Cambodia (also Kampuchea កម្ពុជា Cambodge), officially the Kingdom of Cambodia (ព្រះរាជាណាចក្រកម្ពុជា, Royaume du Cambodge), is a country located in the southern portion of the Indochina peninsula in Southeast Asia. It is in area, bordered by Thailand to the northwest, Laos to the northeast, Vietnam to the east and the Gulf of Thailand to the southwest. The sovereign state of Cambodia has a population of over 15 million. The official religion is Theravada Buddhism, practised by approximately 95 percent of the population. Cambodia's minority groups include Vietnamese, Chinese, Chams and 30 hill tribes. The capital and largest city is Phnom Penh, the political, economic and cultural centre of Cambodia. The kingdom is an elective constitutional monarchy with a monarch, currently Norodom Sihamoni, chosen by the Royal Council of the Throne as head of state. The head of government is the Prime Minister, currently Hun Sen, the longest serving non-royal leader in Southeast Asia, ruling Cambodia since 1985. In 802 AD, Jayavarman II declared himself king, uniting the warring Khmer princes of Chenla under the name "Kambuja". This marked the beginning of the Khmer Empire, which flourished for over 600 years, allowing successive kings to control and exert influence over much of Southeast Asia and accumulate immense power and wealth. The Indianised kingdom facilitated the spread of first Hinduism and then Buddhism to much of Southeast Asia and undertook many religious infrastructural projects throughout the region, including the construction of more than 1,000 temples and monuments in Angkor alone. Angkor Wat is the most famous of these structures and is designated as a World Heritage Site. In the fifteenth century, after the rebellion of Ayutthaya, which was formerly ruled by the Khmer Empire, Cambodia experienced the decline of power. Cambodia faced two increasingly powerful neighbors, Ayutthaya of Thailand and Nguyen dynasty of Vietnam, and marking the downturn of Cambodia's fate. In 1863, Cambodia became a protectorate of France, and later was incorporated into French Indochina of Southeast Asia. Cambodia gained independence from France in 1953. The Vietnam War extended into the country in 1965 with the expansion of the Ho Chi Minh Trail and establishment of the Sihanouk Trail. This led to the US bombing of Cambodia from 1969 until 1973. Following the Cambodian coup of 1970 which installed the right-wing pro-US Khmer Republic, the deposed King Sihanouk gave his support to his former enemies, the Khmer Rouge. With the support of the monarchy and North Vietnam, the Khmer Rouge emerged as a major power, taking Phnom Penh in 1975. The Khmer Rouge then carried out the Cambodian genocide from 1975 until 1979, when they were ousted by Vietnam and the Vietnamese-backed People's Republic of Kampuchea, supported by the Soviet Union, in the Cambodian–Vietnamese War. Following the 1991 Paris Peace Accords, Cambodia was governed briefly by a United Nations mission (1992–93). The UN withdrew after holding elections in which around 90 percent of the registered voters cast ballots. The 1997 factional fighting resulted in the ousting of the government by Prime Minister Hun Sen and the Cambodian People's Party, who remain in power . Cambodia is a member of the United Nations since 1955, ASEAN, the East Asia Summit, the WTO, the Non-Aligned Movement and La Francophonie. According to several foreign organisations, the country has widespread poverty, pervasive corruption, lack of political freedoms, low human development and a high rate of hunger. Cambodia has been described by Human Rights Watch's Southeast Asian Director, David Roberts, as a "relatively authoritarian coalition via a superficial democracy". Constitutionally a multi-party liberal democracy, the country is effectively governed under one-party rule as of 2018. While per capita income remains low compared to most neighboring countries, Cambodia has one of the fastest growing economies in Asia, with growth averaging 7.6 percent over the last decade. Agriculture remains the dominant economic sector, with strong growth in textiles, construction, garments and tourism leading to increased foreign investment and international trade. The United Nations designates Cambodia as a least developed country. The US World Justice Project's 2015 Rule of Law Index ranked Cambodia 125th out of 126 countries, far lower compared to other countries in the region.

Afghanistan (Pashto/Dari: افغانستان, Pashto: Dari: ), officially the Islamic Republic of Afghanistan, is a landlocked country situated at the confluence of Western, Central, and Southern Asia. Afghanistan is bordered by Pakistan to the east and south; Iran to the west; Turkmenistan, Uzbekistan, and Tajikistan to the north; and China to the northeast. Occupying it is a mountainous country with plains in the north and southwest. Kabul is the capital and largest city. The population is 32 million, mostly composed of ethnic Pashtuns, Tajiks, Hazaras and Uzbeks. Human habitation in Afghanistan dates back to the Middle Paleolithic Era, and the country's strategic location along the Silk Road connected it to the cultures of the Middle East and other parts of Asia. The land has historically been home to various peoples and has witnessed numerous military campaigns, including those by Alexander the Great, Mauryas, Muslim Arabs, Mongols, British, Soviets, and by the United States with allied countries. The land also served as the source from which the Kushans, Hephthalites, Samanids, Saffarids, Ghaznavids, Ghorids, Khaljis, Mughals, Hotaks, Durranis, and others have risen to form major empires. The political history of the modern state of Afghanistan began with the Hotak and Durrani dynasties in the 18th century, with Ahmad Shah Abdali being considered as the founder of the state. In the late 19th century, Afghanistan became a buffer state in the "Great Game" between British India and the Russian Empire. Its border with British India, the Durand Line, was formed in 1893 but it is not recognized by the Afghan government and it has led to strained relations with Pakistan since the latter's independence in 1947. Following the Third Anglo-Afghan War in 1919 the country was free of foreign influence, eventually becoming a monarchy under Amanullah Khan, until almost 50 years later when Zahir Shah was overthrown and a republic was established. In 1978, after a second coup Afghanistan first became a socialist state and then a Soviet protectorate. This evoked the Soviet–Afghan War in the 1980s against mujahideen rebels. By 1996 most of Afghanistan was captured by the Islamic fundamentalist group the Taliban, who ruled as a totalitarian regime for over five years. Following the 9/11 attacks, an intervention by the US and its allies forcibly removed the Taliban from power, and a new democratically-elected government was formed, but the Taliban still control a significant portion of the country. Afghanistan is a unitary presidential Islamic republic. The country has high levels of terrorism, poverty, child malnutrition, and corruption. It is a member of the United Nations, the Organisation of Islamic Cooperation, the Group of 77, the Economic Cooperation Organization, and the Non-Aligned Movement. Afghanistan's economy is the world's 96th largest, with a gross domestic product (GDP) of $72.9 billion by purchasing power parity; the country fares much worse in terms of per-capita GDP (PPP), ranking 169th out of 186 countries as of 2018.

Volunteering is generally considered an altruistic activity where an individual or group provides services for no financial or social gain "to benefit another person, group or organization". Volunteering is also renowned for skill development and is often intended to promote goodness or to improve human quality of life. Volunteering may have positive benefits for the volunteer as well as for the person or community served. It is also intended to make contacts for possible employment. Many volunteers are specifically trained in the areas they work, such as medicine, education, or emergency rescue. Others serve on an as-needed basis, such as in response to a natural disaster. In a military context a volunteer is someone who joins an armed force of their own volition rather than being conscripted, and is usually paid.
