Three Gorges Dam
EnergyThe world's largest hydropower station by installed capacity, at 22.5 GW, and the main flood-control structure on the Yangtze.
New Zealand occupied the German protectorate of Western Samoa at the outbreak of World War I in 1914. It continued to administer the islands as a mandate and then as a trust territory until 1962, when the islands became the first Polynesian nation to reestablish independence in the 20th century. The country dropped the "Western" from its name in 1997.
The National Infrastructure Index maps the physical assets national life runs on — power stations and grids, water systems, ports, railways and airports, data networks, payment systems and launch sites. Each asset is placed in a Strategic Infrastructure capability group, so it can be read against the ratings in the National Capability index above.
Assets are chosen for how much of the economy and state depends on them and how hard they would be to replace. Each card records what the asset is, the category it belongs to, what it does and where it is.
Example assets. These twenty cards are modelled on China's most critical infrastructure and show on every nation page until each nation's own assets are mapped.

The National Development Index tracks the events that move a nation's capability — policy decisions, technological milestones, economic turns and external shocks — and places each one on the record with the date it happened and what followed from it. It is the narrative counterpart to the indices: where a rating says where Samoa stands, the index says how it arrived there.
Recent developments cover the current cycle, close enough that their consequences are still unfolding. Historical developments are the inflection points behind the present position — the decisions and events a reader needs in order to read the ratings above in context.
Austronesian-speaking Lapita voyagers from Island Melanesia reached the Samoan archipelago, with the earliest human remains dated to roughly 2,900 to 3,500 years ago. This settlement founded the population and the fa'a Samoa cultural order that has endured ever since.
The ancient Malietoa lineage expelled Tongan overlordship, becoming one of the two principal royal families of Samoa alongside the Sā Tupua. The four paramount titles descending from these lines still form the apex of the matai system.
The Dutch navigator Jacob Roggeveen sighted the Samoan islands, opening European awareness of the archipelago. Contact nevertheless remained limited for over a century.
The French explorer visited Samoa and gave the group the name by which Europeans knew it for decades. His voyage extended European mapping of the central Pacific.
Captain Benjamin Vanderford's vessel was the first known American trading ship to call at Samoa, followed by the Nantucket whaler Maro in 1824. Visits by American traders and whalers seeking water, firewood and provisions, and later local crewmen, were important to Samoa's early commercial development; the last recorded whaler called in 1870.
Arriving from the Cook Islands and Tahiti, Williams launched sustained missionary activity in Samoa. From the 1830s British missionaries, whalers and traders arrived in numbers, and Christianity became foundational to Samoan society.
Germany, Britain and the United States had each armed, trained and at times supported rival Samoan factions through an eight-year civil war, and by March 1889 warships from all three powers had converged on Apia harbour with a wider war seeming imminent. A massive storm on 15 March 1889 destroyed or damaged the vessels, ending the military stand-off and forcing a diplomatic resolution to what became known as the Samoan crisis.
Forces loyal to Prince Tanu, backed by landing parties from four British and American warships, were besieged by larger rebel forces loyal to Mataʻafa Iosefo before the rebels were defeated. American and British warships, including the USS Philadelphia, shelled Apia on 15 March 1899, prompting the powers to seek a settlement.
Signed in Washington on 2 December 1899 with ratifications exchanged on 16 February 1900, the convention followed renewed fighting between rival Samoan factions backed by the three powers earlier that year and partitioned the archipelago: Germany took the larger western islands, which became German Samoa, and the United States the eastern islands, later American Samoa. Britain vacated its claims in return for the end of German rights in Tonga, the Solomon Islands south of Bougainville and alignments in West Africa.
Germany governed the western Samoan islands from 1900 to 1914 on the principle that there was only one government in the islands, abolishing the Tupu and alii sili and appointing two Fautua advisers instead. The traditional governments of Tumua and Pule were silenced and all land and title decisions passed to the colonial governor.
