As a pro-business mayor of San Francisco in the 1980s, Feinstein worked intently to expand economic ties in the Pacific Rim, especially in China. She set out early in her tenure to establish sister city relations between San Francisco and Shanghai.
Feinstein and her counterpart in Shanghai at the time, Jiang Zemin, who is now China's president, agreed in 1986 to designate various corporate entities to foster trade and other business relations. One was named Shanghai Pacific Partners; Blum served as a director.
