As global economic dynamics undergo a fundamental reordering in the 21st century, Africa has emerged as a critical battleground for influence between major world powers ( Ghosh, 2018 ). No longer defined solely by Cold War-era military alliances or ideological alignments, today’s contest is waged through infrastructure, particularly ports, railways, and roads, that underpin the continent’s economic transformation ( Barlow & Clarke, 2019 ). This competition is increasingly characterized not by overt confrontation, but by what scholars describe as “infrastructure diplomacy” ( Moyo, 2018 ), where state-backed enterprises and development finance institutions become instruments of geopolitical strategy. In this context, Africa is not merely a passive recipient of external investment but a dynamic arena where strategic interests, developmental aspirations, and global rivalries intersect.

Among the most visible flashpoints of this emerging infrastructure-centered rivalry are maritime assets, specifically ports that serve as gateways for trade, security coordination, and regional integration ( Fuchs & Klann, 2019 ). Angola’s Lobito Port, situated on the Atlantic coast, and Tanzania’s Dar es Salaam Port, positioned along the Indian Ocean, exemplify this phenomenon ( Lee, 2020 ). These ports do not serve isolated national purposes; they function as multi-country logistical lifelines, providing critical access to the global economy for landlocked neighbors such as Zambia, Malawi, and the Democratic Republic of Congo (DRC) ( Niu, 2020 ). In doing so, they have become central nodes in transnational trade corridors, resource export strategies, and continental integration efforts such as the African Continental Free Trade Area (ACFTA).

Their strategic importance has attracted the focused attention of both China and the United States, two nations whose visions for Africa diverge sharply ( Wang, 2021 ). China’s engagement is defined by high-capital, high-visibility projects often embedded within its Belt and Road Initiative (BRI) a global infrastructure strategy designed to enhance trade connectivity and deepen economic interdependence with partner nations ( Liu, 2021 ). Chinese investments in African ports are typically comprehensive, encompassing not just terminal upgrades but also rail links, special economic zones, and customs facilities. These are financed through state-backed loans, concessional credit, and public-private partnerships involving Chinese state-owned enterprises.

In contrast, the United States has pursued a more conservative approach centered on technical assistance, institutional strengthening, and trade liberalization initiatives ( Osei, 2022 ). Through programs such as the African Growth and Opportunity Act (AGOA), the U.S. promotes export access for African goods ( Musila, 2019 ), while agencies like USAID and the Millennium Challenge Corporation (MCC) support reforms in governance, transparency, and customs efficiency ( Hoh, 2021 ). Although these initiatives provide valuable support for long-term institutional resilience, they often lack the scale, immediacy, and visibility associated with Chinese capital projects.

This divergence in strategy reflects deeper philosophical differences in how each power views its role in Africa’s development ( Shen, 2020 ). For China, infrastructure is a lever of influence and a tool for resource extraction, market expansion, and soft power projection ( Brautigam, 2021 ). For the U.S., the emphasis is placed on enabling environments, strengthening governance frameworks, and promoting private-sector-led growth ( Dollar, 2020 ). The result is a stark asymmetry in presence and perception, with Chinese-built infrastructure physically transforming African landscapes at a pace that U.S. initiatives have struggled to match ( Ghosh, 2018 ).

The Lobito and Dar es Salaam ports are microcosms of this broader geopolitical contest ( Xu, 2021 ). Their transformation offers a unique lens to examine how great powers seek to shape Africa’s economic geography and political future not with bullets and bases, but with cranes, shipping lanes, and strategic corridors ( Zhang, 2019 ). This paper investigates how the competition over these ports reveals the evolving nature of global power projection and what it means for the political economy of African states navigating between opportunity and dependency.

This study employs a mixed-methods approach, integrating quantitative and qualitative analyses to evaluate Chinese and U.S. involvement in the Lobito and Dar es Salaam ports ( Kuo, 2019 ). Quantitative data, such as trade volumes, container throughput (TEUs), and port traffic from 2010 to 2023, were sourced from institutions including the World Bank, IMO, and national trade ministries ( World Bank, 2022 ). Investment figures were compiled from government reports, SOE disclosures, and independent assessments by think tanks like Brookings and CSIS ( Niu, 2020 ). Complementing this, qualitative insights were drawn from academic publications, policy documents, and multilateral agency reports to contextualize strategies like China’s BRI and the U.S.’s PGII ( Hoh, 2021 ).

The analytical framework centers on three pillars: economic performance assessment through time-series and growth trend analysis ( Barlow & Clarke, 2019 ); classification of infrastructure investments by purpose, origin, and operational model ( Niu, 2020 ); and geopolitical mapping of influence strategies and policy discourse. Triangulating these elements allows for a comprehensive understanding of how infrastructure projects function as tools of economic statecraft in Africa ( Moyo, 2018 ).

Located on Angola’s Atlantic coast, Lobito Port is more than a logistical hub; it is a keystone in China’s West African strategy ( Cheng, 2020 ). Historically tied to Angola’s oil exports, Lobito has now been repositioned by Chinese capital as a multi-use export node for Southern Africa’s minerals ( Lee, 2020 ).

