The national security bureau in Wenzhou has finished its investigation into Yang’s case and has transferred it to the Wenzhou procuratorate for examination and prosecution, it said.
In August, the Wenzhou national security bureau detained and investigated Yang, who the statement said has long been engaged in “Taiwan independence” separatist activities.
Yang, born in 1990, is a native of Taiwan’s Taichung. He helped set up the “Taiwan national party”, with the goal of “promoting Taiwan to become a sovereign and independent state and join the United Nations”, according to a previous official statement.
