Chuon Ming Lo, 61, proprietor of the Peking restaurants here and a leader in Washington's Chinese Community, died of cancer Friday at Georgetown University Hospital.

He came to Washington in 1941 and opened the first Peking restaurant uptown on Connecticut Avenue in 1947. Other restaurants followed at 13th and G streets NW (which closed in 1977), in Fairfax, and at 15th and I streets NW.

Mr. Lo was president of the Chinese Consolidated Benevolent Association in 1971.

He was president of the Yeng Kiang Association, one of 17 business groups that form a senior council in Washington's Chinese community, and was the official spokesman for the council.

A former mayor of Chinatown here, Mr. Lo, who was known as "C.M.," gave much of his time to helping immigrant Chinese adjust to their new environment. He arranged for their employment, housing and personal needs.

He was born in Gyanzhou, China. He went to work in the diplomatic service of the Republic of China at the age of 18, and was a chef to China's ambassadors to Russia, Poland, Germany, Switzerland, Portugual, Spain, France and Denmark before coming here.

M. Lo, who lived in Washington, was a member of the Chevy Chase Presbyterian Church, the Yeng Kiang Chinese Opera Club, the Chi-Am Lions Club, the Chinese Consolidated Benevolent Association and the Metropolitan Washington Board of Trade.

He is survived by his wife, Sophie Chang Lo of Washington; three daughters, Lilly Fong of Los Angeles, and Merry Yim and Virginia May Lo, of Washington, and a brother, Chuon Yuan, of China.
