Donald Yamamoto

From April 22–23, 2006, Yamamoto met with current Chadian President Idriss Déby to discuss Chad's dispute with the World Bank over allocation of its petroleum funds and the possibility of a U.S.-led, United Nations-monitored peace keeping force to end the Chadian-Sudanese conflict.

The Government of Chad repeatedly accused the Government of Sudan of complicity in United Front for Democratic Change incursions from Darfur into eastern Chad. Yamamoto is the first official in any government outside of Chad to repeat this claim, saying, "It is evident that there was safe haven and logistical support provided to rebel groups."[8]

Chad produces around 100,000 bpd (barrels of oil per day, 2013 figures) which travels through the Chad-Cameroon pipeline, owned and operated by US companies ExxonMobil and Chevron and Malaysian Petronas. The Déby administration threatened to cut off the supply of oil at the end of April if the international community did not intervene to end the rebellion or if Exxon Mobil did not pay the government $100 million.[9] The dispute was later resolved, and Chad's oil continues to flow to other countries.

Yamamoto tried unsuccessfully to convince President Déby to delay the upcoming presidential election which was held on May 3. He later said, "We held a very direct and private discussion on the issue [of whether to postpone the election]... When people say that it's too late to delay an election... it's never too late to do anything. We must focus on what is important... to have a process in place and actual ability of all the people to participate in the process. Any election that doesn't have full participation of all groups then raises issues that they would have to answer for."[10]

Yamamoto met with Ethiopian Prime Minister Meles Zenawi on April 22, 2006, to discuss the ongoing process of democratization in Ethiopia and the Ethio-Eritrea boundary dispute. Both leaders were positive about the outcome of the meeting.[11]

Yamamoto became acting Assistant Secretary of State for African Affairs on March 30, 2013, replacing Johnnie Carson.[12]

On 14 July 2018, President Donald J. Trump nominated Donald Yamamoto as the United States Ambassador to Somalia.[13][14] Yamamoto was subsequently confirmed for the position on 19 October 2018.[15][16] While the US Mission to Somalia is based on the grounds of the US Embassy in Nairobi, Kenya, a permanent diplomatic mission was established in Mogadishu in December 2018.[17][18]
