US President Barack Obama landed in Shanghai on Sunday evening at the start of a four-day state visit to China, the New York Times reported. He is scheduled to meet with Shanghai party chief Yu Zhengsheng, and later meet with university students in a "town-hall" meeting before flying to Beijing for meetings with Hu Jintao and Wen Jiabao. Economic issues are expected to be the focus of his visit. Speaking in Tokyo last week, Obama said the US would not seek to contain China’s economic rise. "The rise of a strong, prosperous China can be a source of strength for the community of nations," he said.
