"The economic reforms and related government policies unleashed spectacular economic growth. As China’s economy rapidly expanded, so did its need for energy, and after 1993 China dramatically increased oil imports. The booming economy permitted some citizens to become enormously rich while drastically reducing the percentage of the country’s people living in poverty. It also led to major environmental problems. Partly because China has made enormous economic progress and has improved the lives of the large majority of its people, the government appears to enjoy significantly more popular support currently than it did in the late 1980s. Contemporary public protests center on issues that have arisen from economic reforms or have resulted from the accompanying excesses and corruption. Many demonstrators appeal to national officials for help in combating local problems, and in recent years the central government has responded with policies to address some of their major concerns, like improving conditions for people migrating from rural areas to cities and reducing air and water pollution. Political change in China, including democratization, appears to be an ongoing but long-term process."
