As per the Taipei Times on Wednesday, Taiwan's High Prosecutors' Office has charged retired army lieutenant general Kao An-Kuo and five others with national security crimes, such as forming an organisation in Taiwan to assist China in the event of a military invasion. The office said the six defendants were charged with violating the National Security Law and were moved to Taiwan's High Court. The court ruled to imprison them and ban any outside contact.

According to a press release, Kao An-kuo founded a pro-government group called the "Republic of China Taiwan Military Government" after being retired from the military. Kao, along with a military spokesperson who is surnamed Hou and a woman surnamed Liu, was recruited by the Chinese intelligence agents in 2019 after several exchanges.

The prosecutors said that Hou and Liu are two suspects in taking financial support from the Chinese military to form armed organisations and operational bases in Taiwan. According to the Taipei Times, the prosecutor stated the six accused received over 9.62 million New Taiwan dollars from China altogether.

Prosecutors said that Hou and Liu recruited former military colleagues in order to undermine the government, intending to back the Chinese military in the event of an invasion of Taiwan. They have asked the court to sentence Kao and Liu to at least 10 and eight years in prison, respectively, since their activities jeopardise national security and place it in unexpected circumstances.

According to the Taipei Times, prosecutors said that the other convicts should face prison sentences ranging from three years and five months to more than eight years. In 2021, Kao uploaded a video of himself wearing military fatigues, asking Taiwanese forces to hand over their forces to China and topple the Democratic Progressive Party (DPP) government.

In early December, Taipei prosecutors charged four former military officials for selling state secrets to China. The Taipei Times reported that the four men, identified as Lai, Lee, Lin and Chen, were imprisoned. The Taipei District Prosecutors' Office identified three suspects who were in charge of security at the Presidential Office Building: Lai, Lee, and Lin from the 211th Military Police Battalion and Chen from the Ministry of National Defence's Information, Communications, and Electronic Force Command.

"Lai served from August 2015 to November last year, Chen from December 2017 to July last year, Lee from 2018 to February, and Lin from 2021 to August. From the end of 2021 to the beginning of 2022, Lai and Chen were allegedly brought into the scheme by a man surnamed Huang, who is currently wanted, on behalf of China's intelligence agents," prosecutors stated.

"Starting in April 2022, Chen used his mobile to take photographs of classified documents before passing them on to Lai and Chen, or Chinese agents," prosecutors further stated. Further, prosecutors noted that last year, between March or April and this year’s August, by using a fake identity, Chen recruited fellow soldiers and lured them into providing rewards to spy on China.
