China issued a chilling warning after President Joe Biden promised military aid for Taiwan sending tensions in the region spiraling.

Despite the relatively modest $80million promised, Beijing has been infuriated by the use of the so-called Foreign Military Financing program.

The fund is typically reserved for sovereign, independent states - China sees Taiwan as a renegade province and vows to retake the democratically-run island.

The Global Times - a communist state-run newspaper largely seen as Beijing's mouthpiece - went on the offensive issuing a stark warning after the announcement.

"China's strong dissatisfaction and firm opposition are obvious, but China's response to the continuous provocations by the US on the Taiwan question will not be limited to mere statements," the paper wrote in an op-ed.

It added: "With the increasing number and intensity of its intervention methods, the brewing and imminent storm of lethal consequences for Taiwan cannot be ignored."

The US State Department said the transfer of funds would "be used to strengthen Taiwan's self-defense capabilities" while enhancing maritime awareness and capabilities.

In addition to the Global Times, top Chinese Foreign Ministry spokesperson Wang Wenbin slammed the move and reaffirmed Beijing's belief that Taiwan was an "inalienable" part of China.