Dar es Salaam, Tanzania’s primary port, is the busiest maritime facility in East Africa and serves as the gateway for multiple landlocked economies ( Dollar, 2020 ). Unlike Lobito, Dar es Salaam operates in a multipolar regional trade context, where infrastructure is closely linked to cross-border economic integration ( Brautigam, 2021 ).

China’s infrastructural reach is both broader and deeper, creating logistical chokepoints that align with its broader geopolitical calculus ( Liu, 2021 ). The U.S., while maintaining a strategic interest, has not matched the scale or continuity of Chinese initiatives ( Osei, 2022 ).

The cases of Lobito and Dar es Salaam demonstrate that ports have evolved from simple commercial hubs into critical tools of economic statecraft, playing a pivotal role in the broader geopolitical and strategic competition between global powers ( Brautigam, 2021 ). At the heart of this transformation is China’s Belt and Road Initiative (BRI), which has redefined the role of infrastructure development in international relations ( Shen, 2020 ).

Through its capital-intensive and vertically integrated approach, China not only funds the construction of state-of-the-art port facilities but also maintains operational control over them through state-owned enterprises (SOEs) like the China Communications Construction Company (CCCC) ( Osei, 2022 ). This strategy allows China to shape regional supply chains, secure long-term access to vital resources, and trade rules and logistics networks ( Niu, 2020 ). By embedding Chinese norms, firms, and infrastructure into Africa’s developmental framework, China solidifies its role as a key player in shaping the continent’s economic future ( Lee, 2020 ).

In contrast, the U.S. approach emphasizes governance and institutional support, prioritizing the establishment of regulatory frameworks, trade facilitation, and capacity-building programs ( Osei, 2022 ). Through initiatives such as the African Growth and Opportunity Act (AGOA), U.S. efforts focus on creating conditions for sustained economic growth by improving the legal and institutional environments ( Dollar, 2020 ). While this focus on “soft power” is vital for long-term stability and resilience ( Moyo, 2018 ), it lacks the immediate, visible impact of large-scale infrastructure projects ( Ghosh, 2018 ). African governments, often facing urgent developmental needs, may find the U.S. model appealing in principle but less effective in providing the rapid physical transformation and economic lift required to meet their goals ( Lee, 2020 ). As a result, the U.S. approach, despite its potential for fostering sustainable governance, can be perceived as insufficient in regions where quick, tangible development outcomes are highly valued ( Hoh, 2021 ).

This strategic divergence between China and the U.S. creates a complex decision-making environment for African states ( Shen, 2020 ). On the one hand, Chinese investments offer the promise of rapid development and tangible infrastructure improvements, with vast amounts of capital flowing into ports, railways, and roads ( Niu, 2020 ). This is particularly attractive in countries where the need for urgent infrastructure expansion and modernization is a top priority ( Kuo, 2019 ). However, this speed and scale come with significant trade-offs. Chinese investments are often accompanied by substantial debt, and the long-term fiscal autonomy of recipient nations may be compromised ( Brautigam, 2021 ). Furthermore, the heavy reliance on Chinese firms for the operation and maintenance of infrastructure can create a sense of strategic dependency, potentially limiting a country’s ability to make independent economic decisions in the future ( Zhang, 2019 ).

On the other hand, U.S. engagement, with its emphasis on governance and institutional development, seeks to create a more sustainable foundation for economic growth ( Musila, 2019 ). By fostering democratic principles, enhancing regulatory frameworks, and supporting transparency, the U.S. approach builds institutional resilience that can help African nations withstand economic shocks and maintain long-term stability ( Fuchs & Klann, 2019 ). However, the lack of substantial “hard” infrastructure investments may make U.S. efforts appear less attractive to governments that are under pressure to deliver immediate results in the form of new ports, roads, and railways ( Ghosh, 2018 ). For many African leaders, the need for visible, physical transformation often outweighs the intangible benefits of improved governance and institutional capacity ( Lee, 2020 ). Thus, while the U.S. model may provide a foundation for long-term development, it faces challenges in competing with China’s more immediately impactful infrastructure-driven approach, which offers both economic and geopolitical advantages ( Osei, 2022 ).

The analysis of Lobito and Dar es Salaam reveals how port infrastructure has become a central arena for the U.S.-China economic rivalry in Africa ( Liu, 2021 ). China’s substantial investments have yielded tangible results in trade volume, infrastructure modernization, and strategic positioning ( Hoh, 2021 ). The U.S., although a legacy partner in governance and trade facilitation, trails behind in visibility and impact ( Niu, 2020 ).

Ultimately, ports such as Lobito and Dar es Salaam are no longer neutral assets; they are geostrategic levers reshaping regional trade, security alignments, and global influence ( Shen, 2020 ). For African states, the challenge is not choosing sides but leveraging this competition to ensure diversified investment, regulatory sovereignty, and sustainable development ( Zhang, 2019 ).
