Fishing boat in Da Nang, Vietnam
Vietnam's media is full of tales of fishermen being mistreated by China
Nguyen Thi Buoi is an unhappy woman these days.
Her husband, Tieu Viet La, and her two sons are among the 12 fishermen from Binh Son district in Quang Ngai province arrested on 22 March by a Chinese fishing patrol for "infringing Chinese waters".
Mr La and the others say they were caught as they were sheltering from a looming monsoon near Woody Island, the largest in the Paracel archipelago, occupied by China in 1974 but also claimed by Vietnam.
Since his arrest, his family have received only one phone call from him, urging them to pay a "fine" of 180m dong ($ 9,500:£6,000) demanded by his captors.
"We don't have any money," Mrs Buoi says, tears running down her face. "So far, I have only managed to secure 40m dong."
In recent months the plight of the Quang Ngai fishermen has received huge coverage in Vietnam's state-run media. The full story here.
