Li’s disappearance follows the surprise removal of foreign minister Qin Gang from his post in July, also after a weeks-long disappearance. There has been no further information or sign of him since.

In China’s political system ministers are not the highest ranking in a particular portfolio. As defence minister, Li reports to two vice-chairmen in the central military commission, who then report to Xi. However he is also one of five state councillors, which ranks higher than a regular minister. Qin remains a state councillor.

I dont know how things work in China, but in normal countries, these positions are considered two of the most important ministerial positions. Xi is cleaning house. If it is for corruption reasons, wouldnt the chinese state brag about it?
