Consider the trajectory of Singapore. Founded around 1820, the city grew around cohorts of European, Indian, Arab, Malay, and Chinese immigrants.

wikipedia describes the Singapore town plan of 1822.

Now, according to the CIA world factbook, Singapore is 77% ethnic Chinese. There was never any plan, never any violence. It just worked out that way.

Talk of secret plans etc. is silly. That’s not the way things work. China is thriving and war and conquest is no part of the recipe.
