China warned Tuesday that the testing of a medium-range cruise missile by the US would start a new "arms race", after a launch off the coast of California.
"This measure from the US will trigger a new round of an arms race, leading to an escalation of military confrontation, which will have a serious negative impact on the international and regional security situation," said Chinese foreign ministry spokesman Geng Shuang.
Geng said that the US should "let go of its Cold War mentality" and "do more things that are conducive to... international and regional peace and tranquillity."