Germans introduced commercial sugarcane production during the colonial period, adding to an economy previously dominated by copra. German firms had earlier monopolised copra and cocoa processing on Upolu.
The eruption was the most recent major volcanic activity in Samoa, following earlier events at Mata o le Afi in 1902 and Mauga Afi in 1725. Savaiʻi remains the only volcanically active island in the group.
When the non-violent Mau a Pule resistance movement arose on Savai'i, Solf banished its leader, the orator chief Lauaki Namulauʻulu Mamoe, to Saipan in the German Northern Marianas. Lauaki died en route back to Samoa in 1915, but the movement seeded the later Mau independence campaign.
An expeditionary force landed unopposed on Upolu on 29 August 1914, taking control from the German colonial administration at Britain's request. New Zealand went on to administer the territory under League of Nations and then United Nations trusteeship until 1962.
The ship arrived from Auckland on 7 November 1918 and within a week pneumonic influenza was epidemic on Upolu and then throughout the territory; 90% of the population was infected and roughly a fifth died, including 30% of adult men. A 1919 Royal Commission confirmed the source, and the disaster destroyed Samoan confidence in New Zealand's competence, with some chiefs asking for transfer to American or British rule.
With natural rubber values falling at the end of World War I, New Zealand encouraged Samoan growers to plant bananas for the large New Zealand market. Bananas and copra have since each yielded roughly 13,000 to 15,000 tonnes a year.
New Zealand's wartime occupation was formalised as a League of Nations Class C mandate in 1920, creating the Territory of Western Samoa, which New Zealand then administered as a UN trust territory until independence in 1962. From 1919 the territory was run by a Department of External Affairs created specially for New Zealand's island territories, renamed the Department of Island Territories in 1943.
Police opened fire and used a machine gun on a peaceful Mau movement march in Apia on 28 December 1929, killing paramount chief Tupua Tamasese Lealofi III and 10 others and wounding about 50. The killings galvanised Samoa's independence movement rather than suppressing it.
On 13 January 1930 the organisation was outlawed; as many as 1,500 Mau men took to the bush, pursued by 150 marines and seamen from HMS Dunedin, 50 military police and a seaplane, with villages raided at night with fixed bayonets. In March, mediation by local Europeans and missionaries led Mau leaders to meet New Zealand's Minister of Defence and agree to disperse.
Following Labour's victory in New Zealand's 1935 general election, a goodwill mission to Apia in June 1936 recognised the Mau as a legitimate political organisation and allowed Olaf Nelson to return from exile. In September 1936 Samoans voted for the first time for members of the advisory Fono of Faipule, the Mau winning 31 of 39 seats.
New Zealand's League of Nations mandate became a United Nations trusteeship, continuing its administration under international supervision. The trusteeship framework set the path towards eventual independence.
The constitution, which came into force with independence in 1962, built on the British parliamentary model while accommodating Samoan customary institutions such as the matai system. It remains the country's basic law.
New Zealand's Parliament passed the Western Samoa Act on 24 November 1961, terminating the Trusteeship Agreement and creating the Independent State of Western Samoa with effect from 1 January 1962, making the country the first small Pacific Island state to become independent in the 20th century. Fiamē Mataʻafa Faumuina Mulinuʻu II became the first prime minister, Tupua Tamasese Meaʻole and Malietoa Tanumafili II became joint heads of state for life, and Samoa and New Zealand signed a Treaty of Friendship later that year.
Concluded later in its independence year, the treaty committed New Zealand to consider any Samoan request for assistance. It remains the basis of Samoa's informal defence relationship with New Zealand.
Admission on 28 August 1970 tied the new state into the Commonwealth's diplomatic and technical networks. It complemented later membership of the United Nations and the Pacific Islands Forum.
Excavation of a Lapita site at Mulifanua yielded Samoa's earliest human remains, dated to between about 2,900 and 3,500 years ago, and the results were published in 1974. The find anchored scientific dating of Samoan settlement and supported wider research into Polynesian genetics, linguistics and anthropology.
