If the U.S. goes through with an additional $100 billion in tariffs, China will not hesitate to fight back and is already prepared to, the Ministry of Commerce said.

“We will immediately fight back with a major response,” the representative said during a Chinese-language briefing with reporters Friday in Beijing. “We have no other choice.”

“We feel America is very arrogant. They have taken a wrong action. The result is that they will hurt themselves. If they release the list of $100 billion tariffs, China is prepared. And will not hesitate,” he added.

U.S. President Donald Trump said late Thursday he instructed the United States Trade Representative to consider $100 billion in additional tariffs against China. Stock index futures fell sharply after the news, with Dow futures off more than 200 points, on fears of retaliation by China.
