You are introducing a straw-man argument here (that obviously ignores basic facts about population sizes of Sweden and China, so it's wrong on both meta- and object-level). But following that line of reasoning, Sweden is not an ethnostate because the Swedish population is ethnically diverse. E.g., more than a third of the population are either foreign-born or have at least one foreign-born parent. At the same time, the current borders of Sweden cover more than the traditional homeland of your preferred "Swedes". So apparently, you are actually arguing for a racist empire. Demographic reality is not your friend, though. Perhaps you will have more success some generations down the road. Try to sell the same story to the ethnically substantially different group of people who will consider themselves "Swedes" then.
