China called planned U.S. tariffs on an additional $300 billion in Chinese goods a violation of accords reached by Presidents Donald Trump and Xi Jinping, signaling an American move earlier this week to delay some of those levies was not enough to stave off retaliation.

The new 10% tariffs have taken the U.S. and China off the track of resolving their dispute through negotiation, the State Council Tariff Committee, which has overseen tit-for-tat retaliation, said in a short statement on Thursday. China “has no choice but to take necessary measures to retaliate,” it said, without specifying what the nation would do.
