The US officials say that Joe Biden's administration's improvements to strengthen defenses against Chinese espionage helped identify a spy balloon that entered US airspace.
They also uncovered multiple instances of Chinese surveillance balloons traversing American airspace during the Trump administration.
The previous four violations of US sovereignty, including one during Biden's presidency, did not go on for as long as the recent incursion that ended when the balloon was shot down.
Some Trump administration officials have said they were unaware of the incidents.
US officials have expressed concerns after a Chinese spy balloon was detected within US airspace.
After conducting an investigation, it was traced back to Canada before authorities were able to shoot it down over the south-east coast of America.
Representatives of Biden's administration stated that improvements to strengthen defenses against Chinese espionage led to the detection and discovery of similar activities during the Trump administration.
Chinese surveillance balloons appeared to have traversed American airspace on various occasions, some of which went unidentified during the Trump administration.
Before Monday, US officials had stated that there had been multiple instances of balloons crossing American airspace, but none had been detected for this long.
In response, the Trump administration and Republicans have rejected allegations of such claims, while also trying to place blame on Presidents Obama and Biden.
