U.S. stocks plunged again Friday over increasing concerns about a trade war between the United States and China.
The Dow Jones industrial average lost 572 points by the close, shedding 2.3 percent. The Standard & Poor's 500 dropped nearly 2.2 percent, while the NASDAQ fell nearly 2.3 percent at the end of trading.
Earlier Friday, President Donald Trump continued to protest China's trade practices after threatening China on Thursday with increased tariffs on $100 billion worth of additional goods.
In a twitter post Friday, Trump said, "China, which is a great economic power, is considered a Developing Nation within the World Trade Organization. They therefore get tremendous perks and advantages, especially over the U.S. Does anybody think this is fair. We were badly represented. The WTO is unfair to U.S."
China's commerce ministry said in a statement Friday that if Washington persisted in what Beijing described as protectionism, China would "dedicate itself to the end and at any cost and will definitely fight back firmly."
Since the start of this week, the United States and China have been engaging in a tit-for-tat trade spat.
Early in the week, the United States proposed tariffs on $50 billion worth of Chinese goods. China then said it would impose tariff hikes on $50 billion worth of U.S. goods, including soybeans and small aircraft. On Thursday, Trump announced he had instructed the U.S. trade representative to consider whether tariffs on another $100 billion worth of Chinese goods would be appropriate.
'China created this problem'
The White House blamed China on Friday for trade practices it said were illegal and unfair.
"China created this problem, and the president is trying to put pressure on them to fix this, and take back some of the terrible actions that they've had in the last several decades," said White House press secretary Sarah Huckabee Sanders during the daily briefing Friday.
Despite Trump's threats for more sanctions, he has insisted the U.S. is not engaged in a trade dispute with the Asian nation.
U.S. stocks also were affected this past Monday by Trump's new verbal attack on giant online retailer Amazon.
Since Trump started his criticism of Amazon, the company has lost more than $37 billion in market value.
