WARSAW, Poland (AP) — Two men accused of spying for China have gone on trial in Poland’s capital. One is a Chinese citizen who is a former sales director of Huawei in Poland and the other is a Polish cybersecurity expert who had worked for a national security agency. Both have pleaded not guilty. Prosecutors requested that the trial be held in secret due to the classified nature of some of the evidence. Although the defendants objected, the court agreed, citing state interests. Both men face criminal charges of taking part in a foreign intelligence operation and threatening Poland’s interests. If convicted, they face a minimum of three years in prison.
