The office of US Trade Representative Robert Lighthizer has released a list of Chinese products, running to nearly 200 pages, that will potentially be hit with a 10 per cent import tax as early as September. The office will hear public comments on the plan and will reach a decision after August 31, according to a senior administration official who briefed reporters on condition of anonymity.
"Consumers, businesses and the American jobs dependent on trade are left in the crosshairs of an escalating global trade war".
The tariff list could be released as soon as Tuesday, and likely this week, the report said.
The Trump administration on July 6 imposed 25 per cent duties on US$34 billion in Chinese imports, the first time the president has implemented tariffs directly on Beijing after threatening to do so for months.
Companies are "scrambling to readjust supply chains" so goods bound for the United States don't pass through China, Harborn said at a news conference.
Chinese officials are expected to retaliate in other ways, hitting USA firms in China with unplanned inspections, delays in approving financial transactions and other administrative headaches.
The American president told reporters that tariffs on an additional $16 billion in Chinese goods are set to take effect in two weeks.
"For over a year, the Trump Administration has patiently urged China to stop its unfair practices, open its market, and engage in true market competition", he said in a statement.
America's trade war with China is back on.
The move comes just days after the USA and China imposed tit-for-tat tariffs of $34bn on the other countries' goods.
The new duties are "a reckless strategy that will boomerang back to harm USA families and workers", said David French, the National Retail Federation's senior vice president for government relations. But Mr Trump hasn't backed down, arguing that China's unfair trading practices are hurting American workers.
But China only bought about $135 billion in USA goods previous year, meaning it will run out of American products to tax before it matches Trump's latest move.
The U.S. Chamber of Commerce, which has supported Mr Trump's tax cuts and efforts to reduce regulation of businesses, also criticised the administration's move.
