WASHINGTON (AP) _ Relatives living in the United States say Romania's new deputy foreign minister, Cornelieu Bogdan, has died in Bucharest.

Bogdan, 68, was Romanian ambassador to the United States from 1969 to 1977 and returned to Washington in 1988 where he lived until last month.

A stepdaughter who lives in Washington, Svetlana Hoge, said he died Monday, apparently of an aneurysm suffered while he was at work. She said he had a history of heart trouble.

Mrs. Hoge said Romanian officials notified relatives here by telephone from Bucharest.

After returning to Bucharest, Bogdan was out of government for a time but later was named to a post in the foreign ministry that gave him authority over Western Hemisphere relations, she said.

Mrsn Hoge said, however, that there was friction between her father and the government of dictator Nicolae Ceausescu and that he again left the ministry and was placed under what amounted to house arrest.

She said, however, he was allowed to travel to Washington in 1988 on a Woodrow Wilson fellowship and that he remained in the United States until a month ago.

Bogdan was born Nov. 5, 1921, into a Jewish family in Bucharest. Mrs. Hoge said he enrolled in the Polytechnical Institute in that city but was forced to halt his studies by the coming of fascism and World War II. She said he joined the Communist Party at about that time.

Besides Mrs. Hoge, survivors include his widow, Emilia Bogdan, and two daughters, Olga Bogdan of Washington and Illeana Popa of Bucharest.
