The economy of Angola remains heavily influenced by the effects of four decades of conflict in the last part of the 20th century, the war for independence from Portugal (1961–75) and the subsequent civil war (1975–2002). Poverty since 2002 is reduced over 50% and a third of the population relies on subsistence agriculture. Since 2002, when the 27-year civil war ended, government policy prioritized the repair and improvement of infrastructure and strengthening of political and social institutions. During the first decade of the 21st century, Angola's economy was one of the fastest-growing in the world, with reported annual average GDP growth of 11.1 percent from 2001 to 2010. High international oil prices and rising oil production contributed to strong economic growth, although with high inequality, at that time. 2022 trade surplus was $30 billion, compared to $48 billion in 2012.
The economy of Alberta is the sum of all economic activity in Alberta, Canada's fourth largest province by population. Alberta's GDP in 2018 was CDN$338.2 billion.
The economy of Brunei, a small and wealthy country, is a mixture of foreign and domestic entrepreneurship, government regulation and welfare measures, and village traditions. It is almost entirely supported by exports of crude oil and natural gas, with revenues from the petroleum sector accounting for over half of GDP. Per capita GDP is high, and substantial income from overseas investment supplements income from domestic production. The government provides for all medical services and subsidizes food and housing. The government has shown progress in its basic policy of diversifying the economy away from oil and gas. Brunei's leaders are concerned that steadily increased integration in the world economy will undermine internal social cohesion although it has taken steps to become a more prominent player by serving as chairman for the 2000 APEC forum. Growth in 1999 was estimated at 2.5% due to higher oil prices in the second half.
The economy of Colombia is the fourth largest in Latin America as measured by gross domestic product and the third-largest economy in South America. Colombia has experienced a historic economic boom over the last decade. Throughout most of the 20th century, Colombia was Latin America's 4th and 3rd largest economy when measured by nominal GDP, real GDP, GDP (PPP), and real GDP at chained PPPs. Between 2012 and 2014, it became the third largest in Latin America by nominal GDP. As of 2024, the GDP (PPP) per capita has increased to over US$19,000, and real gross domestic product at chained PPPs increased from US$250 billion in 1990 to nearly US$800 billion. Poverty levels were as high as 65% in 1990, but decreased to under 30% by 2014, and 27% by 2018. They decreased by an average of 1.35% per year since 1990.
The economy of Equatorial Guinea has traditionally been dependent on commodities such as cocoa and coffee, but is now heavily dependent on petroleum due to the discovery and exploitation of significant oil reserves in the 1980s. In 2017, it graduated from "Least Developed Country" status, one of six Sub-Saharan African nations that managed to do so.
The economy of Kazakhstan is the largest in Central Asia in both absolute and per capita terms. As of 2023, Kazakhstan attracted more than US$370 billion of foreign investments since becoming an independent republic after the dissolution of the former Soviet Union.
The gross domestic product (GDP) of Niger was $16.617 billion US dollars in 2023, according to official data from the World Bank. This data is based largely on internal markets, subsistence agriculture, and the export of raw commodities: foodstuffs to neighbors and raw minerals to world markets. Niger, a landlocked West African nation that straddles the Sahel, has consistently been ranked on the bottom of the Human Development Index, at 0.394 as of 2019. It has a very low per capita income, and ranks among the least developed and most heavily indebted countries in the world, despite having large raw commodities and a relatively stable government and society not currently affected by civil war or terrorism. Economic activity centers on subsistence agriculture, animal husbandry, re-export trade, and export of uranium.
The economy of Qatar is one of the highest in the world based on GDP per capita, ranking generally among the top ten richest countries on world rankings for 2015 and 2016 data compiled by the World Bank, the United Nations, and the International Monetary Fund (IMF). The country's economy has grown despite sanctions by its neighbors, Saudi Arabia and the United Arab Emirates. Mainly because the country exports primarily to Japan, South Korea, India and China, making the sanctions effectively redundant as neither Saudi Arabia nor the United Arab Emirates have imposed trading penalties such as tariffs or embargoes on any of these countries for trading with Qatar, or offering incentives such as discounts for their own energy exports to reduce Qatari exports.
The economy of Saudi Arabia is the second-largest in the Middle East and the seventeenth-largest in the world. The Saudi economy is highly reliant on its petroleum sector. Oil accounts on average in recent years for approximately 40% of Saudi GDP and 75% of fiscal revenue, with substantial fluctuations depending on oil prices each year.
The economy of Senegal is driven by mining, construction, tourism, fishing and agriculture, which are the main sources of employment in rural areas, despite abundant natural resources in iron, zircon, gas, gold, phosphates, and numerous oil discoveries recently. Senegal's economy gains most of its foreign exchange from fish, phosphates, groundnuts, tourism, and services. As one of the dominant parts of the economy, the agricultural sector of Senegal is highly vulnerable to environmental conditions, such as variations in rainfall and climate change, and changes in world commodity prices.
