The military commander of Hainan, Major General Tan Benhong, is to replace Lieutenant General Wang Xiaojun as head of the People's Liberation Army's Hong Kong garrison.
Tan, 57, has led the Hainan military command, which comes under the greater Guangzhou military area command, since April 2012. He was chief of staff of the Hong Kong garrison from May to August 2007.
Hong Kong garrison spokesman Liu Fengxian confirmed that Wang, 62, would be appointed deputy commander of the Guangzhou military area command, one of seven main PLA jurisdictions, Xinhua reported.
Tan said he would "carry out defence responsibilities … and contribute to Hong Kong's prosperity and stability by working together with Hong Kong people". Wang thanked Hongkongers for their support, a military spokesman said.
Wang had led the Hong Kong garrison for only 21 months. He was promoted to lieutenant general three months before his Hong Kong appointment in October 2012.
Wang was promoted to PLA commander of Hainan in March 2004 and served in different positions with the Guangzhou military area command before he was promoted to deputy commander of the Shenyang military area command in 2010.
In Hong Kong, Wang had replaced Lieutenant General Zhang Shib, 62, as garrison commander after Zhang was promoted to commander of the Beijing military area command.
Zhang had replaced Lieutenant General Wang Jitang, 68, as commander of the Hong Kong garrison in January 2008. At the time Wang had been in the post since January 2003.
Senior positions at the Hong Kong garrison have long been regarded as stepping stones in officers' careers.
Meanwhile, Major General Chen Zhaohai, formerly the deputy commander of the Jinan command, has been named deputy commander of the Guangzhou command and was promoted to lieutenant general on Sunday, news website Caixin.com reported.
He was head of military training for the General Staff Headquarters before his promotion to the Jinan command last year. Besides Chen, 10 generals from the Guangzhou command were promoted to major general and lieutenant general on Sunday.
