Relationship Between Tanzania and the USA

I. At a Glance – US‑Tanzania Relations

II. Historical Overview – From Zanzibar Trade to Cold War Tensions

The relationship between what is now Tanzania and the United States predates the independence of both Tanganyika and Zanzibar. In the early 19th century, American merchant vessels sailed thousands of miles to engage with the East African coast. By 1837, the United States had established one of its first diplomatic missions in Africa in Zanzibar, then a powerful Omani Arab sultanate that dominated the Indian Ocean trade[reference:0]. Zanzibar exported cloves, copal, and other high‑value commodities that were in strong demand across global markets, and this early engagement reflected a principle of identifying and investing in emerging economic corridors.

The Cold War era, however, introduced significant tension. President Julius Nyerere, a committed socialist and Pan‑Africanist, was deeply critical of US foreign policy, particularly its support for colonial powers and its perceived indifference to liberation movements in southern Africa. In January 1965, in one of his boldest foreign policy decisions, Nyerere ordered the expulsion of two American diplomats – Robert Gordon, a counsellor at the US Embassy in Dar es Salaam, and Frank Carlucci, the US Consul in Zanzibar – over allegations of subversion and attempts to destabilise his government[reference:1]. This act set a pattern of friction that lasted through the 1980s, as Nyerere’s socialist economic policies and his support for anti‑apartheid movements often placed him at odds with Washington’s priorities[reference:2].

The end of the Cold War and Nyerere’s voluntary retirement in 1985 opened the door to a more pragmatic and cooperative relationship. By the late 1990s, the two countries had found common ground on debt relief, refugee crises, and economic liberalisation, culminating in President Benjamin Mkapa’s 1999 visit to Washington with a delegation of business executives – a clear sign of the increasing level of cooperation on trade and investment issues[reference:3].

III. The 1998 Embassy Bombing – A Turning Point

On 7 August 1998, terrorists associated with Al‑Qaeda bombed the US Embassies in Dar es Salaam and Nairobi, Kenya. The attacks killed 224 people – including 12 Americans – and injured over 4,500. The Dar es Salaam attack horrified both Tanzanians and Americans alike and drew condemnation from around the world. In the aftermath, Tanzania began to receive substantial financial aid from the US for anti‑terrorist efforts and police training[reference:4]. The embassy bombing marked a turning point: it transformed the relationship from one of occasional cooperation to a strategic partnership focused on shared security concerns, a trajectory that continues to this day.

IV. Economic Relations – Trade, AGOA, and Strategic Minerals

Economic ties form a critical pillar of the US‑Tanzania relationship. The African Growth and Opportunity Act (AGOA), enacted in 2000, was the centrepiece of US trade policy with sub‑Saharan Africa, offering duty‑free access to the US market for over 1,800 products from eligible African countries[reference:5]. Tanzania was a major beneficiary, particularly in garments, agricultural goods, and minerals. In 2023, US imports under AGOA were valued at nearly $10 billion globally, though Tanzania’s exports to the US under the programme stood at approximately $210 million – only 1.86% of the country’s overall exports[reference:6].

However, AGOA expired on 30 September 2025, and as of mid‑2026, it has not been renewed[reference:7]. The Tanzanian government has expressed concern about the potential impact, noting that local industries that found markets in the US could face significant setbacks[reference:8]. The country is now relying on regional blocs such as the East African Community to urge the US Congress to extend the deal or negotiate alternative trade arrangements[reference:9]. Independent economists have warned that without AGOA, Tanzanian goods – especially textiles – would face higher tariffs and become less competitive against products from Asia and other regions[reference:10].

Despite the uncertainty over AGOA, the US remains an important source of foreign direct investment in Tanzania. In March 2026, Tanzania signed a package of agreements with Panda Hill Tanzania Limited, a US‑owned company, to develop a niobium mine in Mbeya Region[reference:11]. Niobium is a strategic metal used to strengthen steel and produce high‑performance alloys for electric vehicles and aerospace components. The deal positions Tanzania as the world’s fourth‑largest producer of niobium, with planned production of roughly 100,000 tonnes per year, and establishes the country as a reliable trade partner in advanced materials rather than a raw commodity exporter[reference:12].

