Chinese spy balloon collects intel on US military sites despite US efforts.

A Chinese spy balloon that flew over the United States in February was able to gather intelligence from several US military sites and transmit it back to Beijing in real time, according to NBC News. The balloon, controlled by Beijing, was shot down by the US military on February 4. The incident further strained relations between the US and China, prompting US Secretary of State Antony Blinken to postpone a planned visit to Beijing. The Chinese government denies that the balloon was a spy vessel.
