Foreign policy

Upon her election to office, Sirleaf made her first foreign trip as President to neighboring Ivory Coast, meeting with Ivorian President Laurent Gbagbo in an attempt to repair relations between the two countries following Côte d'Ivoire's support of the Movement for Democracy in Liberia during the Second Liberian Civil War. During the 2010–2011 Ivorian crisis, Sirleaf, as chairperson of the Mano River Union, supported ECOWAS's recognition of Gbagbo's opponent, Alassane Ouattara, as the winner of the disputed presidential election, but rejected calls for a military solution to the crisis.

Sirleaf also forged close relations with the United States, Liberia's traditional ally. Following the establishment of United States Africa Command (AFRICOM) by the United States military, Sirleaf offered to allow the US to headquarter the new command in Liberia, the only African leader to do so. The command was eventually headquartered in Stuttgart, Germany. On 15 March 2006, President Sirleaf addressed a joint meeting of the United States Congress, asking for American support to help her country "become a brilliant beacon, an example to Africa and the world of what love of liberty can achieve."

Sirleaf has also strengthened relations with the People's Republic of China, reaffirming Liberia's commitment to the One-China policy. In return, China has contributed to Liberia's reconstruction, building several transmitters to extend the Liberia Broadcasting System nationwide and constructing a new campus for the University of Liberia.

Sirleaf is a member of the Council of Women World Leaders, an international network of current and former women presidents and prime ministers whose mission is to mobilize the highest-level women leaders globally for collective action on issues of critical importance to women and equitable development.

During the 2011 Libyan civil war, Sirleaf added her voice to the international community who asked the previous Libyan leader Muammar al-Gaddafi to cease the use of violence and tactics of political repression. However, she criticized the international military intervention in Libya, declaring that "violence does not help the process whichever way it comes". Her government later severed diplomatic ties with Libya, stating that "The Government took the decision after a careful review of the situation in Libya and determined that the Government of Colonel Gaddafi has lost the legitimacy to govern Libya."

On 27 February 2015, President Sirleaf was expected to make a visit to U.S. President Barack Obama at the White House in Washington, D.C., according to an official online statement from the Office of the White House Press Secretary. Among other issues, they planned to discuss the hope to expeditiously close the recent 2013–2015 Ebola virus epidemic, which heavily affected Liberia, Sierra Leone, and Guinea, and other areas in West Africa (and beyond in other countries due to importation of cases for treatment and some new infections), down to an ideal of zero reported cases in Liberia and nearby areas in the near future, with continuing monitoring and reporting, care, support, and fiscal and professional assistance. They also planned to discuss how to sustain and rebuild the healthcare infrastructure and the country's other difficulties in the wake of the massive outbreak's morbidity and mortality toll and impact on the area, as well as review progress that had been made and efforts to continue it.
