A border barrier is a wall, berm or fence, constructed to limit the movement of people across a certain line or border. These structures vary in placement with regard to international borders and topography. The most famous example of border barrier in history is probably the Great Wall of China, a series of walls separating the Empire of China from nomadic powers to the north; the most prominent recent example was the Berlin Wall that surrounded the enclave of West Berlin, separating it from East Germany, during most of the Cold War era.

Barriers by country
In January 2006, Afghanistan's government decreed that the United Nations, the American embassy and other foreign organizations in Kabul must clear concrete security barriers that protect their buildings. Most Kabul streets are full of security barriers and large concrete anti-blast blocks aimed at protecting against the insurgent and terrorist attacks that have risen in the past four years since the fall of the Taliban regime. The decree follows pressure from the newly formed Afghan parliament and public complaints over the heavy traffic jams caused by the barriers. The foreign groups are expressing concern and saying that the security situation does not permit that. The United Nations is one of the organizations concerned by the Afghan government's order. UN chief spokesman in Kabul Adrian Edwards said that security barriers are still required. "We are in a difficult security environment which certainly hasn't improved during 2005", Edwards said. "There have been a number of suicide attacks. Within the UN here, I think none of us would wish to be behind these barricades, we would prefer things could be open as we are in some other countries. However, there have been necessary for our security, that's why they are there." The Afghan government has said it is determined to remove all the barricades. The directive of the government says that "blocking the footpaths, streets, and roads is illegal" and that no one has the right to create obstructions, the only exception being the presidential palace.
In 2003, Botswana began building a 300-mile (480 km)-long electric fence along its border with Zimbabwe. The official reason for the fence is to stop the spread of foot-and-mouth disease among livestock. Zimbabweans argue that the height of the fence is clearly intended to keep out people. Botswana has responded that the fence is designed to keep out cattle, and to ensure that entrants have their shoes disinfected at legal border crossings. Botswana also argued that the government continues to encourage legal movement into the country. Zimbabwe was unconvinced, and the barrier remains a source of tension between the two nations.
Brazil building of huge concrete walls (up to 10 feet in some places) serves as “eco-barriers’” to contain urban sprawl. Officials see it as a means of protecting the forest but critics maintain that it's a strategy for walling in and containing the city’s favelas (slums). The critics argue that the eco-barriers are a cover for cleaning up the city in preparation for the World Cup in 2014 and hosting of the Olympics in 2016.
Brunei is building a security fence along its 20-km border with Limbang to stop the flow of irregular migrants and smuggled goods.
The People's Republic of China (PRC) has two Special Administrative Regions, namely Hong Kong and Macau on its southeastern coast. Both of them maintain controlled intra-national borders with the neighbouring Guangdong province in Mainland China. An identity document is inspected when one crosses the border.
Hong Kong was a Dependent Territory of the United Kingdom until its sovereignty was handed over to the PRC in 1997, while Macau was a Special Territory of Portugal until its sovereignty was handed over to the PRC in 1999. Before the transfers of sovereignty back to the PRC, the Hong Kong–-Guangdong and Macau–Guangdong borders were regarded as international borders.
Under the principle of "One Country, Two Systems", the two Special Administrative Regions continue to maintain their own customs and immigration policies, which are independent of those in Mainland China after the handovers. Due to differences in the policies between the special administrative regions and the Mainland, the Hong Kong–Guandgong and Macau–Guangdong borders have been maintained in operation after the returns.
Hong Kong has a border stretching 32 km with the Shenzhen Special Economic Zone of Guangdong that features fences, thermal image sensors, lights and closed-circuit television. The border is also patrolled regularly by police. Just south of Shenzhen River (the geographical delimitation of the border) is a strip of rural land with restricted access, the 28 km² Closed Area. Currently, the four road border crossings are located at Sha Tau Kok, Man Kam To, Lok Ma Chau and Shenzhen Bay, and a railway and traveller crossing is located at Lo Wu. The residents of the Hong Kong Special Administrative Region are required to have their Hong Kong ID Cards inspected by the Hong Kong Immigration Department and their Home Return Permits inspected by the Public Security Bureau of Guangdong when they cross the border.
