Countries With the Most Borders: China and Russia (14 Each)

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.

France — 8 neighbours in Europe, 11 with its overseas regions

In Europe, France borders Andorra, Belgium, Germany, Italy, Luxembourg, Monaco, Spain and Switzerland. Count its overseas regions the way Brazil's total counts French Guiana, and three more appear: Brazil and Suriname (via French Guiana) and the Netherlands (via Saint Martin, an island shared with Dutch Sint Maarten). On that rule France has 11 neighbours, one more than Brazil, which is why some rankings put it third.

Eight neighbours: Austria, Tanzania, Turkey and Zambia

• Austria — Czechia, Germany, Hungary, Italy, Liechtenstein, Slovakia, Slovenia and Switzerland
• Tanzania — Burundi, the DRC, Kenya, Malawi, Mozambique, Rwanda, Uganda and Zambia
• Turkey — Armenia, Azerbaijan, Bulgaria, Georgia, Greece, Iran, Iraq and Syria
• Zambia — Angola, Botswana, the DRC, Malawi, Mozambique, Namibia, Tanzania and Zimbabwe (the Botswana border is only a few hundred metres long, at the Kazungula crossing on the Zambezi)

Sudan used to sit on this list with nine neighbours. The independence of South Sudan in 2011 left it with seven: the Central African Republic, Chad, Egypt, Eritrea, Ethiopia, Libya and South Sudan.

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

Pick a random 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.
