An American woman has been held by authorities in China for the past six months accused of stealing state secrets, her husband has revealed.
Sandy Phan-Gillis’s husband Jeff Gillis said he decided to go public about her circumstances ahead of Chinese President Xi Jinping’s visit to the US.
China’s Foreign Ministry spokesman Hong Lei confirmed the investigation in a regular briefing on Tuesday.
The US government has not commented. Her family deny the allegations.
The New York Times reports that she has now been formally arrested, citing her husband and lawyer.
Mrs Phan-Gillis, a naturalised American born in Vietnam, was detained in March, during a trade visit to promote the Texan city of Houston.
According to Save Sandy, a website campaigning for her release, she has spent six months in so-called “residential detention”, which it equates to house arrest.
Her husband says she is now being moved to a more secure facility.
