・Japan, which succeeded in separating the Korean Peninsula and Taiwan from the Qing sphere of influence due to the Sino-Japanese War, did not have a foreign policy of joining hands with Qing to oppose the colonialism of Western powers, and found rationality in a foreign policy that eliminated the influence of major continental powers on the islands and peninsulas as a maritime nation (p127)

Therefore, Putin annexed Crimea and carried out military complicity in separatist movements in the eastern region (p191)
