China will have to take countermeasures if the United States is bent on putting more tariffs on Chinese goods, the Chinese foreign ministry said on Friday.

China doesn't want a trade war, but it isn't afraid of fighting one, Hua Chunying, spokeswoman at the foreign ministry, said at a daily press briefing.

U.S. President Donald Trump on Thursday vowed to put additional 10% tariffs on $300 billion of Chinese imports from Sept. 1, sharply escalating a bruising trade war between the world's two largest economies and rocking financial markets. The additional duties will extend Trump's trade tariffs to nearly all of the Chinese goods that the United States imports and marks an end to a truce in a year-long trade row.
