However, per capital income in China's rural areas remains at levels about one-third of that in the cities. When considered together with the various forms of discriminatory treatment that farmers face, such as social welfare, the income gap between China's urban and rural areas is the largest in the world. And this situation may become a cause of social instability if left unsolved. The administration of President Hu Jintao and Premier Wen Jiabao has positioned the resolution of the "three agriculture-related problems" --- agriculture, farmers and rural villages --- as a top matter since taking office.。