Macau has been maintaining a 340-metre controlled border with Zhuhai City in Guangdong with a crossing available at the Border Gate (built in 1870). The border crossing is equipped with 54 counters for travelers and 8 for vehicular traffic. Opened in 1999, the Lotus Bridge in Macau supplemented what has been the only border crossing into mainland China through Border Gate. Both border crossings allow access into Zhuhai.
The Rafah Border Crossing (Arabic: معبر رفح, Hebrew: מעבר רפיח) is an international border crossing between Egyptian and Palestinian-controlled Rafah. It was built by the Israeli and Egyptian governments after the 1979 Israel-Egypt Peace Treaty and 1982 Israeli withdrawal from the Sinai Peninsula, and was managed by the Israel Airports Authority until it was evacuated on 11 September 2005 as part of Israel's unilateral disengagement plan. It has since become the mission of the European Union Border Assistance Mission Rafah (EUBAM) to monitor the crossing.
After having made an agreement with Frontex on the guard of the maritime borders of Greece with Turkey the Greek government decided a wall to be built at the land border with Turkey, the Evros River. These actions have been made as a reaction to the illegal immigration to Greece through the Greco-Turkish borders. These immigrants are originated from Muslim Asian and African states. From January to the beginning of November 2010, 32,500 illegal migrants were intercepted in a single 12.5-kilometer stretch of the Turkish-Greek border along the Evros river. Actually this site is the main entrance of illegal immigrants to the EU from the Asian continent. Illegal immigration is a current subject between the two countries.
Since the mid-1990s, India has been involved in the construction of some of the lengthiest border barriers along its international borders. Six of the nine countries neighboring India are classified as Least Developed Countries. As a consequence, thousands of people from these countries, especially from Bangladesh, Nepal and Burma, illegally immigrate into India.
The Indo-Bangladeshi barrier and Indo-Burma barrier are being built to check smuggling, illegal immigration and possible infiltration by Islamist terrorists. The refugee crisis could also ensue should a climate catastrophe ravage South Asia.
In addition, India completed the construction of the Indian Kashmir barrier which runs along the Line of Control in Kashmir. The purpose of this barrier is to prevent infiltration by armed militants. Many Kashmiris both in Jammu and Kashmir of India and Pakistan Occupied Kashmir in Pakistan are against the border barrier since Kashmir is a disputed territory.
The Iran-Pakistan barrier wall is 700 kilometer long, which Iran claims is to stop the flow of illegal border crossings, stem the flow of drugs and prevent terror attacks from Pakistan. However, the Provincial Assembly of Balochistan, whose lands straddle the border region strongly opposes the construction of the wall and maintains that the wall would create problems for the Baloch people by dividing their community politically and socially, with their trade and social activities being seriously impeded. Leader of the Opposition, Kachkol Ali, said the governments of the two countries had not taken the Baloch into their confidence on this matter  and demanded that the construction of the wall be stopped immediately and he also appealed to the international community to help the Baloch people. Residents of the Sorap locality in the Mand area of western Mekran region in Balochistan province rely on edible goods from Iran for their livelihood but Iranian border security forces vacate the town . According to BBC, "The Balochistanis, who live on both sides of the border and in the area where both countries neighbour Afghanistan, have had their communities divided by the wall."
Due to Israel's specific situation of being at war and conflict with much of its Middle Eastern environment, border barriers have been and remain an issue of major military (and often also political) concern:
- Jerusalem: During the 1950s and 1960s a fortified separation barrier also divided much of Jerusalem to separate Jordanian and Israeli-controlled sectors of the city. It was pulled down in the immediate aftermath of the 1967 Six Day War, when the eastern part of the city came under Israeli rule. Currently, the route of the West Bank barrier in Jerusalem cuts off residents of the Jerusalem municipality from Jerusalem proper.
- Lebanon and Syria: Israel's borders with Lebanon and Syria have sophisticated security barriers, including electronic surveillance and warning systems. The barrier along the Lebanese border follows the lines of the 1949 Armistice and was laid down in coordination with the UN, the government anxious to make clear that it had withdrawn completely from Lebanese territory (excepting the ongoing dispute on the Shaba Farms).
