Equatorial Guinea and Its Neighbours in Central Africa

EQUATORIAL GUINEA · NEIGHBOURHOOD

Equatorial Guinea is a Central African country of about 1.9 million people whose mainland strip lies between Cameroon and Gabon and whose islands sit out in the Gulf of Guinea, within reach of Nigeria and São Tomé and Príncipe. This guide follows its land borders, sea boundaries, regional blocs, oil and gas, migration and trade, with every figure dated as of October 2026 or to the year shown.

Equatorial Guinea in Plain English

Equatorial Guinea covers 28,052 square kilometres (10,831 square miles), made up of a 26,000 square kilometre mainland region, the island of Bioko with 2,017, Annobón with 17 and Corisco with 15, according to the government’s information page. The government calls Bata the continental capital and Malabo, on Bioko, the island capital.

The same page says the mainland region borders Cameroon to the north, Gabon to the east and south, and the Gulf of Guinea to the west. The government’s account of the flag adds that its blue stands for the sea that joins the continental and island zones, while the six stars on the coat of arms, approved on 12 October 1968, stand for the country’s territories.

The World Bank, the global development lender, counts 1.94 million people in Equatorial Guinea in 2025 and an economy of US$12.8 billion, about US$6,600 per person. Real output fell 5.8% in 2025 after a 0.4% rise in 2024 and a 7.4% fall in 2023, in World Bank data as of October 2026.

President Teodoro Obiang Nguema Mbasogo has held the presidency since 3 August 1979, the government says, and Vice-President Teodoro Nguema Obiang Mangue, his son, chaired government meetings in Malabo on 28 October 2026. Manuel Osa Nsue is prime minister in charge of administrative coordination, and he presented the 2027 state budget to the Chamber of Deputies on 24 September 2026.

The Rio Times Equatorial Guinea explainer covers the politics, the oil story and the new capital in depth. This guide looks outward at the neighbours instead, and it sits beside the wider Rio Times Africa coverage.

Gabon, the Southern Neighbour

Gabon lies to the east and south of the mainland and is the larger economy, with 2.6 million people and US$21.4 billion of output in 2025, about 1.7 times Equatorial Guinea’s. Per person that is about US$8,300 in Gabon against US$6,600 in Equatorial Guinea, in World Bank data.

Gabon’s president, Brice Clotaire Oligui Nguema, is listed on the presidency’s website as President of the Republic, Head of State and Head of Government, as of October 2026. The Rio Times has a separate guide to Gabon in Central Africa, and the two countries sit in the same two regional blocs.

The best-known dispute between them concerned three small islands, Mbanié, Cocotiers and Conga, which both countries claimed. The two governments signed a Special Agreement in 2016 that took effect in March 2020, and on 5 March 2021 they asked the International Court of Justice (ICJ), the United Nations’ top court, to decide which legal titles had the force of law.

The ICJ delivered its judgment on 19 May 2025, and Gabon’s presidency, which received the ruling on 28 May 2025, says it gave Equatorial Guinea sovereignty over the three islands on the basis of the 1900 treaty between France and Spain. The same statement says the maritime boundary between the two states remains to be determined, and the Court’s case page lists two separate opinions and two declarations by judges, a declaration by one judge ad hoc and a dissent by the other.

The two presidents agreed in Malabo on 4 June 2025 to create a joint committee of experts on the Mbanié dispute, and on 8 September 2025 Gabon’s president received the national commission that follows the judgment, with the presidency listing land-border delimitation, examination of sovereignty over Mbanié and a cooperation framework for the maritime border as next steps. On 9 July 2026 Gabon’s president received an African Union envoy following the dispute, which the presidency describes as part of the Union’s efforts to help the two states reach a lasting, peaceful and agreed resolution.

Cameroon, the Northern Neighbour

Cameroon is the giant to the north, with 29.9 million people and a US$58.9 billion economy in 2025, about 15 times Equatorial Guinea’s population and 4.6 times its output. Growth was 3.2% in 2025, but output per person was about US$2,000, less than a third of Equatorial Guinea’s, and the Rio Times has a separate Cameroon guide.

President Paul Biya, who was re-elected in the presidential election of 12 October 2025, received Equatorial Guinea’s vice-president in Yaoundé on 19 November 2025, according to the presidency’s website. The visitor carried a congratulatory message from President Obiang and encouraged Cameroonian entrepreneurs to look at investment opportunities in Equatorial Guinea, the presidency says.

