Why did parts of europe and north america develop industrialized economies in the early 19th century while prominent empires like china did not?

Europe and North America used different tactics such as slavery and trade to industrialize and blossom into more powerful empires. The Chinese had many factions and rifts within themselves thus not thinking and seeing themselves as one strong country while the Europeans and Americans weren't divided and thought of themselves as one people. This also led to the growth of development and human enhancement
