In this paper I position the history of Korean mineral resources research with the background of the history of international relations by looking at the Korea-Russia Joint Mineral Resources Research Center in Khabarovsk, Russia. The Korean government strived to create new relationships with the communist countries when ideological conflicts broke down between the U.S.A. and U.S.S.R. in order to increase its presence. "Northern Policy" of the Roh Tae-woo Administration began among a series of events including the successful hosting of 1988 Seoul Olympics, the dissolution of the Soviet Union, and the efforts to transform North Korea-South Korea tensions. This paper focuses on how scientists discovered a new diplomatic space in the resources sector and expanded it by showing off their expertise and thereby contributing to science diplomacy. Scientists made efforts to become part of the government's policy to establish diplomatic relations with Russia and other communist countries by establishing natural resources issues as important policy issues. The Korean community of researchers, together with bureaucrats, strived to find a new space to realize a dream to survey minerals beyond national boundaries. In so doing, geoscientific knowledge and the boundary of Korean science were co-produced.