Equatorial Guinea once took part in a legal fight between two of its neighbours, Cameroon and Nigeria, after the ICJ allowed it on 21 October 1999 to intervene in their case. The Court’s judgment of 10 October 2002 gave the Bakassi Peninsula to Cameroon and fixed the course of the sea boundary between Cameroon and Nigeria.

The United Nations Division for Ocean Affairs and the Law of the Sea lists maritime boundary agreements and related documents for Equatorial Guinea with Gabon, Nigeria and São Tomé and Príncipe, but none with Cameroon, as of October 2026. Equatorial Guinea’s own law of 6 March 1999 names the median line, the line equally distant from each coast, as its maritime boundary.

Nigeria and the Sea Neighbours

Nigeria lies across the Gulf of Guinea, with 237.5 million people and a US$290.8 billion economy in 2025, about 123 times Equatorial Guinea’s population and 23 times its output. Its president is Bola Ahmed Tinubu, according to the State House in Abuja, and the Rio Times covers the country in a separate West Africa guide.

Nigeria and Equatorial Guinea signed a treaty on their maritime boundary on 23 September 2000, and it entered into force on 3 April 2002, according to the United Nations ocean-affairs office. A protocol on implementing article 6.2 of the treaty was signed on 2 April 2002 and took effect on 29 June 2002.

São Tomé and Príncipe, an island nation with 240,254 people and a US$981 million economy, has about one-eighth of Equatorial Guinea’s population and one-thirteenth of its output. The government’s relief page places Annobón in the same volcanic chain as Bioko, São Tomé and Príncipe, and the Rio Times has a São Tomé and Príncipe explainer.

Equatorial Guinea and São Tomé and Príncipe signed a maritime boundary treaty on 26 June 1999. Other deals in the same waters include a joint petroleum development treaty between Nigeria and São Tomé of 21 February 2001 and a Gabon and São Tomé border agreement of 26 April 2001.

Both Equatorial Guinea and Nigeria are among the 12 member countries of the Gas Exporting Countries Forum, the club of major gas sellers whose eighth summit met in Moscow on 27 October 2026. Equatorial Guinea hosted the Forum’s summit in 2019, according to the Forum’s declaration.

CEMAC, ECCAS and the CFA Franc

The Economic and Monetary Community of Central Africa (CEMAC) groups six countries: Cameroon, the Republic of Congo, Gabon, Equatorial Guinea, the Central African Republic and Chad. Its own website says it was created in 1994 out of the ashes of an older customs union, and its Commission sits in Bangui, the capital of the Central African Republic.

CEMAC’s stated aims are a common market with free movement of people, goods, capital and services, and stable management of the common currency. Its website gives its area as 2,995,342 square kilometres (1.16 million square miles) and its population as 65,285,296, as of October 2026.

The common currency, the Central African CFA franc, is issued by the Bank of Central African States (BEAC), which has its headquarters in Yaoundé, Cameroon. The BEAC rate table shows 655.957 francs per euro and between 586 and 591 per US dollar, as of October 2026.

The BEAC’s outlook, reproduced by the Equatorial Guinean government on 16 January 2026, projects CEMAC growth of 4.6% in 2026 after 2.4% in 2025. Equatorial Guinea itself is projected to shrink in 2026, according to the International Monetary Fund (IMF).

The Economic Community of Central African States (ECCAS) is the wider club, with 11 members: the CEMAC six plus Angola, Burundi, Rwanda, the Democratic Republic of the Congo and São Tomé and Príncipe. Its treaty was signed in Libreville on 18 October 1983, a revised treaty was adopted on 18 December 2019 and took effect on 28 August 2020, and President Obiang is the current chair of its summit of heads of state and government.

In a message for the bloc’s 43rd anniversary, marked in Libreville on 19 October 2026, Obiang urged members to meet their financial commitments. The ECCAS Commission president, Ezéchiel Nibigira, listed insecurity, weak trade between members, poor infrastructure and obstacles to free movement among the problems.

Oil, Gas and a Shrinking Economy

The government itself says hydrocarbon production keeps falling as fields mature, and that oil prices in 2025 were below those of the year before. Presenting the 2027 budget on 24 September 2026, Prime Minister Osa Nsue said 2025 state revenue was 1.213 trillion CFA francs (US$2.1 billion at about 588 francs per US dollar, the BEAC’s indicative rate in late October 2026), of which oil gave about 77%.

The IMF, the global lender that reviews member economies each year, says in its 2025 Article IV report that the economy is projected to grow weakly in the medium term as hydrocarbon production declines. Its country page projects a 2.7% contraction in 2026 and inflation of 3.2%, as of October 2026.

