Christopher William Dell is a career United States Foreign Service officer who currently serves as the United States Ambassador to the Republic of Kosovo. On May 27, 2009, President Barack Obama nominated Dell to be Ambassador to the Republic of Kosovo. Christopher William Dell was confirmed by the United States Senate to be the U.S. Ambassador to the Republic of Kosovo on July 10, 2009 and sworn-in on July 31, 2009.
Dell was appointed US Ambassador to Zimbabwe on July 2, 2004, and presented his credentials in Harare on September 2. During his tenure, the government of President Robert Mugabe has carried out Operation Murambatsvina, which has been described by Mugabe as an “urban renewal” programme and by his political opponents as a crackdown on the urban poor. Western governments, including that of the United States, have condemned it.
Relations between the United States and Zimbabwe have deteriorated as a result of both Operation Murambatsvina and the humanitarian situation in the country, which the United States has blamed on official corruption and mismanagement. In addition, the US named Zimbabwe an abuser of human rights in 2004 annual report. 
As a result of tense relations, Dell has borne the brunt of the Zimbabwe government’s displeasure. In mid-October 2005, he was detained for entering a restricted area of the Harare Botanical Gardens . A few weeks later, at a public lecture in the city of Mutare, Dell blamed corruption for the food shortages in the country, which the Zimbabwe government blames on foreign sanctions. On November 8, 2005, Dell was summoned to meet President Mugabe and was told to “go to hell.”   The following day, the ambassador was recalled to the United States for consultations.  He subsequently returned.
On March 19, acting on orders from President Mugabe, Foreign Minister Simbarashe Mumbengegwi summoned Dell and other western diplomats to his ministry to receive an official warning to stop interfering in the country's internal affairs. When Mumbengegwi refused to allow the diplomats an opportunity to ask questions, Dell walked out, describing the meeting as a "sham" for the benefit of the state media, who were filming the proceedings  . Dell left Harare the same day for London. The State Department stated that he would return to Zimbabwe soon. 
On July 14, 2007, Dell left his posting in Zimbabwe without bidding Mugabe farewell. According to Zimbabwean state radio, at the time of his departure he was disappointed because Mugabe remained in office. Dell was then appointed deputy chief of mission in Afghanistan.
