The People's Republic of China lobbied criticisms at the United States on Monday over the nation's recent actions to protect its airspace.

Chinese Ministry of Foreign Affairs spokesperson Wang Wenbin spoke to reporters Monday about the multiple aircraft shot down over the U.S. since the destruction of an unmanned Chinese surveillance balloon earlier this month.

“We have made it clear time and again that the entry of the Chinese civilian unmanned airship into U.S. airspace was a purely unintended, unexpected and isolated event caused by force majeure,” said Wang.

However, Wang could not provide any information on whether any of the recently downed aircraft belonged to China, saying, “As to the ‘unidentified objects’ you asked about, I do not have anything on that.”