- The barrier on the Syrian border on the Golan Heights reflects the situation in the aftermath of the Yom Kippur War, when Israel retained the territory conquered in 1967 except for handing back the town of Kuneitra. The Syrian government has repeatedly demanded the return of the entire Golan, but has made no specific issue of Israel erecting a security barrier along the border as it presently stands.
- Egypt: Israel saw no need to fortify the Sinai Desert border with Egypt after the 1979 Israeli-Egyptian Peace Treaty. The fence along that border was always more a marker than an effective barrier, and has become rusty and swamped by shifting sand dunes. The porous border has become the scene of extensive drug trafficking and the smuggling of women, typically from Third World and East European countries, who are subsequently forced into prostitution, as well as the entry of various refugees, asylum-seekers and illegal immigrants from various African countries, notably Sudanese fleeing the genocide in Darfur. There were also isolated cases of infiltration by armed terrorists, and apprehension that they would increase. In December 2005 the government of Israel proposed building a £200 million security barrier along the Egyptian border, but as of late 2007 the funds have not been actually allocated.
- Jordan: The border of Israel's territory with Jordan, mostly in the Negev Desert along the Arabah, is considered the most peaceful of the country's borders, due to traditional good relations with Jordan's Hashemite Dynasty. In March 2004, Israel and Jordan commenced a joint project to build a desert science centre on their shared border. They have taken down a stretch of the border fence between the Red Sea and the Dead Sea for the campus.
As well as the in the Negev, Israel also controls the West Bank's border with Jordan in the Jordan Valley. Along this border there is a security barrier with a two-way aim, designed to stop both infiltration from Jordan into the Israeli-controlled territory and the passage of West Bank Palestinians, uncontrolled by Israeli officials, into Jordan.
- The Israeli Gaza Strip barrier involves a security barrier along Israel's 1949 Armistice lines. There is also the security barrier along the Gaza Strip's border with Egypt (see Philadelphi Route), erected when Israel was in direct military control of the area. Though Israeli forces were withdrawn in 2005, the Government of Israel retains a declared interest in the area, especially due to alleged large-scale smuggling of arms from Sinai into the Strip, and insists upon the Egyptians and Palestinians maintaining intact the barrier between their respective territories – such insistence backed by sometimes open threats to otherwise resume direct Israeli military control.
South Korea has constructed a border barrier between its territory and North Korea to obstruct any southward movement by the army of North Korea. The border features:
- Military Demarcation Line
- Korean Demilitarized Zone
The United Nations has constructed a demilitarized zone to stop Iraq from re-invading Kuwait; Kuwait plans to install a new border barrier as well.
The Moroccan Wall is an approximately 2,700 km-long structure, mostly a sand wall (or "berm"), running through the region of Western Sahara and the southeastern portion of Morocco. It acts as a barrier between the Moroccan-controlled areas (Southern Provinces) and the Polisario-controlled section of the territory - Free Zone or de facto the self-proclaimed Sahrawi Arab Democratic Republic that lies along its eastern and southern border.
In Belfast, Derry and other settlements in Northern Ireland, barriers called "peace lines" have been built to separate the two main communities. Their purpose is to minimize inter-communal violence between Irish nationalists/republicans (who mainly self-identify as Irish and/or Catholic) and unionists/loyalists (who mainly self-identify as British and/or Protestant). They were first built following the 1969 riots and beginning of the "Troubles". They have continued to be built and expanded since the Belfast Agreement of 1998. In 2008 a public discussion began about how and when the barriers could be removed. On 1 September 2011, Belfast City Council agreed to develop a strategy regarding the removal of peace walls. At the end of 2011 several local community initiatives resulted in several interface structures being opened for a trial period. In January 2012, the International Fund for Ireland launched a Peace Walls funding programme to support local communities who want to work towards beginning to remove the peace walls.
In September 2005, Pakistan stated it has plans to build a 1,500-mile (2,400 km) fence along its border with Afghanistan to prevent Islamic insurgents and drug smugglers slipping between the two countries. Former Pakistani President Pervez Musharraf has subsequently offered to mine the border as well.
