In 1999 Namibia signed a mutual defence pact with its northern neighbour Angola. This affected the Angolan Civil War that has been ongoing since Angola's independence in 1975. Namibia's ruling party SWAPO wanted to support the ruling party MPLA in Angola to fight the rebel movement UNITA, whose stronghold is in southern Angola, bordering Namibia. The defence pact allowed Angolan troops to use Namibian territory when attacking UNITA.

The alliance between SWAPO and MPLA has deep roots and began as both Angola's and Namibia's ruling parties sought independence during the mid twentieth century and into the Angolan Civil War. In Angola, the leftist movement MPLA was fighting the rightist movement UNITA, which was supported by South Africa. In Namibia, SWAPO, then being a rebel movement, was fighting for independence from South Africa along the Angolan border. Angola allowed SWAPO to establish training and refugee camps for Namibians and PLAN (People's Liberation Army of Namibia) fighters. As MPLA and SWAPO shared a common ideological ground, and had a common enemy in South Africa, they came to cooperate.

The Angolan civil war resulted in a large number of Angolan refugees coming to Namibia. At its peak in 2001 there were over 30,000 Angolan refugees in Namibia. The calmer situation in Angola has made it possible for many of them to return to their home with the help of UNHCR, and in 2004 only 12,600 remained in Namibia. ^[88] Most of them reside in the refugee camp Osire north of Windhoek.

Upon independence in 1990, Namibia's economy was still tied to South Africa's.^[98] To this day, the economy of Namibia is still closely contacted to South Africa through both institutional relationships (Southern African Customs Union, for example) and privately owned mining concessions.^[99] The South African rand is still legal currency within Namibia, while the Namibian dollar is not so in South Africa and the currencies are traded on par locally.

In 1990 official relations started; Canada has dispatched an Honorary Consul to Windhoek.^[103]

Canada is one of the main destinations for Namibian refugees. Together with Botswana and Denmark, Canada has been granting asylum to people fleeing Namibia in the aftermath of the Caprivi conflict, and particularly the Caprivi treason trial that followed in which the Namibian government was accused of human rights violations.^[104] Only in 2010 Canada has changed its standpoint and is now considering the CLA to be a terrorist organisation that has "attempted to usurp an elected government". Nonetheless, Canada received a steady inflow of Namibian immigrants who seek economic betterment under the pretense of humiliation and harassment in Namibia. In 2011 more than 1,000 Namibians entered Canada. Three-quarters of them applied for refugee status, but only a few were successful.^[105]

Namibia has been included in President Bush's International Mother and Child HIV Initiative and the Emergency Plan for AIDS Relief.

First contacts between people of the two countries took place when German missionaries were hired by the London Missionary Society to commence working in Southern Namibia during the late 18th and early 19th century.^[121] In the 1880s the German Empire came to what is now Namibia as a colonizing power, creating German South-West Africa. The German colonial rule was marked by tensions and led to the genocide of the Herero and Namaqua people from 1904 to 1907, which resulted in the deaths of 65,000 Herero (80 percent of the total Herero population), and 10,000 Nama (50% of the total Nama population). The colony was ruled by Germany until 1915 when it was conquered by troops from the Union of South Africa.

During South African rule, German was one of the three official languages of Namibia, the others being Afrikaans and English. Likewise during Apartheid rule, West Germany maintained a consulate in Windhoek despite United Nations resolutions calling for the isolation of South Africa.

Namibian independence in 1990 coincided with German reunification, resulting in an initially slow development of diplomatic relations. However, in both 1989 and 2004 the German government acknowledged its responsibility for Namibia as a priority partner country.^[122] Since then German Development minister Heidemarie Wieczorek-Zeul visited Namibia, asking the country for forgiveness of the past.^[123] Today, not least due to substantially improved co-operation and exchange, as well as by fate of the permanent presence of the "German tribe in Namibia", the two countries have mostly learnt to a new dialogue, which at times also still stagnates.

Relations between Namibia and Russia were considered "excellent" in 2006 by then-Namibian Minister of Education Nangolo Mbumba, while Russia expressed a desire for even stronger relations, particularly in the economic field. Also in 2006, the Namibia-Russia Intergovernmental Commission on Trade and Economic Cooperation was officially opened during a visit by Russian Natural Resources Minister Yuri Trutnev to Windhoek. During said visit, the Minister said Russia was interested in investing in oil, hydro-electric power and tourism.^[125] In 2007, Russian Prime Minister Mikhail Fradkov held discussions with Namibian Deputy Prime Minister Nahas Angula and President Hifikepunye Pohamba in regards to the possibility of developing Namibia's significant uranium deposits with an aim towards creating a nuclear power plant in the country.^[126] In 2008, Trutnev returned to Namibia, this time to Swakopmund, to meet at the third annual Intergovernmental Commission. Top foreign ministry official Marco Hausiku and his deputy Lempy Lucas represented Namibia in discussions with Trutnev.^[127]