The state corporation was created to run ferry services between Upolu and Savai'i. It provides the essential internal transport link between the two main islands.
Then known as Western Samoa, the country was admitted on 15 December 1976 and asked to be referred to at the UN as the Independent State of Samoa. It had joined the Commonwealth of Nations six years earlier, in 1970.
The country's main post-secondary institution opened, giving Samoa domestic tertiary capacity. A 2012 UNESCO report recorded adult literacy at 99 per cent.
Seine Stowers took gold in the women's 77kg category and John Lautafi Tafi silver in the men's 71kg category, with his clean-and-jerk lift setting a Games record. Samoa's 39-member delegation finished third among Pacific nations at the games, which closed on 2 August 2026.
A delegation from the International Institute for Democracy and Electoral Assistance joined the commission for consultations beginning in mid-August 2026 on whether eligible voters overseas could cast ballots online. Any change would open a new channel for the Samoan diaspora, a significant contributor to the economy through remittances, to take part in national elections.
Ministers meeting in Suva on 7 August 2026 could not reach consensus after China fired a nuclear-capable missile that splashed down about 1,900 kilometres north-west of Samoa in July. Samoa was represented by the chief executive of its foreign ministry, Peseta Noumea Simi, rather than a minister.
The former prime minister and opposition leader said on 13 July 2026 that the government's inquiry into alleged treason and defamation involving him and two senior members of parliament had stalled for lack of evidence. Tuilaepa, who led Samoa for more than 20 years before losing power in 2021, remained a vocal critic of the FAST government.
Prime minister Laʻauli Leuatea Schmidt publicly rebuked the students over the brawl, while the university's vice-chancellor urged them to recognise that a university education is a privilege that comes with responsibilities. The incident renewed debate over discipline and safety on Samoan campuses.
The government cited unresolved internal divisions when it withdrew support in late July 2026, a move the opposition warned could prompt a World Rugby ban, though World Rugby denied issuing any ultimatum. Prime minister Laʻauli Leuatea Schmidt's administration went on to help launch a rival rugby union days later.
Supplies of key drugs to treat type 2 diabetes and high blood pressure, along with children's paracetamol, ran critically low by June 2026. The hospital began rationing remaining stock to manage the shortage.
Joseph Vaa and Steve Tofa admitted on Vietnamese television to shooting Lorenzo Lemalu, leader of the so-called Coconut Cartel, outside a restaurant on 21 May 2026. The pair, who could face the death penalty in Vietnam, were charged amid a wider crackdown that had produced 20 drug raids in Samoa by early June.
The New Zealand government agreed on 6 October 2025 to pay about $3.6 million over the 2024 grounding and sinking of the naval vessel off Samoa's coast. A precautionary exclusion zone around the wreck, reduced to two kilometres in February 2025, remained in force.
Schmidt was inaugurated on 16 September 2025 after FAST won 30 of 51 seats in the 29 August general election, defeating incumbent prime minister Fiamē Naomi Mataʻafa, whose new Samoa Uniting Party took only three seats. Fiamē's government had collapsed in May 2025 after parliament voted down her budget.
The framework applies ocean zoning across the entire exclusive economic zone, designating fully protected marine protected areas alongside managed-use zones. Its adoption included nine new fully protected areas covering 36,000 km2.
After Mataʻafa dismissed Schmidt as FAST leader and agriculture minister over corruption charges, she was expelled from the party. FAST under Schmidt won the ensuing snap election and he replaced her as prime minister.
Her FAST party narrowly won the 2021 election and she was sworn in on 24 May 2021, though only in July did the Supreme Court rule the swearing-in legal. The transition ended Tuilaʻepa Saʻilele Malielegaoi's 22-year premiership and nearly four decades of Human Rights Protection Party rule.
The state utility set a goal of generating all of the country's power from renewable sources by 2021. The target reflected Samoa's exposure to fuel import costs and climate risk.
The count rose from 194,320 in the 2016 census. Samoans make up about 96 per cent of residents, with dual Samoan New Zealanders a further 2 per cent.
