Washington has already pledged to impose additional tariffs on Chinese products if Beijing retaliates while blaming China for supposedly conducting unfair trade practices and stealing intellectual property for years.
Top among American products hit by China's duties are agricultural exports, with soybeans, sorghum, oranges, pork, poultry and beef included in the US$34 billion in goods targeted for higher border taxes starting next month.
"We will immediately introduce taxation measures of the same scale and with the same intensity", the country's commerce ministry said.
China's Ministry of Commerce said the decision to impose tariffs meant "all previously agreed trade negotiation results are no longer valid".
And the China trade offensive is only one side of Trump's multi-front battle with all major USA economic partners.
The United States of America is now feeling the impact of retaliatory tariffs imposed by China with heavy import duties worth tens of billions of dollars on USA goods including lobsters, soybeans, electric cars and whiskey. Worse, he argued that the imported metals posed a threat to US national security - an insult to the longstanding American allies that they roundly rejected. It also added, "China is a powerful guardian and has enough ammunition to defend existing trade rules and fairness". They say those violate Chinese market-opening commitments under the World Trade Organization. "China opts for the first one and has made such a decision", Wang said before warning, "we hope the USA will make a wise choice and China on its part is prepared on all fronts".
United States officials have said Beijing has sought industrial dominance in emerging technologies through the theft of American know-how through forced technology transfers, hacking and other forms industrial espionage.
"China is our real trade enemy, and their theft of intellectual property and their refusal to let our companies compete fairly threatens millions of future American jobs", Schumer said in a statement.
At least initially, though, the new tariffs will not cover the full $50 billion in trade that the White House had threatened in March.
"The only question is how much do you want to pay", said Brandon Fried, executive director of the Airforwarders Association, "and which is better - paying that or paying the increased tariff?"
USA officials say Beijing has sought industrial dominance in the emerging technologies through the theft of American know-how through forced technology transfers, hacking and other forms industrial espionage.
"There will be an impact on growth, in China, the U.S. and elsewhere", said Louis Kuijs, head of Asia Economics at Oxford Economics, in a research note. -China Business Council says she suspects Beijing will wait to see whether the United States actually puts the USA tariffs into effect July 6 before it starts taxing US goods.
"China has noticed the U.S. statement which said Washington would continue to impose additional tariffs if China takes retaliatory measures".
It can take several weeks for ship-borne cargo from China to reach the United States - too late to beat the July 6 deadline.
But Beijing's Commerce Ministry retorted: "The Chinese side doesn't want to fight a trade war, but facing the shortsightedness of the US side, China has to fight back strongly".
It comes in the aftermath of Trump's nuclear summit with North Korean leader Kim Jong Un (kim jawng oon) and his push for China to maintain economic pressure on the North.
Earlier, trade expert Stephen Jacobi told NBR that while New Zealand has few exports in the areas targetted by Mr Trump for tariffs (our steel and aluminium exports to the United States a year ago totalled $60m), there could be a substantial indirect cost.
