Liberty unlocks a people's full potential: Biden

CHENGDU: US Vice President Joe Biden said Sunday China should "cherish" the exchange between its citizens and the government, following the toughest crackdown on Chinese dissidents in years.

"China should cherish an exchange between its citizens and students and their government," Biden told hundreds of university students in the southwestern boom town of Chengdu on the final day of a visit to China. "Liberty unlocks a people's full potential and in its absence, unrest festers."
