BEIJING - A majority of Chinese polled in a recent survey believe widespread corruption and public discontent are to blame for social uncertainties in the country.

Even though China's economy has maintained a steady growth, people are worried the country would fall into a "middle-income trap" and suffer from economic stagnation and various social problems, according to a poll launched by a magazine affiliated with People's Daily.

China's GDP per capita reached $3,600 in 2009, pushing the country in the list of middle-income nations.
