As soon as the Russian Civil War broke out, Dmitry immediately sent a telegram to Arthur, inquiring whether to support Russia.
Arthur's response to Dmitry indicated that Australasia, due to major domestic construction, did not currently have much energy to focus on foreign affairs.
Arthur suggested that Dmitry should act according to circumstances, prioritizing the development of Finland and its interests.
Clearly, Dmitry took Arthur's advice to heart. Although he was the Grand Duke of Finland, Dmitry wasn't the sole decision-maker of the Finnish government.
Moreover, Finland's power was negligible in the context of the entire Russian Civil War; any help from Finland was more for show than practical use.
It was precisely this understanding, after being reminded by Arthur, that led Dmitry to focus on how Finland could emerge from the economic crisis, rather than paying attention to and supporting the Russian Civil War.
