Coordination of technical standards is probably the most routine sort of international relations. Everyone can agree that it is useful when phone calls and letters can successfully operate across international borders, and that it is useful when roads, rail lines, electrical connections, and other linkages are available and standardized.
The practicality of these tasks aside, it does seem probable that they would help to foster good relations between countries. When engineers from Country X see that engineers from Country Y are a lot like them, it is plausible that they generalize that feeling into a certain sense of general commonality.
It would be interesting to see some data and analysis on the role technical cooperation has played in fostering good relations. Routine work like communication interlinkages could be one topic of study. The same could be true for more exotic undertakings, like joint space missions.
As discussed before, it is also possible that the existing level of cooperation between states could break down if the world became sufficiently unstable.
