China will return an underwater U.S. drone seized by a naval vessel this week in the South China Sea, both countries said on Saturday, but Beijing complained that Washington had been "hyping up" the incident.
The drone, known as an unmanned underwater vehicle (UUV), was taken on Thursday, the first seizure of its kind in recent memory. The Pentagon went public with its complaint after the action and said on Saturday it had secured a deal to get the drone back.
"Through direct engagement with Chinese authorities, we have secured an understanding that the Chinese will return the UUV to the United States," Pentagon spokesman Peter Cook said in a statement.
The incident drew criticism from U.S. President-elect Donald Trump, who has vowed to take a more aggressive approach in dealing with Beijing.
Trump, a Republican who takes office on January 20, waded into the dispute on Twitter on Saturday.
"China steals United States Navy research drone in international waters - rips it out of water and takes it to China in unprecedented act," Trump said in a tweet early on Saturday from his seaside resort club Mar-a-Lago in Palm Beach, Florida, where he plans to spend the holidays.
Hours later, while riding in a motorcade back to his resort, Trump tweeted his second jab. "We should tell China that we don't want the drone they stole back - let them keep it!" he said.
Trump has previously threatened to declare China a currency manipulator and force changes in U.S.-Chinese trade policy, which he says has led to the greatest theft of American jobs in history.
The drone, which the Pentagon said was operating lawfully and was clearly marked as U.S. property, was collecting data about the salinity, temperature and clarity of the water about 50 nautical miles northwest of Subic Bay, off the Philippines.
It was seized on Thursday just as the USNS Bowditch was about to retrieve it, U.S. officials said. CNN reports that the USNS Bowditch had actually stopped in the water to pick up two underwater drones, and at that moment, a Chinese naval ship that had been shadowing the Bowditch put a small boat into the water and retrieved one of the drones. U.S. oceanographic research vessels are often followed due to concerns they are spying.
On Sunday, Trump aide Reince Priebus defended the comments on the drone, saying he does not believe Trump's comments were provocative and that "80 percent" of Americans agree it was inappropriate for China to have seized the drone in the first place.
Republican Senator John McCain, chairman of the Senate Armed Services Committee, told CNN's "State of the Union" that the Chinese would be able to retrieve some "pretty valuable" technical information from the drone through a process known as reverse-engineering.
McCain said the Chinese seizure of the drone was a "gross violation" of international law. McCain, a critic of Democratic President Barack Obama's foreign policy, said the United States was not projecting enough strength in the world and said China's move reflected that.
"Everybody is taking advantage of it, and hopefully that will change soon," McCain said.
China’s Defense Ministry said a Chinese naval vessel discovered a piece of "unidentified equipment," and checked it to prevent any navigational safety issues before discovering it was a U.S. drone.
"China decided to return it to the U.S. side in an appropriate manner, and China and the U.S. have all along been in communication about it," the ministry said on its website.
"During this process, the U.S. side's unilateral and open hyping up is inappropriate, and is not beneficial to the smooth resolution of this issue. We express regret at this," it added.
The drone incident has raised fresh concerns about China's increased military presence and aggressive posture in the disputed South China Sea, including its militarization of maritime outposts.
New satellite imagery shows China has installed weapons, including anti-aircraft and anti-missile systems, on all seven artificial islands it has built in the South China Sea, a U.S. research group said this week.
Without directly saying whether the drone was operating in waters Beijing considers its own, China's Defense Ministry said U.S. ships and aircraft have for a long period been carrying out surveillance and surveys in "the presence" of Chinese waters.
"China is resolutely opposed to this and demands the U.S. stops this kind of activity," it said.
China will remain on alert for these sorts of activities and take necessary steps to deal with them, the ministry said without elaborating.
The Global Times, published by the ruling Communist Party's official People's Daily, earlier cited an unidentified Chinese source as saying they believed the issue would be resolved smoothly.
Trump has previously complained about the South China Sea build-up. He has threatened to declare China a currency manipulator and force changes in U.S.-Chinese trade policy, which he says has led to the greatest theft of American jobs in history.
Trump has also raised questions about whether Washington would stick to its nearly four-decades-old policy of recognizing that Taiwan is part of "one China."
He irked Beijing by taking a congratulatory phone call from President Tsai Ing-wen of Taiwan after his November 8 election victory. China lodged a diplomatic protest.
The 10-minute telephone call was the first of its kind since U.S. President Jimmy Carter switched diplomatic recognition from Taiwan to China in 1979, acknowledging Taiwan as part of "one China."
President Barack Obama said on Friday it was fine for Trump to review Washington's policy toward Taiwan, but he cautioned that a shift could lead to significant consequences in the U.S. relationship with Beijing.
After China said it would return the drone, Jason Miller, a spokesman for Trump, tweeted a link to a news story, saying: "@realdonaldtrump gets it done."
There was, however, no evidence that Trump had played any role. U.S. officials said the negotiations took place in Beijing during the overnight hours in the United States.
Miller did not respond to requests for comment.
