Key takeaways

List of countries that border only one other country belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect List of countries that border only one other country to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of List of countries that border only one other country from memory before moving on to harder problems.

Reference excerpt

This is a list of sovereign state that have a land border with only one other. Some on this list have a maritime border with additional countries. Some which are not listed here have no land border but do have a maritime border with a single other state; an example is Sri Lanka. There are generally three arrangements by which a state would have a single land border:

an island divided between two states, such as Haiti and the Dominican Republic, or Republic of Ireland and the United Kingdom. a peninsula or a semi-enclave, where one state has a land border with a neighbouring one but is otherwise surrounded by sea, while the neighbour borders other states—examples are Portugal (neighbouring Spain), The Gambia (surrounded by Senegal) and Brunei (surrounded by Malaysia). the three states that are landlocked enclaves, surrounded by a larger state: San Marino and Vatican City (within Italy) and Lesotho (within South Africa). Territory leased or ceded by one country to another for perpetual use, but not in sovereignty, such as Guantanamo Bay Naval Base in Cuba, or memorials, such as the American Cemetery in France, do not constitute true territorial borders because the land occupied remains a formal part of the host country. This list is based on the Correlates of War Direct Contiguity data set, with maritime causeways, bridges and artificial islands not being counted.

States bordering only one other sovereign state This section considers only sovereign states, not constituent countries like Wales and Scotland, which border only England, or dependent territories such as Gibraltar, which has an international border with Spain but is not legally part of the United Kingdom. Also not counted are borders on artificial islands such as Passport Island, which is the only land border of Bahrain.

Landlocked

With coast

With partially recognized countries

Causeways, bridges, and tunnels

Often called fixed crossings or fixed links, transportation corridors constructed to cross bodies of water without any intermittent connections such as ferries or ships may be between different states. These may be considered artificial "persistent" borderpoints for land vehicles or pedestrians, but are not typically considered land borders given their need for continuous operation and maintenance, as well as their ease of volume control or closure by either state. Two countries are islands and have no land borders, but maintain fixed borderpoints with other nations.

Dependent territories In some cases, a dependent territory of one nation borders another nation.

Integral parts of sovereign states In most cases, an integral part of a larger country shares a border with another nation.

Historical Many countries historically had only one neighbour. Some no longer exist while others now have either no land borders or borders with more than one nation due to border changes.

Canada: bordered only by the United States until 2022, it now shares a short border with the Kingdom of Denmark at Hans Island, with Canada's Nunavut on one side and Denmark's Greenland on the other side. Kingdom of Denmark: bordered only by Germany (with a causeway connecting it to Sweden) until 2022 (the constituent country of Denmark still only borders Germany), it now shares a short border with Canada at Hans Island, with Canada's Nunavut on one side and Denmark's Greenland on the other side. Korea: bordered only China for several hundred years before 1860, after which a second international border with Russia appeared (approx. 17 km (11 mi) long), according to the Convention of Peking. Following the division of Korea in 1945 only North Korea now shares this border. Ciskei: one of the Bantustans of South Africa; created under apartheid, reincorporated on April 27, 1994. Venda: another Bantustan, Venda was a true enclave bordering only South Africa and separated narrowly from Zimbabwe by the Madimbo corridor to the north; reincorporated on April 27, 1994. Newfoundland: with Canada, until March 31, 1949, when it became the Canadian province of Newfoundland (now named Newfoundland and Labrador). Scotland and England: bordered each other until 1707 when they were united as Great Britain by the Acts of Union, see Anglo-Scottish border. Japan: bordered Russia on the island of Sakhalin from 1905 until 1910, until Japan inherited the China–North Korea border and the North Korea–Russia border upon the Japanese annexation of Korea. Both Sakhalin and Korea were relinquished after Japan's defeat in World War II in 1945. (See Karafuto Prefecture and Empire of Japan). Weihaiwei: 1898–1930, British colony on a leased territory from China's Qing dynasty. Transferred to the Republic of China in 1930. Tasmania: bordered only by the Colony of Victoria (on Boundary Islet), until the federation of the Commonwealth of Australia in 1901. Hong Kong: bordered China 1860–1997 as a crown colony of the United Kingdom. Transferred to the People's Republic of China in 1997. Macau: bordered China until 1999 as a colony of Portugal. Transferred to the People's Republic of China in 1999.

Worked examples

Example 1 — a first encounter with List of countries that border only one other country

Start with the simplest possible case. Write down what List of countries that border only one other country claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to List of countries that border only one other country before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about List of countries that border only one other country ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of List of countries that border only one other country

In research: List of countries that border only one other country appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses List of countries that border only one other country in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: List of countries that border only one other country is common in secondary-school and first-year university syllabi. It links to neighbouring topics Border-related lists, Lists of countries by geography, so understanding it makes those chapters shorter.
In everyday life: Look for List of countries that border only one other country outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
