Rockhill wrote a glossary of Salar in his 1894 book Diary of a Journey through Mongolia and Tibet in 1891 and 1892. During the administration of President of the United States Grover Cleveland, Rockhill served as Third Assistant Secretary of State from April 17, 1894, until February 13, 1896. He then served as United States Assistant Secretary of State under United States Secretary of State Richard Olney from February 14, 1896, until May 10, 1897. In 1897, President William McKinley named Rockhill U.S. Minister to Greece, a position he held from September 25, 1897, to April 27, 1899. He concurrently served as Minister to Serbia from May 7, 1898, to April 27, 1899, and as Minister to Romania from May 18, 1898, to April 27, 1899.

During the negotiations surrounding the Boxer Protocol, Rockhill argued against full war reparations, instead encouraging the Great Powers to settle for a lump sum of $333 million in reparations to be divided amongst the Powers in proportion to their expenses incurred in intervening in China. At Rockhill's urging, the American share of war reparations was used to fund student exchanges between China and the U.S.(a program known as the Boxer Indemnity Scholarship Program). In 1905, President Theodore Roosevelt appointed Rockhill U.S. Minister to China, a position he held from June 17, 1905, until June 1, 1909. This appointment came in the wake of the British Expedition to Tibet (1903–1904) that had forced Thubten Gyatso, 13th Dalai Lama into isolation. Learning that Rockhill spoke Tibetan, the Dalai Lama entered into a
