Can you think of another example of a non-European nation taking inspiration from the age of imperialism? Do?

Explanation:

In the heyday of empire, most of the world was ruled, directly or indirectly, by the European powers. On the eve of the First World War, only a few non-European states had maintained their formal sovereignty: Abyssinia (Ethiopia), China, Japan, the Ottoman Empire, Persia (Iran), and Siam (Thailand). Some others kept their independence for a while, but then succumbed to imperial powers, such as Hawaii, Korea, Madagascar, and Morocco. Facing imperialist incursion, the political elites of these countries sought to overcome their political vulnerability by engaging with the European powers and seeking recognition as equals.
