On August 1, China held the Celebration Party for the 90th Anniversary of the People’s Liberation Army (PLA) at the Great Hall of the People in Beijing. Xi Jinping gave an important speech.
All of the seven Communist Party’s Politburo Standing Committee members and current high-rank military and Party officers sat on the rostrum. However, none of the retired officials, from either the military side or the Party, was seated on the rostrum. This is totally different from the 70th or the 80th anniversary celebration where the retired officials were on the rostrum.
A political commentator suggested that this showed Xi has full control of the military, exceeding what the previous leaders had.
