BEIJING: Days after China passed a new law that for the first time permits its military to venture overseas on counter-terror operations, its marines began exercises in the western deserts of Xinjiang, more than 2,000 kilometres from the nearest ocean.

The continuing drills are an indication, analysts say, that the marines, who have traditionally trained for amphibious assault missions, are being honed into an elite force capable of deploying on land far from mainland China.

China's limited means to respond to threats abroad were highlighted by two incidents in November: when the militant Islamic State (IS) group executed a Chinese hostage, and the killing of three executives by militants who attacked a hotel in Mali.

China's new counter-terrorism law, passed in late December, is aimed at protecting its expanding global commercial and diplomatic interests.

But China's military commanders are also trying to create a military in the likeness of the world's most dominant power projection force, analysts say.

"They study what the Americans have done very carefully and it's the mirror image effect," said Leszek Buszynski, a visiting fellow at the Australian National University's Strategic and Defence Studies Centre.

The cold weather training will improve the marines' ability to conduct "long-distance mobilisation in unfamiliar regions", the deputy chief of staff of the Navy's South Sea fleet Li Xiaoyan said in a Ministry of Defence statement earlier this month.

During the drills, the marines will travel 5,900 kilometres via air, truck and rail beginning in the southern province of Guangdong, the longest range manoeuvres ever conducted by the force, state media said.

Expeditionary force

The exercises are the latest in recent years that show the efforts China is making to boost its expeditionary force capabilities.

In 2014, the marines conducted their first training in the grasslands of the northern landlocked Inner Mongolia region.

At the time, the exercise was seen as unusual for the south China-based force more proficient in beach landings.

Since those drills, the roughly 15,000-strong marine corps, which operates under the People's Liberation Army (PLA) Navy's South Sea fleet, appears to be settling into a new niche.

"They never really had a major strategic role, as force projection wasn't something the PLA was willing, or able, to think about even ten years ago," said Gary Li, an independent security analyst in Beijing.

With amphibious divisions in the PLA Army also capable of extending China's reach into the South China Sea and Taiwan, Li said the marines are a good fit for a budding Chinese expeditionary force.

"The main advantage of playing around with the marines is that they have a higher concentration of specialists, act well as light infantry, have good esprit de corps, and are nimble enough to be deployed over long distances if needed," he said.

Rising global profile

Along with President Xi Jinping's vows to build a more modern military, the global profile of China's armed forces is on the rise.

Already, the South Sea fleet, which is based on the mainland coast near the island of Hainan, has been used on operations far from the South China Sea.

The fleet's vessels have ventured to the Middle East and Mediterranean after deployments on international anti-piracy patrols around the Horn of Africa.

Chinese officials announced in November they were in talks with Djibouti to build permanent "support facilities" to further boost Chinese naval operations, in what would be China's first such off-shore military base.

The African port, sitting on the edge of the Red and Arabian seas, is home to several foreign military bases, including United States (US), French and Japanese naval facilities.

China is also expanding its peacekeeping role, with Xi pledging in September to contribute 8,000 troops for a United Nations (UN) stand-by force that could provide logistical and operational experience the PLA would need to operate farther abroad.

While China has been getting more involved diplomatically in trouble spots like the Middle East, it is adamant that it does not interfere in the affairs of other countries, and is the only permanent member of the UN Security Council which has not taken military action in Syria.

The Defence Ministry said in a fax that the drills were part of "annual planned" exercises.

For now, China's marines are advancing only through the snow fields of Xinjiang, as depicted in state media photographs, still wearing their speckled blue fatigues designed for operations at sea. But that could shift in time.

"China's global security posture is becoming more active," said Zhang Baohui, a mainland security expert at Hong Kong's Lingnan University. "And this seems to fit that policy."
