Also stepping down is Richard Richter, who has headed up Radio Free Asia for 10 years.
Richter, a journalist, will retire July 29. He was founding president of RFA and was appointed by the Broadcasting Board of Governors after a career as an executive producer with ABC, CBS and PBS television.
Vice President for Administration and Finance Libby Liu will serve as acting president.
RFA programs target listeners in "closed" East Asian countries in Burmese, Cantonese, Khmer, Korean, Lao, Mandarin, Wu, Tibetan, Uyghur and Vietnamese. Richter said in the announcement that RFA had overcome initial skepticism from other news organizations about its accuracy.
BBG Chairman Kenneth Y. Tomlinson said in a statement, "Few people in the history of international broadcasting have served with the intellectual honesty and the essential decency as Dick Richter."
