Two citizen journalists face trial in Vietnam today for operating pirate radio to China.  Vu Duc Trung and Le Van Thanh face charges of illegally retransmitting radio programmes after they began broadcasting Chinese-language programmes from Sound of Hope Network, a Chinese radio station based in California. According to a Vietnamese Public Security Ministry document, the programmes, which were critical of the Chinese government, were the subject of a note to the Vietnamese authorities, asking them to stop the broadcasts. The trial, which was due to begin today, has been postponed for the second time.
