Beijing( CNN) Chinese leader Xi Jinping is president of a major military procession Sunday, hours after US President Donald Trump renewed his criticism over Beijing’s failure to rein in North Korea.

The parade, long foreseen but merely officially announced Saturday, was part of the celebrations of the 90 th anniversary of the People’s Liberation Army( PLA ). It was also viewed as a potent reminder of Xi’s firm grip on power ahead of a key Communist Party meeting this fall, where a major leadership reshuffle is expected.

Unlike previous public displays of its developing military might, China held Sunday’s event at the remote Zhurihe military base in Inner Mongolia — instead of in the center of Beijing.
