China’s enemies will “have their heads cracked and bleeding” in any future conflict, the communist regime’s chief vowed during a speech marking the centenary of the Chinese Communist Party.

“We will never allow any foreign force to bully, oppress, or subjugate us,” Chinese President Xi Jinping said, according to the English text of his speech. “Anyone who would attempt to do so will find themselves on a collision course with a great wall of steel forged by over 1.4 billion Chinese people.”
