The role of energy in Iran-Turkey relations / Omid Shokri Kalehsar. (OCLC #873602124)
After reviewing the differences between the free-floating subdivisions –Relations, –Foreign relations, and –Military relations, I assigned this heading:
Iran ǂx Foreign relations ǂz Turkey.
When one of these relations subdivisions is further subdivided geographically, you need an additional heading with the geographic terms reversed (SHM, H 1629) so I assigned this one as well:
Turkey ǂx Foreign relations ǂz Iran.
