President Obama silent on China activist at news briefing
US President Barack Obama has refused to comment on Chen Guangcheng, the Chinese dissident said to be at the US embassy after fleeing house arrest.
Mr Obama told a news conference he was "aware of press reports" on the issue, but would not make a statement on it.
But he said: "Every time we meet with China the issue of human rights comes up".
Activists claim Mr Chen entered the US embassy in Beijing earlier this month, after slipping out of his home.
US and Chinese officials are thought to be in talks on his fate.
