China on Thursday intensified its rhetoric directed towards Taiwan and said its independence would result in war.
Reuters reported that Chinese Defense Ministry spokesman Wu Qian was holding his monthly press conference when the subject turned to regional tensions.
Taipei accused Beijing of flying a dozen military jets in its airspace on Sunday in an act of intimidation. U.S. observers said China was intent on testing President Joe Biden, who had been sworn in just days before.
Wu said the "military activities" in the Taiwan Straits "are necessary actions to address the current security situation" there and then he warned, "Those who play with fire will burn themselves, and ‘Taiwan independence’ means war."
UN AMBASSADOR CRAFT CALLS FOR REFORM OF HUMAN RIGHTS COUNCIL, AS BIDEN LIKELY TO REJOIN
Taiwan and China separated amid civil war in 1949 and China says it is determined to bring the island under its control by force if necessary.

HALEY SAYS BIDEN REJOINING UN HUMAN RIGHTS COUNCIL WOULD 'FLY IN THE FACE' OF RIGHTS PUSH
Secretary of State Antony Blinken said in a confirmation hearing Tuesday there is "no doubt" China poses the greatest threat of any nation to the U.S. and the Trump administration was right to take a tougher stance against the Asian power.
"President Trump was right in taking a tougher approach to China," said Blinken, who served as then-Vice President Biden’s national security advisor before being elevated to deputy secretary of state under Barack Obama. "Not the way he went about it in a number of ways, but the basic principle was right."
