Beijing: Tibetan author Tsering Woeser and her Chinese husband and fellow author, Wang Lixiong, have been placed under house arrest in Beijing since the outbreak of anti-Chinese protests in Tibet.
"Whatever movements we plan to make, we must first ask for approval," Wang told the US-sponsored Radio Free Asia. "Only when it's approved by higher-ups can we make a move under surveillance."
He had previously been a focus for Chinese authorities, but now the focus has shifted to his wife, who declined to be interviewed for fear of repercussions.
Tsering Woeser, 40, has written 10 books, including two on China's Cultural Revolution. Most of her work has been banned inside China. Her blog was blocked by authorities last year after she published a photo of the Dalai Lama.
The couple regularly makes contributions to Radio Free Asia's Chinese programme.
