Which nation has General Dong Jun, who was recently in the news, as its minister of defense?

General Li Shangfu, who abruptly and mysteriously vanished from public view four months ago, has been replaced as China's new defense minister by General Dong Jun. Dong Jun, 62, was formerly the deputy commander of the Southern Military Command, which was in charge of the strategically important South China Sea region. He has experience in the Navy. Given the escalating hostilities with the US and Taiwan, the appointment of this loyalist to lead the People's Liberation Army, which numbers 2.3 million soldiers, is considered a major move by President Xi Jinping.
