Description:President Barack Obama on Monday (April 30) ducked a question about a Chinese dissident believed to be under U.S. protection in Beijing but said China will be stronger if it improves its human rights record. At a news conference with Japanese Prime Minister Yoshihiko Noda, Obama appeared to be walking a fine line between not saying anything to make it harder to resolve Chen Guangcheng's case while conveying U.S. respect for human rights and U.S. appreciation for wider cooperation with China.(1:14)
