Senegal's first president, Léopold Senghor, advocated close relations with France and negotiation and compromise as the best means of resolving international differences after Senegal's independence from its status as a French colony. To a large extent, the two succeeding presidents, Abdou Diouf and Abdoulaye Wade, have carried on Senghor's policies and philosophies. Senegal has long supported functional integration among French-speaking West African states through the West African Economic and Monetary Union.

Senegal has a high profile in many international organizations and was a member of the UN Security Council in 1988–89. It was elected to the UN Commission on Human Rights in 1997. Friendly to the West, especially to France and to the United States, Senegal also is a vigorous proponent of more assistance from developed countries to the Third World. Additionally, Senegal has been a member state of the African Union since 1963.

Senegal borders The Gambia, Mauritania, Mali, Guinea, and Guinea-Bissau. Senegal enjoys mostly cordial relations with its neighbors. In spite of clear progress on other fronts with Mauritania (border security, resource management, economic integration, etc.), there remains the problem of an estimated 30,000 Black Mauritanian refugees living in Senegal.

Senegal is also a member of the International Criminal Court with a Bilateral Immunity Agreement of protection for the US-military (as covered under Article 98).

Pre-colonial foreign policy Senegal was regarded as Senegambia before the arrival of Europeans (Jaiteh), where a number of independent kingdoms settled. By the 15th century, when the first Europeans arrived, Senegambia was linked to intra and inter-regional (Decourse, 8) trade networks that extended throughout the coast. During the 17th and 18th centuries, the African slave trade took advantage of autonomous kingdoms such as, the Wolof and Jolof kingdoms (Tang, 3). The establishment of French colonies coupled with the competing hegemonic power between local ethnic groups within the Wolof kingdom led to a power void after traditional rulers could not prevent the French from impeding the establishments already in place by politicians and elites (Venema, 4) . The change from slave trade to the trade of cash crops set the precedent for the collapse of states within both empires (Gray, 3). The French used Senegal's advantageous geographic location, on the coast of the Atlantic Ocean, to safeguard their interest in the trade of groundnuts (Schraeder and Gaye, 488). The foreign policy of Senegal is also characterized by the religious values and beliefs of Islam. The spiritual traditions and foundations of Senegal represent another facet of foreign policy in and outside of the region. Political and diplomatic actors are ultimately determined by marabouts that intercede on behalf of the people to Allah (Schraeder and Gaye, 489). Some marabouts establish loyalist relationships of patron with political leaders. Marabouts do not make policy, but their support is essential to the stability of government (Behrman Creevey, 262).

Independence (1960–1989) Senegalese independence began in 1960 with Léopold Sedar Sénghor as the first president and was succeeded by Abdou Diouf in 1980. Senegalese diplomats in the Ministry of Foreign Affairs believe that West Africa must unite in order to not only remain competitive in an international economy dominated by superpowers like China and the United States, but also promote and consolidate economic development within West Africa. Senegalese policy officials prioritize and use the individual strengths of surrounding African countries in order to strengthen regional economies and weaken regional dependency on foreign actors. This combative approach for western influence is underscored in the Senegalese constitution in clause four of the preamble: "must spare no effort in the fulfillment of African Unity". These efforts have been actively pursued through formal diplomatic agreements with neighboring countries, such as the Mali Foundation in 1960, the Federation with Gambia from 1982 to 1989, as well as informal forms of cooperation such as the Inter-State Authority in the Fight Against Drought in the Sahel (CILSS), The Economic Community of West African States (ECOWAS), The Joint African and Malagasy Organization (OCAM), the Organization for the Development of the Gambia River Valley (OMVG), and the Organization for the Development of the Senegal River Valley (OMVS).

Cold War Foreign Policy During the Cold War, Senegal was part of the non-aligned world and remained neutral throughout the conflict. In 1965, the first Foreign Minister of Senegal, Doudou Thiam, published a book titled "The Foreign Policy of African States." Thiam implored Africa to move beyond the ideological divisions of the Cold War to form a third neutral ideology on which African states could build their own path. This concept of non-alignment became a central theme in Senegalese politics. Senegal's first President Léopold Sedar Sénghor privileged the country's relationship with France and sided with French President Charles de Gaulle against "superpower" domination between the U.S. and the Soviet Union. France accounted for 95% of all investments in Senegal and 80% of Senegal's foreign trade in the 1960s. Due to the close economic relationship between France and Senegal, Senegal appealed to French protectionism over West Africa, declining to move too closely to any superpower. Nonetheless, Senegal's ties with Western countries like France tilted its alignment westward.

