The People's Republic of China announced the appointment of a new defense minister on Friday, filling the gap left by his predecessor's termination. 

Former naval commander Dong Jun was selected for the position, which is generally a ceremonial role. 

Unlike in most countries, the defense minister of China is not in command of the nation's armed forces, the People's Liberation Army. 

Instead, Dong is stepping into an office more focused on diplomatic responsibilities.

CHINA OUSTS FOREIGN MINISTER WHO HAS BEEN MISSING FOR A MONTH

The ministry of defense office has been vacant for months after the mysterious termination and disappearance of the previous occupant, Li Shangfu. 

Li was last seen on August 29 in Beijing, where he delivered an address at the China-Africa Peace and Security Forum.

CHINESE DEFENSE MINISTER NOT PUBLICLY SEEN FOR AT LEAST 2 WEEKS: REPORT

Li's disappearance is believed to be part of a larger upheaval of military officials, financial advisers and diplomats. 

Foreign Minister Qin Gang was among the highest-ranking and most public figures to have been removed from office around the same time. 

In a July announcement, Chinese state media gave no reason for Qin’s removal. The move comes after he dropped out of sight almost one month ago amid speculation over his personal affairs and political rivalries, according to the Associated Press. 

The reason for the conspicuous terminations is the source of significant speculation among foreign analysts.

Corruption and insufficient displays of loyalty to President Xi Jinping are among the most accepted explanations, but the Chinese Communist Party's fierce internal secrecy has kept the matter opaque to outside observers.
