Arrests, Suspension of Vietnam Media Signal Crackdown An Hai WASHINGTON - A wave of arrests and a one-month publishing ban on a news site over its investigations into environmental damage signal that Vietnam is suppressing criticism ahead of the country's Party Congress, press freedom groups said. On June 12, authorities charged Le Huu Minh Tuan, from the Independent Journalists Association of Vietnam, with "opposing the state." Le is the fourth member of the association to be arrested since the group's founder, Pham Chi Dung, was detained in November. .