"La Francophonie" One of the important strategic goals of Senegalese leaders was the integration and cooperation of Francophone Africa; a policy known as "la Francophonie" coined by President Senghor. The promotion of this concept played a key role in the formation of worldwide summits, such as the Franco-African Summit, that allowed Senegal to emerge as a leader within the francophone movement in Africa, African consolidation, unification and cooperation are at the center of Senegalese foreign policy. Senegal was also one of the founding members of several organizations designed to integrate Francophone Africa, including the African and Malagasy Common Organization in 1961 and the Malian Federation in 1960.

"Négritude" Another cornerstone of Senegalese foreign policy during the Cold War was the exemplification of African Art and international cultural ties. This was connected to President Senghor's ideology of "Negritude" which emphasized Pan-Africanism and the exceptionalism of African culture. In 1966, the First World Festival of Negro Arts was hosted in Dakar, Senegal. The event was a tribute the art and excellence of the African Diaspora across the world. In the development of the event, Senegal strengthened relations with the UN, African states like Ethiopia, and nations on both sides of the Cold War. The United States was one of the key supporters of the event, sending the largest delegation of performers, artists, and technician of any of the 43 participating nations. Despite an official policy of non-alignment, Senegal used African Art and Culture as a negotiation tool with international partners and build a "soft" foreign policy with a variety of nations. At the same time, the First World Festival of Negro Arts was seen by many post-colonial states as neocolonial due to its connection to French concept of Negritude and cooperation with Western powers. The event strained relationships with Algeria and Guinea who would host their own festival in the years following in Algiers.

Iran-Senegal Relations Senegal's non-alignment policy also contributed to the building of significant relationships with other nations. President Sénghor developed strong political and economic ties with the Shah of Iran, Mohammad Reza Pahlavi. In 1971, formal diplomatic relations were established, and, by 1973, the Shah was providing $2.4 million in developmental loans for Senegal (Steele 180–1). Iran continued to provide development investment and loans from 1974 to 1979 that focused on the trade of Iranian oil for Senegalese phosphate, including the creation of an oil refinery and a new adjacent city in Senegal (Steele 183–4). The project was never completed due to funding gaps and the Iranian Revolution, despite strong intentions to move forward.

Current Partnerships

U.S.-Senegal Relations Diplomatic relations between the United States and Senegal began in 1960, following independence and the dissolution of the Mali Federation. Early after independence, a relationship was formed between President Senghor and U.S. President John F. Kennedy as part of the latter's "African Policy." As part of Senegal's policy of non-alignment and African Socialism, bilateral relations between the two were limited but meaningful. The United States contributed aid to Senegal, including for the First World Festival of Negro Arts, and maintained consistent contact with the country throughout the Cold War via its US Agency for International Development (USAID).

Today, U.S.-Senegal Relations are defined by foreign aid, military cooperation, and the protection of democracy in the region. The United States provides a growing amount of economic aid to the country. Senegal has received aid for democracy promotion, food security, and development projects like $1.5 million in aid for solar energy and nano-loan financing systems. Health diplomacy is another sector of aid that the United States and Senegal collaborate on. These include programs for child health, the prevention of Malaria, and family planning funded by USAID. Recently, the US sent $10.7 million of emergency aid and 99,450 vaccine does to Senegal to combat the COVID-19 pandemic. Defense has also been a major area of partnership as Senegal has remained a stable nation in a region consistently fraught with violence. In 2016, both nations also signed a Defense Cooperation Agreement that would ensure joint-military training and missions in West African states affected by Islamic extremism and alleviate the need for more troops to be stationed in Senegal. Senegal has also supported U.S. military missions in Iraq (1991), Niger (2016), and even its own territory during the Ebola outbreak of 2014, through the auspices of the United States African Command (AFRICOM). Another major priority of the United States in Senegal is the promotion and protection of democracy. Senegal's democratic system has persisted for decades and has become more democratic following the Cold War, garnering the attention of the U.S. as a model state for West Africa. The United States manages several programs or aid packets meant to increase democratic diplomacy. One of these programs is conducted by the United States Information Agency which help hold workshops and training with Senegalese news federation and reporters to increase the independence and power of the press in the country.

The relationship between the United States and Senegal is often limited by the country's strong ties with France, preventing deep connections from forming without diplomatic conflict. The French have been critical of recent "hard" diplomacy actions by the U.S., including AFRICOM and limited the nation's African Crisis Response Initiative (ACRI) to the training of African forces in West Africa.

Intergovernmental Organizations

ECOWAS Senegal is a Zone A member of ECOWAS since its formation in 1975 with the signing of the Treaty of Lagos and the largest contributor of troops in the Economic Community of West African States Monitoring Group (ECOMOG).
