I know that the answer to the question "what had effect on the nation that was not colonized?" is in "The Dutch East India Company (1800) and British East India Company (1858) were dissolved by their respective governments, who took over the direct administration of the colonies. Only Thailand was spared the experience of foreign rule, although, Thailand itself was also greatly affected by the power politics of the Western powers. Colonial rule had a profound effect on Southeast Asia. While the colonial powers profited much from the region's vast resources and large market, colonial rule did develop the region to a varying extent.". Can you tell me what it is?
A:
power politics of the Western powers
