Beijing - Amnesty International on Saturday said it feared China planned to execute a man convicted of spying for Taiwan and sentenced to death 18 months ago.
A Beijing court this week asked the family of former medical scientist Wo Weihan to apply to visit him within seven days after denying them access for nearly four years, the London-based group said in a statement.
"This sudden move suggests that the Supreme People's Court has approved the death sentence and that the Beijing Municipal Higher People's Court is preparing to execute Wo Weihan," the group said.
Wo, 59, was sentenced to death in May 2007 for spying after a closed trial, losing an appeal in February.
