Both Mao Zedong and Deng Xiaoping drastically altered the course of contemporary China's economic development using opposing strategies. Mao froze China's economic system in a perennial state of consumer goods shortages and pervasive macro disequilibria. Deng, however, began thawing a rigidly structured system by introducing experimental reform measures. Mao's revolutionary rhetoric brought China's economy to the brink of bankruptcy. Deng's ideological pragmatism netted China glowing successes. Mao closed China to the outside world. Deng engineered China's reintegration into the world economy.
