(CNN)China says it has landed long-range bombers for the first time on an island in the South China Sea, the latest in a series of maneuvers putting Beijing at odds with its neighbors and Washington over China's growing military presence around disputed islands.
China tests bombers on South China Sea island
The People's Liberation Army Air Force (PLAAF) announced on Friday it successfully organized the takeoff and landing of several bombers, including the nuclear-capable H-6K, on an unspecified island. The PLA claimed the mission was a part of China's aim to achieve a broader regional reach, quicker mobilization, and greater strike capabilities.
"The islands in the South China Sea are China's territory," Chinese Foreign Ministry spokesperson Lu Kang said in a statement Monday. "The relevant military activities are normal trainings and other parties shouldn't over-interpret them.
"As for the so-called militarization mentioned by the US, what we do is fundamentally different from the US sending its military aircraft and warships from thousands of miles away to this region and posing a threat to other countries."
A military expert, Wang Mingliang, was quoted in the statement as saying the training will hone the Chinese air force's war-preparation skills and its ability to respond to various security threats in the region, where China claims large swathes of territory.
The South China Sea is one of the most contested regions in the world, with overlapping territorial claims by multiple countries including the Philippines, Malaysia, Brunei and Vietnam.
Over the past few years China has been rapidly transforming various reefs and inlets into artificial islands to install military infrastructure. Some experts have called them "unsinkable aircraft carriers."
A Twitter post by the Chinese Communist Party's official newspaper, People's Daily, shows video of a long-range bomber taking off, flying, and landing on one of the islands. Analysts at the Center for Strategic and International Studies' Asia Maritime Transparency Initiative (AMTI) said it was thought to be Woody Island, China's largest base in the Paracel Islands and the only one with an airstrip long enough to allow bomber landings.
The move is a strategic accomplishment for China to further reinforce its military and political power in the disputed waters.
The H-6K is a considerable upgrade from the fighter jets believed to have previously landed on the islands. China's top-of-the-line bomber is capable of reaching a nearly 1,900-nautical-mile (3,500-kilometer) radius. Flying the twin-engine bombers out of Woody Island would mean the entirety of Southeast Asia is within combat flight range, experts say.
"The H-6K is significant because it provides Beijing with longer-ranging bomber capabilities that can drop precision-guided munitions on both ground and sea targets," Rand Corp. defense analyst Derek Grossman said in an email to CNN.
"Moreover, landing the bomber on Woody Island provides an opportunity for Chinese pilots to train under realistic circumstances," Grossman said.
While Woody Island sits in the central South China Sea, the AMTI says satellite imagery indicates China has built near identical operational runways at its three main outposts in the Spratly Islands known as Mischief, Subi and Fiery Cross Reef, which sit near the southern extent of the sea.
Should Beijing soon pursue deployments from the Spratlys, as predicted, they could potentially reach northern Australia and US defense facilities on Guam, according to the AMTI.
This comes just weeks after reports that the Chinese military installed radar jamming equipment and deployed their first missiles in their Spratly holdings.
And in mid-April, China conducted its largest-ever naval parade in the South China Sea, which came after the aircraft carrier Liaoning led a flotilla of 48 naval vessels plus 76 fighter jets in two-days of combat drills.
In a 2015 visit to Washington, Chinese President Xi Jinping assured then-US President Barack Obama, "China does not intend to pursue militarization." But US military officials say China's recent military activities belie that promise.
Pentagon spokesman Lt. Col. Christopher Logan told CNN, "the United States remains committed to a free and open Indo-Pacific," he adds, "China's continued militarization of disputed features in the South China Sea only serves to raise tensions and destabilize the region."
