"The actions of the U.S. military seriously violated China's sovereignty and security," said Tian Junli, spokesman for the Southern Theatre Command of the People's Liberation Army.In a statement, the U.S. Navy said the Chinese statement was "false", calling it "the latest in a long string of PRC actions to misrepresent lawful U.S. maritime operations"."USS Chancellorsville (CG 62) conducted this FONOP in accordance with international law and then continued on to conduct normal operations in waters where high seas freedoms apply," the statement said, referring to a "freedom of navigation operation" by its military acronym.U.S. warships have passed through the South China Sea with increasing frequency in recent years in an effort to show the Chinese claims are not valid.Earlier, China's military said the U.S. cruiser's latest passage showed that the United States was a "security risk maker" in the South China Sea and "is another iron-clad proof of its hegemony in the navigation and militarization of the South China Sea"."
