About Wo Weihan
Lived 1949 – 2008 (aged 58–59). Wo Weihan was a biologist, biochemist, spy, biophysicist, businessperson and biomedical researcher.
Wo Weihan (; 1949 – November 28, 2008), a native of Qiqihar, Heilongjiang, was a Chinese scientist and entrepreneur of Daur nationality. He was executed at the age of 58–59 on November 28, 2008, by firing squad, along with missile expert Guo Wanjun, 66, for passing sensitive information to a Taiwanese NGO. Weihan was interrogated for ten months in 2005 and allowed access to a lawyer in 2006. His trial was held in secrecy in 2007.
Charges The case against Wo related to alleged passing of sensitive national security information, which China argued justified special handling of the case.
It was claimed that Wo became a spy for Taiwan intelligence agency with the codename "YANG DONG". He got to know Mr Guo during a wedding ceremony in early 1990s. The Taiwan intelligence agency also invested (USD) $300,000 to help Wo's first wife, to set up a restaurant in Austria. She said that Wo's arrest and trial had fallen short of international standards for due process. “Reportedly Mr Wo did not have access to legal counsel until after the prosecuting officials completed their investigation. His confession was coerced and the charges against him were questionable.”
Their executions came at a time when China had been presenting itself as a reformed and more humane state, particularly on the eve of China's Olympic debut. The EU and US response to the executions indicate that the executions severely challenged the credibility of the SPC death penalty review reform, which aimed to reduce the number of executions in China (estimated at 7000 per year). Wo's two daughters, both Austrian citizens, resorted to Austria and EU to first request a fair and transparent trial for their father, and later pleaded for amnesty as the deficiencies in the prosecution of the case became clear. Diplomatic efforts made behind the curtains had no result for three years. Media coverage and an expanded advocacy campaign which included pleas by Condoleezza Rice, President Heinz Fischer of Austria and the EU Troika were also in vain.
Family Wo Weihan's wife and younger daughter saw Wo Weihan on the morning of November 27. None were given official confirmation that the sentence had been approved and that an execution was pending. Wo's elder daughter expected to be able to see her father that week after the Chinese Ministry Foreign Affairs promised to the Austrian Embassy in Beijing that a second visit would be allowed for her. However, Wo was executed on the morning of November 28. This led to very strained relations between the Austrian and Chinese Ministries of Foreign Affair; Austria viewed it as an intentional affront.
According to Qin Gang, the spokesman of the Ministry of Foreign Affairs,".....Wo Weihan is a Chinese citizen.... He could not be treated in a different way only because he has some foreign relatives."
Guo's family were not allowed to visit Guo during the years of imprisonment, and only five days after the execution, which they had found out about through Wo's family, did they receive a notice that they could pick up Guo's ashes.