More broadly, Tanzania is positioning itself as a key link in US supply chain security. The country holds one of the world’s largest graphite resources (fifth globally), the second‑largest known helium reserves, and the largest rare earth element deposits in Africa – all of which are critical inputs for clean energy technologies, advanced electronics, and defence applications[reference:13]. As the United States prioritises supply chain security and strategic resource partnerships, Tanzania is emerging as a “highly consequential – yet under‑leveraged – player” in this new economic order[reference:14].

V. Development Assistance – USAID, PEPFAR, and the Future of Aid

The United States is Tanzania’s largest bilateral donor. Through the US Agency for International Development (USAID), the President’s Emergency Plan for AIDS Relief (PEPFAR), and other programmes, Washington has provided billions of dollars in assistance over the past six decades, supporting health, education, governance, economic growth, and conservation[reference:15].

Key USAID initiatives include the Feed the Future Tanzania Kilimo Tija project, a $37.9 million programme aimed at transforming the horticulture sector into a regional powerhouse. In its first year, the project supported 2,500 micro, small and medium enterprises, generating 7,400 new jobs and over $100,000 in produce sales[reference:16]. Other programmes include the Tuhifadhi Maliasili Project, which has played a key role in restoring Tanzania’s 61 wildlife corridors[reference:17].

However, the aid landscape is shifting. In early 2025, USAID operations in Tanzania were closed under a new US policy framework. The US Embassy has assured that development projects will soon resume under a new framework, with the government working to revive many initiatives through alternative channels[reference:18]. In the health sector, Tanzania has already begun to adjust: following the withdrawal of USAID support, the government allocated US$9 million in the 2025/2026 financial year to sustain family planning interventions nationwide[reference:19]. The government also set an ambitious target to finance 60% of neglected tropical disease interventions with domestic resources by 2026, demonstrating a move toward self‑reliance[reference:20].

VI. Military and Security Cooperation – AFRICOM and Maritime Security

The United States and Tanzania share a robust security partnership, particularly in the maritime domain. Tanzania is a key partner for US Africa Command (AFRICOM) in addressing regional threats, including piracy, terrorism, and illicit trafficking in the Indian Ocean[reference:21].

Joint military exercises are a regular feature of the relationship. In February 2025, Cutlass Express – a two‑week joint maritime training exercise – brought together 15 countries, including the US and Tanzania, to practice modern boarding techniques, legal searches, and the integration of maritime awareness systems[reference:22]. In February 2026, the US hand‑overed a new maritime facility to the Tanzania People’s Defence Force (TPDF) Navy, coinciding with Cutlass Express 2026. The facility is designed to enhance Tanzania’s capacity to secure its own maritime domain, supporting counter‑illicit trafficking and maritime law enforcement along the northern coastline[reference:23].

In July 2025, AFRICOM commander General Stephen Townsend conducted a two‑day visit to Tanzania, meeting with senior defence officials and opening the first joint special forces training exercise between the two nations since 2017[reference:24]. The annual African Land Forces Summit and Eastern Accord 16 exercise were also hosted in Tanzania, underscoring the country’s strategic importance to US military planning on the continent.

Tanzania is also included in the Pentagon’s State Partnership Program, which pairs state National Guards with partner nations to build capacity and foster military‑to‑military relationships. These engagements have included canine detection training, logistics support, and gender mainstreaming seminars[reference:25].

