"In order to safeguard its legitimate rights and interests and the global free trade order, China has no choice but to take countermeasures in lockstep", the commerce ministry said in the statement, which did not mention a previous threat to add tariffs on US$60 billion in U.S. imports if Washington imposed this new wave of levies. Beijing is still ready to negotiate an end to the trade tensions, it said.
"China has had many opportunities to fully address our concerns", Trump said.
Once the new round of tariffs takes effect on September 24, punitive duties will be in place on roughly half of the products the USA buys from China - its largest source of imported merchandise.
Taken with the $50 billion in tariffs already in place, this means roughly half of everything Americans buy from China - their largest source for imports - is now subject to punitive import duties.
The lower Chinese figure highlights Beijing's inability to match the USA dollar-for-dollar in a tariffs war.
On a panel at meetings of the World Economic Forum (WEF) in Tianjin, Fang Xinghai, vice chairperson of China's Securities Regulatory Commission, said China won't be pressured by Trump's trade tactics and talked up the economy's strength.
Mr Trump signed the first order applying tariffs on £38bn ($50bn) on Chinese good on March 22.
The latest escalation of the US-China trade clash had all but dismantled the platform for the proposed negotiations before they could even begin. "But, so far, China has been unwilling to change its practices", including theft and force transfer of technology.
Officials have said they want to shield consumer goods from the taxes as much as possible.
Financial journalists have speculated that China may seek to exact pain on the United States through means other than tariffs, such as by harassing US companies doing business in China, disrupting supply chains for American companies that originate in China, or causing mischief with, for instance, attempts by the United States to negotiate with North Korea over its nuclear arsenal.
US President Donald Trump's announcement of fresh tariffs on Chinese goods has shook Wall Street.
A weaker U.S. dollar has boosted gold prices while the price of most base metals slipped on the back of concerns that demand for metals will weaken as a result of the trade dispute.
"Now is the time for talks-not just tariffs-and manufacturers have laid out a blueprint to reset the US-China commercial relationship that will result in ending China's unfair and anti-competitive behavior", Jay Timmons, NAM's president and CEO, said.
The US had already imposed 25% tariffs on $50bn (£38bn) in Chinese imports.
"We stand ready to negotiate with China anytime, if they are willing to engage in serious talks", Kudlow said at the Economic Club of NY.
In remarks from the Roosevelt Room, he said he was confident an agreement could eventually be reached with China, but stressed such an accord must do right by American workers. "We urge the administration to reconsider its misguided approach of increasing tariffs, as they are directly paid for by American companies and consumers".
They were among 300 tariff lines scrubbed from the preliminary list released in July, one of the officials said.
Trump added. Trump won the 2016 presidential contest with strong support from those farmers and blue-collar voters.
China will impose a 10 per cent tariff on United States products it previously designated for a rate of 20 and 25 per cent, and 5 per cent tariffs on goods previously under the 5 and 10 per cent rates.
While Trump says the tariffs will mean "a lot of money coming in to the coffers of the United States" they are really a tax on USA companies and consumers.
