The Wenzhou procuratorate in Zhejiang province has approved the arrest of Yang Chih-yuan on suspicion of splitting the country, according to a statement issued by the Supreme People's Procuratorate on Tuesday.

The national security bureau in Wenzhou has concluded the investigation into the case of Yang, a resident of Taiwan, and has transferred it to the Wenzhou procuratorate for examination and prosecution, the bureau said.

In August 2022, the Wenzhou national security bureau detained and investigated Yang, who has long been engaged in "Taiwan independence" separatist activities.

Yang, born in 1990, is a native of Taiwan's Taichung. He has long advocated the idea of "Taiwan independence". Together with others, he set up the "Taiwan national party", with the goal of "promoting Taiwan to become a sovereign and independent state and join the United Nations", and planned and carried out separatist activities for "Taiwan independence", according to a previous official statement.
