every neighbour before checking the country page. China or Russia will genuinely test you — but Portugal and Haiti are free points if you already know the trick.