The economy of Trinidad and Tobago is the third wealthiest in the Caribbean and the fifth-richest by GDP (PPP) per capita in the Americas. Trinidad and Tobago is recognised as a high-income economy by the World Bank. Unlike most of the English-speaking Caribbean, the country's economy is primarily industrial, with an emphasis on petroleum and petrochemicals. The country's wealth is attributed to its large reserves and exploitation of oil and natural gas.
The Organization of the Petroleum Exporting Countries is a cartel enabling the co-operation of leading oil-producing and oil-dependent countries in order to collectively influence the global oil market and maximize profit. It was founded on 14 September 1960, in Baghdad by the first five members which are Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. The organization, which currently comprises 12 member countries, accounted for an estimated 30 percent of global oil production. A 2022 report further details that OPEC member countries were responsible for approximately 38 percent of it. Additionally, it is estimated that 79.5 percent of the world's proven oil reserves are located within OPEC nations, with the Middle East alone accounting for 67.2 percent of OPEC's total reserves.
The economy of the Middle East is very diverse, with national economies ranging from hydrocarbon-exporting rentiers to centralized socialist economies and free-market economies. The region is best known for oil production and export, which significantly impacts the entire region through the wealth it generates and through labor utilization. In recent years, many of the countries in the region have undertaken efforts to diversify their economies.
Russia's energy policy is presented in the government's Energy Strategy document, first approved in 2000, which sets out the government's policy to 2020. The Energy Strategy outlines several key priorities: increased energy efficiency, reducing the impact on the environment, sustainable development, energy development and technological development, as well as improved effectiveness and competitiveness. Russia's greenhouse gas emissions are large because of its energy policy. Russia is rich in natural energy resources and is one of the world's energy superpowers. Russia is the world's leading net energy exporter, and was a major supplier to the European Union until the Russian invasion of Ukraine. Russia has signed and ratified the Kyoto Protocol and Paris Agreement. Numerous scholars posit that Russia uses its energy exports as a foreign policy instrument towards other countries.
The Japan Crude Cocktail (JCC) is the informal nickname given to the pricing index of Crude Oil used in most East Asian countries. The JCC is the average price of customs-cleared crude oil imports into Japan and is published by the Petroleum Association of Japan. The official name of the JCC is the Japan Customs-cleared Crude Oil Price. The valuation of the JCC closely reflects the market state of supply and demand. Clear fluctuations in JCC pricing can be linked to distinct events such as the 2007-08 Global Financial Crisis and the 2011 Fukushima Disaster.
The economic history of Ecuador covers the development of Ecuador's economy throughout its history, beginning with colonization by the Spanish Empire, through independence and up to the 21st century.
The 1970s energy crisis occurred when the Western world, particularly the United States, Canada, Western Europe, Australia, and New Zealand, faced substantial petroleum shortages as well as elevated prices. The two worst crises of this period were the 1973 oil crisis and the 1979 energy crisis, when, respectively, the Yom Kippur War and the Iranian Revolution triggered interruptions in Middle Eastern oil exports.
Iran is an energy superpower and the petroleum industry in Iran plays an important part in it. In 2004, Iran produced 5.1 percent of the world's total crude oil, which generated revenues of US$25 billion to US$30 billion and was the country's primary source of foreign currency. At 2006 levels of production, oil proceeds represented about 18.7% of gross domestic product (GDP). However, the importance of the hydrocarbon sector to Iran's economy has been far greater. The oil and gas industry has been the engine of economic growth, directly affecting public development projects, the government's annual budget, and most foreign exchange sources.
OQ, formerly known as Oman Oil Company, is an energy investment company headquartered in Muscat, Oman. It is a wholly owned subsidiary of the Government of Oman through the Oman Investment Authority.
Since becoming an independent country, Ivory Coast has transitioned from an economy dominated by agriculture—coffee and cocoa in particular—to a diversified economy with a large service sector. From 1960 to 1976, government policy focused on investing revenues from agricultural export into infrastructure. From 1976 to 1980, factors such as a boom-bust in coffee and cocoa prices, over-investment funded by foreign debt, and a devaluation of the US Dollar led Ivory Coast to the brink of financial crisis. Decreased revenues from coffee and cocoa exports continued into the 80's and early 90's, increasing the burden of foreign debt and eventually requiring lender negotiation. This resulted in the privatization of many state-owned enterprises with mixed levels of success. In 1994, the economy began a comeback due to devaluation of the CFA franc, increased export revenues, financial reforms, and debt rescheduling. Since then the economy has been impacted by and rebounded from political crises such as the 1999 coup d'état and the 2011 election crisis.
