China's commerce ministry says Beijing is prepared to fight the U.S. "at any cost" as a trade dispute between the world's two largest economies escalated with President Donald Trump ordering the U.S. trade representative to consider slapping an additional $100 billion in tariffs on Chinese goods.

The ministry said in a statement Friday that if Washington persisted in what Beijing describes as protectionism, China would "dedicate itself to the end and at any cost and will definitely fight back firmly."

Trump's surprise directive Thursday came a day after Beijing announced plans to tax $50 billion in American products, including soybeans and small aircraft, in response to a U.S. move this week to slap tariffs on $50 billion in Chinese imports.

President Donald Trump has instructed the U.S. trade representative to consider slapping $100 billion in additional tariffs on Chinese goods.

The move comes a day after China issued a $50 billion list of U.S. goods including soybeans and small aircraft for possible tariff hikes in an escalating and potentially damaging dispute.

The White House says Trump has instructed the Office of the United States Trade Representative to consider whether $100 billion of additional tariffs would be appropriate under section 301 and, if so, to identify which products they should apply to.

He's also instructed his secretary of agriculture "to implement a plan to protect our farmers and agricultural interests."

Trump argues China's trade practices have led to the closure of American factories and the loss of millions of American jobs.
