Chien Foo (Chinese: 錢復; born 21 March 1935), also known by his English name Fredrick Foo Chien, is a Taiwanese diplomat and politician who served as the president of the Control Yuan from 1999 to 2005. After earning his doctorate from Yale University, he assumed a series of governmental positions include Director-General of the Government Information Office from 1972 to 1975, Republic of China Representative to the United States from 1982 to 1988, Chairman of the Council for Economic Planning and Development from 1988 to 1990, and Minister of Foreign Affairs from 1990 to 1996. He was also the Speaker of the National Assembly between 1996 and 1999.

Chuen was born in Peking's Shou Shan Hospital, a hospital of the Peking Union Medical College, on March 21, 1935 (February 17 on the lunar calendar). His family's ancestral home was Hangzhou, Zhejiang. Chien's paternal grandfather, Chien Hong-Yeh, was a Chief Judge of the Criminal Court in Shanghai. Chien's father, Chien Shih-Liang, was a chemist and educator, and the former President of the National Taiwan University and Academia Sinica. Chien's mother was Chang Wan-tu.

In the fall of 1937, at the age of two, as the Second Sino-Japanese War broke out, his family moved to Shanghai to live with his paternal grandfather. His grandfather was assassinated during the Wang Jingwei regime in July 1940 after refusing to go along with a Japanese attempt to control the court system. After the war ended, his family moved back to Peking, where his father became the chair of Peking University's Chemistry Department at the invitation of President Fu Ssu-nien. With the Chinese Civil War, his family moved to Shanghai in mid-January 1949 and then to Taiwan with the Nationalist Government in mid-February.

In Taiwan, Chien was a student at Jianguo High School, where he graduated in 1952. He attended National Taiwan University as an undergraduate, graduating in 1956 with a bachelor's degree with honors in political science. During his time at the National Taiwan University, he was elected as the president of the student government [zh] and held the first Model United Nations conference in Taiwan. He also joined the China Youth Corps, where he visited Turkey and Spain in 1955. Chien passed the foreign service examination in 1956.^{[citation needed]}

After completing his conscription, he pursued advanced studies in the United States, first earning an M.A. degree from Yale University in New Haven, Connecticut, in 1959 and then a Ph.D. in international relations from Yale in 1962. His thesis examined Qing dynasty diplomacy toward Joseon Korea during the late 19th century, covering the period from 1876 to 1885.

Chen was engaged to Julie Tien on September 16, 1961, with Madame Hu Shih presiding over the ceremony in New York. On September 22, 1963, the couple were married at Taipei's Armed Forces Officers Club with Wang Yun-wu officiating their marriage.^{[citation needed]}

Upon returning to Taiwan in 1961, Chien interned at the Ministry of Foreign Affairs for three months and subsequently joined the Ministry in early 1962. Within months, he transferred to the Executive Yuan, as a secretary and the English interpreter for Premier and Vice President Chen Cheng. Chien also served as the English secretary and interpreter for President Chiang Kai-shek from 1965 to 1975. Chien recalled frequently serving as an interpreter for President Chiang Kai-shek and said the experience gave him valuable exposure to international leaders.

In 1963, Chien was awarded the 1st Annual Ten Outstanding Young Persons Award of the Republic of China along with other figures such as businessman Wu Yao-ting and politician Peng Ming-min.^{[citation needed]}
