China’s military has promoted two senior People’s Liberation Army (PLA) officers to the rank of general, a move seen as part of preparations to reorganize the top leadership structure after the thinning of ranks caused by a long-running anti-corruption drive.

At a ceremony in Beijing on Friday, Xi Jinping—who also heads the Central Military Commission—presented orders promoting Zhang Shuguang and Wang Gang.

Zhang Shuguang was also named head of the Central Military Commission’s division investigating corruption, reinforcing his role in the military’s top anti-graft apparatus. Wang Gang was promoted as commander of the PLA Air Force.

The promotions are also viewed as potential steps toward filling vacancies on the seven-member Central Military Commission, which has been reduced to two serving members due to corruption investigations and removals.

The article notes that the commission is chaired by Xi, with Vice Chair Zhang Shengmin also serving as a current member. It adds that two former vice chairmen, including the military’s top general, have been removed, and that a new commission is expected to be announced in the fall of the following year, at the end of the current five-year term.
