The wife of a Princeton University graduate student imprisoned in
Iran said Thursday that her husband is not a spy as she appealed for international cooperation to secure his release.
"I plead for the gate of mercy to be opened for him, and I hope he can come back to us as soon as possible," Hua Qu said in a speech marking the third anniversary of her husband's detention.
Hua also said there have been no recent productive conversations between the
United States and the Iranian government about Xiyue Wang, a Chinese-American history researcher who was sentenced to 10 years in
prison after being convicted of "infiltrating" Iran and sending confidential material abroad.
