Statements:
I. China’s economic shift was motivated by a need to address a period of stagnant growth.
II. The implementation of Special Economic Zones (SEZs) helped integrate China into the global manufacturing chain.
III. The benefits of the "Four Modernizations" were distributed uniformly across China’s geographic regions.