The outbreak began in October 2019 and by early January had caused 83 deaths and over 4,460 cases, mostly among children under four. It exposed weaknesses in immunisation coverage and damaged tourism.
Article 1 was changed to declare Samoa a Christian nation founded on God the Father, the Son and the Holy Spirit. The amendment gave constitutional standing to the country's dominant faith.
The legislature chose Sualauvi II as O le Ao o le Malo in 2017 and re-elected him in 2022. The office had passed to elected terms after the death of the last life head of state.
Samoa joined the UN treaty banning nuclear weapons, aligning with Pacific disarmament diplomacy. The step reinforced its profile in multilateral security forums.
The reclassification in 2014 marked Samoa's graduation in international economic categorisation. GDP in purchasing-power parity was estimated at $1.13 billion in 2017, with a labour force of about 50,700.
At the end of December 2011 Samoa jumped forward a day, omitting Friday 30 December and moving the International Date Line to its east; the previous zone, set on 4 July 1892, had aligned with Californian traders. The change put Samoa three hours ahead of Sydney rather than 21 behind, to ease business with Australia and New Zealand. Daylight saving time was discontinued in October 2021.
On 7 September 2009 Samoa changed the rule of the road to align with Australia, New Zealand and most Commonwealth countries, home to large Samoan communities. It was the first country in the 21st century to make the switch.
The tsunami was one of the natural disasters that periodically disrupt Samoa's tourism-dependent economy, alongside cyclones. Such shocks, with the 2019 measles outbreak and COVID-19, make the sector highly volatile.
Clark's apology, delivered in Samoa, covered New Zealand's responsibility for allowing the 1918 influenza outbreak to spread unchecked and for the 1929 Black Saturday killings. It marked a formal reckoning with the legacy of New Zealand's colonial administration of the territory.
The change from Western Samoa to Samoa took effect on 4 July 1997, adopting the name the country had used at the United Nations since joining in 1976. American Samoa protested, arguing the change diminished its own distinct identity.
The franchise was extended to all adults, ending restriction of voting to matai. Candidacy for the Samoan seats, however, remained limited to holders of matai titles.
Samoa signed on 28 September 1984, ratified on 14 August 1995, and the convention entered into force for it on 13 September 1995. Membership made the country a party to international management of marine resources and secured its rights over a vast ocean territory.
The head of state, a Baháʼí convert, dedicated the temple completed that year 8 km from Apia. Its construction reflected religious diversity within an overwhelmingly Christian nation.
New Zealand occupied the German protectorate of Western Samoa at the outbreak of World War I in 1914. It continued to administer the islands as a mandate and then as a trust territory until 1962, when the islands became the first Polynesian nation to reestablish independence in the 20th century. The country dropped the "Western" from its name in 1997.

The economy of Samoa has traditionally been dependent on development aid, family remittances from overseas, agriculture, and fishing. The country is vulnerable to devastating storms. Agriculture employs roughly two-thirds of the labor force and furnishes 90% of exports, featuring coconut cream, coconut oil, and copra. The manufacturing sector mainly processes agricultural products. One factory in the Foreign Trade Zone employs 3,000 people to make automobile electrical harnesses for an assembly plant in Australia. Tourism is an expanding sector accounting for 25% of GDP; 122,000 tourists visited the islands in 2007. In late September 2009, an earthquake and the resulting tsunami severely damaged Samoa, and nearby American Samoa, disrupting transportation and power generation, and resulting in about 200 deaths. In December 2012, extensive flooding and wind damage from Tropical Cyclone Evan killed four people, displaced over 6,000, and damaged or destroyed an estimated 1,500 homes in Samoa's Upolu island. The Samoan Government has called for deregulation of the financial sector, encouragement of investment, and continued fiscal discipline, while at the same time protecting the environment. Observers point to the flexibility of the labor market as a basic strength for future economic advances. Foreign reserves are in a relatively healthy state, the external debt is stable, and inflation is low.
