Gao Yu appealed her April conviction for leaking state secrets at a closed hearing on Tuesday at Beijing's high court. Her lawyer Shang Baojun said the court announced today that her sentence would be reduced.
Gao was convicted of sharing with an overseas news magazine a document detailing the Communist Party leadership's resolve to aggressively target constitutionality, press freedoms and groups that seek to change society but operate outside the party.

"We make this request out of consideration for the Party cause, out of consideration for the nation and its people-and also out of consideration for your personal safety and that of your family," the letter published by a host of foreign media including the BBC said.
A well-known Chinese dissident Wen Yunchao living in the US said three members of his family including his parents and brother, living in China's Guangdong Province, had also been detained in connection with the letter, the BBC report said.
His relatives were held after a US-based blogger Liu Gang said in an online post Wen was also behind the letter. Since then his family is being harassed, Wen said.
