“So several days later [after the aircraft carrier manoeuvres], we launched the DF-21 and DF-26, and the missiles hit a vessel sailing south of the Paracel Islands,” Wang said at a closed-door meeting in Zhejiang last month. The details of his speech were published for the first time on Wednesday.“Shortly after that, an American military attaché in Geneva complained [to us] and said it would lead to severe consequences if the missiles hit an American aircraft carrier. They see this as a show of force. But we are doing this because of their provocation,” Wang said.
BTW, Harry Harris almost triggered a conflict in 2016 over S.China Sea, prompting three fleets of PLAN to stage real live exercise in S.China Sea in preparation for it, together with the 2nd artillery. China is prepared to fight over S.China Sea, don't ever think China won't fight over Taiwan.
