His ashes were deposited near the mausoleum in Carol Park, but his and all other remains at the complex were removed after the Romanian Revolution of 1989. Found and preserved by the World Jewish Congress, his documentary collection is housed in New York City. The writer was survived by son Alexandru. In 1956, he had been the Deputy Foreign Minister, in charge during the absence of Minister Preoteasa. He became noted for his unorthodox response to the Hungarian anticommunist revolt, which he described as a "necessary process of democratization", though both he and Preoteasa were involved in the effort to contain its spread into Romania. Later a Head of Department, Lăzăreanu Jr was instrumental in obtaining Romania's affiliation to UNESCO and the United Nations. He died in Bucharest in October 1991, almost two years after the fall of Romanian communism.
