China makes its military more visible in Hong Kong
For years after it took control of Hong Kong from Britain, China kept its military in the city on a low profile.
Its presence was largely symbolic and People's Liberation Army troops were rarely seen outside their main barracks in Hong Kong's Central district or other smaller facilities across the territory.
But, 20 years after the handover, the Chinese military garrison here is taking on a more active role, according to a recent article in a Communist Party journal, with the PLA conducting drills and war games in the territory.
The article comes amid speculation that Beijing may be sending its prized aircraft carrier to Hong Kong in a show of military might not seen since it made the territory a special administrative region, with its own set of laws, in 1997.
The carrier, with its complement of J-15 fighter jets and escorted by two destroyers and a frigate, left the eastern Chinese port of Qingdao on Sunday on a routine mission, China's state-run Xinhua news agency said Sunday.
"[The garrison] has been adapting to the new situation and task requirements and transformed from a symbolic presence to a show of force, from image building to combat capability development," according to the article, which appeared in the latest issue of Qiushi.
The article called the PLA's 6,000-troop garrison key to defending Hong Kong, and said the garrison was studying "potential safety risks" to the region of 7.3 million people.
The Qiushi article carried the bylines of Vice Adm. Yuan Yubai, the recently appointed commander of the PLA's Southern Theater Command, and Wei Liang, the political commissar of Southern Theater Command.
While saying their combat role would increase, the Qiushi article said the Hong Kong garrison still had an important political role to play.
"Hong Kong is a forefront of the east-west clashes of ideology and values," it read. "The soldiers face long-term grim challenges of ideology and debauchery."
Hong Kong-based troops need to "prevail in ideological combat ... and stay absolute loyal, pure and reliable," it said.

Reminder of China's 'power and strength'
Analysts agree that the move strengthens Beijing's hand in Hong Kong on two fronts.
"A well trained and equipped military force is better positioned to deal with threats to Beijing's control of the city than a poorly trained symbolic garrison unit," said Timothy R. Heath, a senior defense analyst at the RAND Corp think tank in Washington, DC.
"The professionalization of the PLA garrison force also serves a political purpose in instilling patriotism among Hong Kong residents and reminding them of China's power and strength," Heath said in an email to CNN.
It also is a message that Beijing doesn't find Hong Kong that special anymore, analysts say.
"The Chinese government is trying to turn Hong Kong into just another Chinese city," said Ely Ratner, senior fellow in China studies at the Council on Foreign Relations in Washington.

PLA's low profile gives way
In October, the PLA held an exercise in Hong Kong's New Territories simulating retaking parts of the region from an armed occupying force. It was the second straight year that war games had been put on in Hong Kong before a crowd of invited guests, according to the South China Morning Post.
Then in November, members of the Hong Kong garrison joined other forces from Southern Theater Command for joint drills with forces from Malaysia in that country. It was the first time China announced Hong Kong forces taking part in an overseas drill, according to a report in the state-sanctioned Global Times.

Earlier this year, Chinese state-run media outlets featured photos of PLA units, including helicopters and warships, conducting "routine patrols" of Hong Kong Harbor between Hong Kong Island and Kowloon.
Carrier visit would 'send message'
And, if media speculation around East Asia is correct, the PLA may be sending its biggest asset, the 1,000-foot-long aircraft carrier Liaoning, to Hong Kong shortly after the handover anniversary celebrations.
While Xinhua said it was going on a routine training mission, the Chinese-language Sing Tao Daily in Hong Kong, citing unidentified sources, said the Liaoning would call there on July 7, a visit that would coincide with the 80th anniversary of the Japanese invasion of China in the early days of World War II.
