Taiwan is monitoring what it called "abnormal" changes to China's military leadership after its most senior general was put under investigation, and will use various methods to decipher Beijing's intentions, Defence Minister Wellington Koo said on Monday (Jan 26), Reuters reported. 

China announced on Saturday that Zhang Youxia, second-in-command under President Xi Jinping as vice-chairman of the Central Military Commission, and another senior officer, Liu Zhenli, were under investigation for suspected serious violations of discipline and law.

"We will continue to closely monitor abnormal changes among the top levels of China's party, government, and military leadership. The military's position is based on the fact that China has never abandoned the use of force against Taiwan," Koo told reporters at parliament, according to Reuters.
