CIRA China analyst John Chen and CIRA head James Mulvenon authored a chapter in the recent conference volume The People in the PLA 2.0 regarding PLA foreign training exercises:
The People’s Liberation Army’s (PLA’s) top leaders recognize that the quality of its personnel is a vital component of its efforts to become a more effective fighting force and its accelerated preparations to fight and win wars.

President Xi’s call to improve the PLA’s personnel quickly filtered down through various levels of the PLA: soon after the Work Report, service-level party committees (党委) charged with force construction and personnel development issued specific documents detailing how they plan to implement the Chairman’s goals.