There is an electronic security barrier (ex-"Iron Curtain") along the old Soviet border. Also, a security barrier is on the border of Russia with Norway, Finland, China, Mongolia and North Korea. There is no barrier on Russian territory along the border with Estonia, Latvia, Belarus, or Ukraine, but there are some barriers on Estonian, Latvian and Ukrainian territory along the Russian border. It was reported in 2005 that the Russian government was considering the construction of a security barrier along its internal border with Chechnya as part of its efforts to combat terrorism.
Saudi Arabia has begun construction of a border barrier or fence between its territory and Yemen to prevent the unauthorized movement of people and goods into and out of the Kingdom. The Yemenis have been a source of trouble for the Saudis for many years. The difference between the countries economies means that many Yemenis head northward into Saudi Arabia. Saudi Arabia does not however, have a barrier with its other GCC neighbours, as their economies are generally well off.
- Saudi-Yemen barrier
In 2006 Saudi Arabia proposed plans for the construction of a security fence along the entire length of its desert border of 900 kilometres (560 mi) with Iraq in a multi-million dollar project to secure the Kingdom's borders in order to improve internal security, control illegal immigration and bolster its defences against external threats.
- Saudi-Iraq barrier
As of July 2009 it was reported that Saudis will pay $3.5 billion for security fence.
|“||Concern is growing in South Africa over the country's use of a lethal, 3,300 volt one amp electrified fence on its borders with Mozambique and Zimbabwe. According to a report recently published by the South African Catholic Bureau for Refugees, the fence has caused more deaths in three years than the Berlin Wall did in its entire history. Local people call the fence the 'Snake of Fire'. There have been calls by South African church leaders over the past months for the fence to be switched off permanently. Most of its victims have been women and children fleeing the war in Mozambique. The Berlin Wall resulted in 80 deaths over 28 years. Official figures provided by the South African Defence Force (SADF) indicate that 89 people were electrocuted at the fence between August 1986 and August 1989. Church leaders dispute these figures, and claim that the true figure is nearer 200 each year.||”|
A treaty signed on December 9, 2002 by the presidents of three countries - South Africa, Mozambique, and Zimbabwe allowed for the fence to be torn down in order to open the ancient elephant migration route between South Africa and Mozambique which was disrupted by the fence. The Great Limpopo Transfrontier Park of 35,000 square kilometres (14,000 sq mi) will connect the parks of three countries: South Africa's Kruger National Park, Mozambique's Limpopo National Park, and Zimbabwe's Gonarezhou National Park.
In 2005 it was reported that only a relatively small portion of the high-security border fence separating South Africa's Kruger National Park with Zimbabwe's Gonarezhou Park has been removed. Security concerns, especially about illegal immigrants and the smuggling of weapons and four-wheel-drive vehicles, have been hindering the removal of more sections of the border fence between the Kruger and Limpopo parks.

Even though both the United Kingdom and Spain are part of the European Union, the border fence separating Gibraltar and Spain is still relevant since Gibraltar is not part of the Schengen Area and is outside of the customs union and VAT area. The border crossing is open twenty-four hours a day to facilitate customs collection by Spain.
Thailand plans to build a concrete fence along parts of its border with Malaysia to keep Muslim militants and dual citizens from crossing Thailand's southern border with Malaysia.

The United States has constructed a border barrier along 130 kilometres (81 mi) of its border with Mexico of 3,169 kilometres (1,969 mi) to prevent unauthorized immigration into the United States and to deter smuggling of contraband, particularly illegal drugs. There has been legislation in the U.S. Congress on lengthening the barrier, but progress has been slow, both from lobbying and lack of funding.

- Between Russia (Soviet Union) and Finland/Norway there was a fence on the Soviet side along the entire border (more than 1000 km) during the Cold war. Along the Finnish border it was not so well guarded since Finland agreed to send back all Russians who escaped. The fence was located a few km from the border, and still partly remains, even though the border controls are open now. It is still forbidden according by Russian law to pass the border except through a border station.

Why are they doing that, are they mad, they are spending billions of rupees. Because it is effective. Let's fence this border so that this blame game is killed once for ever."
