Vacancy Lasted More Than Two Years
U.S. President Donald Trump has nominated veteran diplomat Christopher Anderson to serve as the next United States Ambassador to Cambodia, ending a vacancy that has lasted for more than two years and potentially signalling a new phase in Washington’s engagement with Phnom Penh.
The White House announced on June 1 that Anderson, a career Foreign Service Officer from Wisconsin, had been nominated as Ambassador Extraordinary and Plenipotentiary of the United States to the Kingdom of Cambodia. The nomination has been submitted to the U.S. Senate for confirmation.
The ambassadorial position has remained vacant since May 18, 2024, when former Ambassador W. Patrick Murphy concluded his nearly five-year tenure in Cambodia.
Veteran Diplomat Brings Extensive International Experience
Anderson has served in the U.S. Foreign Service since 2005 and has held several senior diplomatic assignments. He previously worked at the U.S. Embassy in Kyiv from 2014 to 2017 before serving as Special Adviser for Ukraine negotiations between 2017 and 2019.

Much of his recent diplomatic career has focused on Eastern Europe and Ukraine-related policy issues, giving him experience in navigating complex geopolitical environments.
His nomination follows an unsuccessful attempt by the Biden administration to fill the role. Robert William Forden, a former Deputy Chief of Mission and Chargé d’Affaires at the U.S. Embassy in China, was nominated but never ultimately took up the post.
Appointment Comes As Bilateral Relations Improve
The nomination arrives during a period in which Cambodia and the United States have been working to strengthen diplomatic and economic engagement after several years of strained relations.
Him Rotha, Deputy Director of the Cambodian Centre for Regional Studies, noted that relations between the two countries are currently undergoing a process of recalibration.
While embassy operations continued under interim leadership during the vacancy, analysts suggest the appointment of a Senate-confirmed ambassador could provide greater momentum for diplomatic engagement, trade discussions and broader cooperation initiatives.
If confirmed, Anderson would become the first U.S. ambassador to Cambodia since Murphy’s departure and take up the position at a time when both governments are seeking to expand dialogue across political, economic and strategic areas.
