Taiwan's news agency CNA (The Central News Agency) on April 17, 2017, reported that China's Ministry of Environmental Protection sent internal orders to environment monitoring stations in Northeast China to establish 24-hour on-duty monitoring schedules for radioactive pollution signs. The scope of the internal orders covers the provinces of Jilin, Liaoning, Tianjin, Hebei and Shandong. According to leaked internal information, the Chinese government expected the upcoming sixth North Korean nuclear test to be several times the scale of the fifth. There is a good possibility that the North Koreans may test some new technologies, which have a higher risk of failure. Also, over 200 high ranking military officials were called to report to the Northern Military Theater Joint Command Center. The Military Theater has already come up with several detailed combat plans to respond to the North Korean crisis.
