The North Korean government took strong exception to the label, declaring that it would not return to six-party talks on the Korean nuclear weapons crisis until the United States apologized. On June 21, 2005, U.S. Under Secretary of State for Democracy and Global Affairs Paula Dobriansky used the term during a speech for the Hudson Institute: "North Korea, Burma, Zimbabwe and Cuba are outposts of tyranny." In response, the North Korean deputy ambassador to the United Nations Han Song-ryol stated, "Resuming the six-party talks would be possible if there is restraint on the part of the U.S. from using the words 'outpost of tyranny' for one month." South Korean Foreign Minister Ban Ki-moon was concerned over the implications for inter-Korean relations: "It is regrettable for a high U.S. official to call North Korea an 'outpost of tyranny', which is not good for the two Koreas' efforts to have a reconciliatory atmosphere."
