The Chinese military warned off a Philippines military aircraft with a vociferous message demanding the plane «immediately» leave the aerospace over the South China Sea.
Bejing has long locked horns with Manila over access to the common sea strip, with China advancing militarisation efforts in the area despite a case from the international tribunal in The Hague ruling it had no historic right to the South China Sea.
Video captured from a BBC crew on board a US Navy plane captured the stark warning from the Chinese military: «Philippine military aircraft, I’m warning you again.
«Leave immediately or you will bear responsibility for all the consequences.»
The BBC report also caught the Chinese military repeatedly calling on the US plane to leave the South China Sea, spurring a firm response from several branches of the US armed forces.
While the crew on board remained unfazed by the warning, reassuring the BBC it was a «routine occurrence» to hear the messages, the US military had forceful words with its Chinese counterparts.
Writing on the force’s verified Twitter account, the US Navy said: «We will sail, fly and operate wherever international law allows.»
The US Indo-Pacific command said the US would not be «warned off» during scheduled operations: «The United States will not be ‘warned off’ from lawful operation in international waters and airspace.»
Leave immediately or you will bear responsibility for all the consequences
China has continued to build a series of military outposts in the South China Sea despite complaints from the Philippines, Vietnam, Malaysia, Taiwan and Brunei who also claim rights over the area.
While Bejing has claimed the outposts have defensive purposed the United States has condemned China for the continued construction over concerns it would disrupt free movement in the South China Sea.
Beijing has said it is necessary for the Asian powerhouse to keep growing its military presence in the South China Sea in order to protect its sovereignty.
China also blames Washington and its allies for tensions in the region, claiming that the regular US Navy patrols and flyovers of the South China Sea are efforts for the US to provoke China and therefore the country is justified in increasing its military presence.
Chinese Foreign Ministry spokeswoman Hua Chunying said: «By playing up the so-called China’s militarisation in the South China Sea, certain people in the US are staging a farce of a thief crying ‘stop thief’.
«It is self-evident to a keener eye that who is militarising the South China Sea.»
The sea spans 3.6million square-kilometres and Beijing’s claims extend more than one thousand kilometres from its southernmost province, which is almost the entirety of the waters.
The United Nations has estimated that a third of global shipping passes through the waters.
The South China Sea is also believed to be rich in oil and natural gas reserves that have yet to be explored.