VII. Cultural and Educational Exchanges – People‑to‑People Ties

Beyond government‑to‑government cooperation, the US‑Tanzania relationship is sustained by deep people‑to‑people connections. The Fulbright Program, Hubert Humphrey Fellowship, and the Young African Leaders Initiative (YALI) have brought thousands of Tanzanians to the United States for academic and professional exchanges[reference:26]. The Peace Corps, which was discontinued in Tanzania in the 1960s due to objections to US involvement in the Vietnam War, was re‑established in 1979 and continues to provide assistance in education and health through the provision of teachers[reference:27].

The US Embassy also supports cultural preservation through the Ambassador’s Fund for Cultural Preservation, which has funded restoration projects at Kilwa Kisiwani, two mosques in Zanzibar, and an Anglican Church in Stone Town[reference:28]. An estimated 30,000–40,000 Tanzanian‑Americans live in the United States, and their remittances and advocacy further strengthen the bilateral relationship.

VIII. Recent Tensions – The 2025 Election and Proposed Sanctions

The October 2025 general election in Tanzania marked a significant downturn in US‑Tanzania relations. President Samia Suluhu Hassan was re‑elected with 97.66% of the vote, but the election was marred by the disqualification of major opposition candidates, widespread allegations of irregularities, and post‑election violence that, according to an independent government inquiry, claimed 518 lives[reference:29]. The United States expressed serious concern over the conduct of the polls and the subsequent crackdown.

In May 2026, the US sanctioned Senior Assistant Commissioner of Police Faustine Jackson Mafwele, banning him from entering the United States, over his alleged role in the torture of two activists – Boniface Mwangi of Kenya and Agather Atuhaire of Uganda – who had travelled to Tanzania to observe the trial of opposition leader Tundu Lissu[reference:30]. The US State Department stated there was “credible information” that Mafwele was involved in “gross violations of human rights”[reference:31].

Days later, US Senators Jeanne Shaheen and Ted Cruz introduced the Reassessing the United States–Tanzania Bilateral Relationship Act, a bipartisan bill calling for a comprehensive review of relations and proposing sanctions, including visa restrictions on certain individuals, a reassessment of security cooperation, and a review of economic engagement[reference:32]. The bill also requires Washington to assess “the extent of the People’s Republic of China’s military, economic and political engagement in Tanzania”[reference:33].

In response, the Tanzanian government defended its sovereignty, invited the bill’s sponsors to visit the country, and engaged in diplomatic outreach through its embassy in Washington[reference:34]. The National Assembly debated the proposed sanctions, with some MPs calling for a firm response and others urging calm engagement[reference:35]. Political analysts noted that the parliamentary debate reflected a broader tension between sovereignty and international accountability, while also expressing concern that prolonged tensions could affect cooperation in trade, investment and security[reference:36].

As of June 2026, the bill has not passed the full Senate, but the diplomatic pressure has clearly escalated. President Samia has taken some steps to address the concerns, including appointing a new independent commission of inquiry to investigate criminal culpability linked to the post‑election violence[reference:37]. However, the international community, including the United States, continues to watch closely, and the future of the bilateral relationship hangs in the balance.

IX. Final Verdict – A Partnership at a Crossroads

The relationship between Tanzania and the United States is one of the most consequential bilateral partnerships in East Africa. Over nearly two centuries, the two nations have evolved from early trading partners to Cold War adversaries, from reluctant allies to strategic partners in health, security, and development. The US remains Tanzania’s largest bilateral donor, a major trading partner, and a key security ally. However, the partnership is at a crossroads. The expiration of AGOA, the closure of USAID operations, and the serious diplomatic strains following the October 2025 election have raised fundamental questions about the future of the relationship.

For Tanzania, the challenge is to balance its desire for sovereign autonomy with its need for international cooperation and investment. For the United States, the challenge is to reconcile its commitment to democratic principles with its strategic interest in a stable, prosperous, and resource‑rich Tanzania. The coming years will determine whether this historic partnership can weather the current storm and emerge stronger, or whether it will be fundamentally reshaped. For travellers and investors alike, understanding the nuances of this relationship is essential to navigating the economic and political landscape of modern Tanzania.
