Robots and automation will help China maintain its position as the world's factory and dominant exporter. However, robots will not be able to replace consumers in China's consumer market (after all, robots do not consume, they only produce); hence, China will either need to boost the number of consumers, or boost the individual purchasing power for each consumer, to ensure its large consumer market can keep growing. Otherwise, robots will only help insofar as growing manufacturing exports to other markets, and I'm pretty sure the government is keen to avoid the dangers of increasing export dependency.
