Fukuda Doctrine
Takeo Fukuda was an expert in economics. He took on the role of an ‘economic prime minister’ under Miki's administration from 1974 to 1976. During this time, he established the Ministerial Conference on Economic Measures, enabling cross-ministry and agency talks on finance, wage and labor issues.
Fukuda subsequently became the 67th prime minister of Japan, lasting for only one term from 1976 to 1978. However, he was not forced out of office before he had gotten two major diplomatic reforms executed. Under Fukuda cabinet, Japan conducted an omnidirectional peace diplomacy, and signed Japan-China Treaty of Peace and Friendship in 1978. He pushed forward Japan's pacifistic position while making an effort to strengthen relations with Asian countries.
Sunao Sonoda
On 17 May 1981, Sonoda was appointed by then prime minister and his close friend Zenko Suzuki as foreign minister for the last time due to unexpected resignation of the former foreign minister Masayoshi Ito. Sonoda called for adopting the omnidirectional diplomacy and unlike his two predecessors, issued entry visas to Soviet economic delegations. Sonoda was replaced by Yoshio Sakurauchi who was appointed foreign minister by prime minister Zenko Suzuki on 30 November 1981. The reason for Sonoda's removal from his post was his blunt remarks concerning U.S. policies in June 1981 as well as his other statements detrimental to Japan's relations with South Korea.