The Gas Exporting Countries Forum’s country page, citing its 2024 statistical bulletin, lists proven natural gas reserves of 39 billion cubic metres (1.4 trillion cubic feet) and marketed production of 7 billion cubic metres (247 billion cubic feet). It shows exports of 5 billion cubic metres (177 billion cubic feet), all of it as liquefied natural gas.

On 28 October 2026 the Senate approved a new Hydrocarbons Bill by consensus of its parliamentary groups, after a second reading, to give the country a legal framework for oil operations that is, in the government’s words, sustainable and profitable. The minister delegate for national content, Domingo Mba Esono, said his ministry would present the contracts that govern the sector to the Senate and report voluntarily on how the law is applied.

People, Migration and Trade

The World Bank’s migration estimates, which come from United Nations data, count 248,930 international migrants in Equatorial Guinea in 2024, about 13% of its people. Gabon had 449,746, about 18% of its people, Cameroon 642,948 and Nigeria 1,403,281, and the counts cover migrants of every origin.

Free movement is a stated CEMAC aim, yet the ECCAS Commission president listed obstacles to the movement of people and goods among the bloc’s problems on 19 October 2026. The US travel advisory for Equatorial Guinea also warns that its borders may close without notice.

Equatorial Guinea launched an online visa platform, run by the firm VFS Global, on 1 July 2023, and the vice-president said on 28 October 2026 that only about 35,127 e-visas had been processed against an expected 200,000 a year. The government is studying a new contract with VFS Global to strengthen the system and has asked the departments involved for a report on its current state.

The government also said on 28 October 2026 that a revised contract with the construction firm Sogea-Satom, a subsidiary of the French group Vinci Construction, will finish three avenues in Ciudad de La Paz for 20 billion CFA francs (US$34 million) less than the earlier cost. Its news service describes the project as work on the new capital, and the vice-president said a payment schedule would be set.

Exports of goods and services were equal to 46.5% of output in Equatorial Guinea in 2025 and 55.5% in Gabon, against 13.1% in Cameroon and 13.3% in São Tomé and Príncipe, in World Bank data. Remittances reached US$690 million in Cameroon in 2024 and US$22.8 billion in Nigeria in 2025, and the World Bank has no recent figure for Equatorial Guinea or Gabon.

What It Means for US Readers

The US State Department rates Equatorial Guinea Level 2, Exercise Increased Caution, in an advisory dated 7 October 2025, citing crime and health. The advisory says police and military checkpoints are common and can restrict freedom of movement, and it recommends always travelling with a passport and valid visa.

The neighbours carry their own ratings in the department’s advisory feed: Cameroon Level 2 (15 May 2026), Gabon Level 2 (30 March 2026), São Tomé and Príncipe Level 2 (4 September 2026) and Nigeria Level 3, Reconsider Travel (12 June 2026). These are the levels and dates shown as of October 2026.

A presidential proclamation of 16 December 2025, in force from 1 January 2026, fully restricts the entry of Equatorial Guinean nationals into the United States, as it does for Chad and the Republic of Congo. It partially restricts Gabon and Nigeria, while Cameroon and São Tomé and Príncipe are not named in it.

The proclamation orders a report every 180 days on whether limits should continue, so the lists can change. For US companies and families the practical effect is that Equatorial Guinean partners cannot easily travel to the United States, while Americans can still go to Equatorial Guinea under the Level 2 advisory.

The US Census Bureau records US goods exports to Equatorial Guinea of US$84.1 million in 2025 and imports of US$95.6 million, small beside Cameroon (US$169.3 million and US$287.3 million) and Nigeria (US$6.78 billion and US$5.02 billion). The Equatorial Guinean government said on 22 October 2026 that its vice-president received the new US ambassador in Malabo and reviewed cooperation in oil, trade, finance, defence and security, as the Rio Times reported in its US envoy story.

What Is Not Known

The ICJ’s public pages list the judgment on the three islands but not how it will be carried out, and Gabon’s presidency says the maritime boundary and the follow-up on Mbanié are still being worked on. It is also unclear when the new Hydrocarbons Bill will be promulgated, since the Senate vote of 28 October 2026 is the latest step the government reports.

The United Nations ocean-affairs list shows no treaty on the sea boundary between Cameroon and Equatorial Guinea, and the public record does not make clear whether another form of agreement exists. The visa position for US visitors is also unclear, because the State Department’s country information page for Equatorial Guinea was last updated on 1 February 2019 while the government says an e-visa platform has operated since 1 July 2023.

The 180-day reviews could change the status of Equatorial Guinea, Gabon, Nigeria or Cameroon in the US entry lists. On the proclamation’s schedule the next report is due by 11 December 2026.
