Konrad Bekker, 70, a retired State Department and Foreign Service official who specialized in Asian affairs, died of an apparent heart attack Friday at his summer residence in Mathias, W, Va. He lived in New York City.

Mr. Bekker, who was born in Berlin, Germany, was educated in Germany and Switzerland. He came to the United States in 1938 and spent about a year at the Brookings Institution in Washington. He then taught economics at the University of Kentucky.

During World War II, he went into the Army and received Japanese language training. He was assigned to the Office of Strategic Services, a forerunner of the Central Intelligence Agency, and served with it in Ceylon.

After the war, he returned here and in 1946 joined the State Department. He later became a Foreign Service officer. His assignments abroad included India, Burma, Thailand and Switzerland. He retired in 1971.

The following year, Mr. Bekker was named director of meetings and studies at the Asia Society in New York City. He retired a second time in 1976.

He was a member and the treasurer of the Society for Asian Music.

Mr. Bekker's survivors include his wife, Sarah McInteer Bekker, of Mathias and New York City.
