"We urge the United States to correct its attitude and not to try to blackmail China because it will never work", said Geng at a news conference.
As for China's response, there are two angles: what it says, what it does and what it could do. "We advise the United States to be level-headed and avoid simply acting on impulse, otherwise it will ultimately hurt itself".
China's vice-trade minister Wang Shouwen said last month in Geneva that "for any talks to be successful, no party should point a gun at the other party".
Investors fear an escalating trade war between Washington and Beijing could hit global economic growth, and prominent U.S. business groups, while tired of what they see as China's mercantilist trade practices, have condemned Mr Trump's aggressive tariffs.
"Given the scope of the products covered, about half of all imports from China are facing tariffs, including consumer goods", Ennis said.
"On June 18, the President directed me to identify $200 billion worth of Chinese goods for additional tariffs at a rate of 10 percent, in response to China's decision to cause further harm to USA workers, farmers, and businesses by imposing retaliatory duties on US goods". He said the president had asked him to consider increasing the proposed tariffs.
In his statement, Lighthizer said the option for higher tariffs on the Chinese goods was created to pressure Beijing into economic reforms, such as curtailing the theft of U.S. intellectual property by Chinese firms.
"It's important countries refrain from devaluing currencies for competitive purposes", a senior administration official said, and although he didn't accuse China of acting in that fashion, the implication was clear.
The two sides held three rounds of formal talks, beginning with a delegation to Beijing led by Mnuchin in May.
Also, if Beijing gave any indication it was prepared to back down, Trump would exploit it to push for an even better deal for the USA, he said.
Christopher Matthews is a writer who splits his time between New York City and Accra, Ghana, with an interest in the intersection of markets, the economy, and public policy. "Nor did it make concerted efforts with China".
The U.S. imposed 25 percent tariffs on $34 billion of Chinese products earlier this month, with plans to add another $16 billion of imports on Tuesday. Is the USA trying to put tariffs on its own companies?
A further escalation of the dispute would be a threat to world trade as a whole.Since a high in January, the value of mainland stocks has fallen by about US$1.6 trillion - roughly the size of Canada's gross domestic product - jeopardising China's position as the largest capital market in Asia.
