WATCH: Pentagon holds news briefing as new information revealed on Chinese balloon

Pentagon press secretary Pat Ryder holds a news briefing on Friday as new information is revealed on a Chinese balloon the United States said was conducting surveillance.

The China balloon shot down by the U.S. was equipped to detect and collect intelligence signals as part of a huge, military-linked aerial surveillance program that targeted more than 40 countries, the Biden administration declared Thursday, citing imagery from American U-2 spy planes.

A fleet of balloons operates under the direction of the People’s Liberation Army and is used specifically for spying, outfitted with high-tech equipment designed to gather sensitive information from targets across the globe, the U.S. said. Similar balloons have sailed over five continents, according to the administration.

A statement from a senior State Department official offered the most detail to date linking China’s military to the balloon that was shot down by the U.S. last weekend over the Atlantic Ocean. The public details outlining the program’s scope and capabilities were meant to refute China’s persistent denials that the balloon was used for spying, including a claim Thursday that U.S. accusations about the balloon amount to “information warfare.”

President Joe Biden defended the U.S. action.

And, asked in an interview with Spanish language Telemundo Noticias whether the balloon episode represented a major security breach, he said no.

“Look, the total amount of intelligence gathering that’s going on by every country around the world is overwhelming,” he said. “Anyway, it’s not a major breach. I mean, look … it’s a violation of international law. It’s our airspace. And once it comes into our space, we can do what we want with it.”

On Capitol Hill, the House voted unanimously to condemn China for a “brazen violation” of U.S. sovereignty and efforts to “deceive the international community through false claims about its intelligence collection campaigns.” Republicans have criticized Biden for not acting sooner to down the balloon, but both parties’ lawmakers came together on the vote, 419-0.

In Beijing, before the U.S. offered its new information, Chinese Foreign Ministry spokesperson Mao Ning repeated her nation’s insistence that the large unmanned balloon was a civilian meteorological airship that had blown off course and that the U.S. had “overreacted” by shooting it down.

“It is irresponsible,” Mao said. The latest accusations, she said, “may be part of the U.S. side’s information warfare against China.”

Underscoring the tensions, China’s defense minister refused to take a phone call from Defense Secretary Lloyd Austin to discuss the balloon issue on Saturday, the Pentagon said. Secretary of State Antony Blinken canceled a planned weekend trip to Beijing.

The U.S. flatly contradicted China’s version of events, saying that imagery of the balloon collected by American U-2 spy planes as it crossed the country showed that it was “capable of conducting signals intelligence collection” with multiple antennas and other equipment designed to upload sensitive information and solar panels to power them.
