Trump's top economic adviser, Larry Kudlow told Fox News on Wednesday that the USA government had received information that "the top of the Chinese government wished to pursue talks" prompting Mnuchin to send an invitation.
The survey of more than 430 AmCham China and AmCham Shanghai member companies, including 36 in automotive and transportation, was conducted between August 29 and September 5.
The decision comes one week after Donald Trump said he would be adding tariffs on United States dollars 200 billion in Chinese goods.
The two governments have already imposed 25 per cent tariffs on $US50 billion of each other's goods.
Some of them have criticized Trump's tactics but many echo US complaints about Chinese market barriers and industrial strategy.
Trump has already imposed 25% tariffs on steel imports and 10% on aluminum, as well as 25% on $50 billion in goods from China.
Beijing has issued a list of another US$60 billion of United States products for retaliation if Trump's next tariff hike goes ahead.
U.S. President Donald Trump said last week that in addition to preparing tariffs on the further $200 billion worth of goods, he had tariffs on an additional $267 billion worth of goods ready "on short notice if I want".
About it reports Reuters, citing a senior official in the White house, reports the online edition of the Chronicle.info with reference to the Correspondent.
CNN quoted a White House spokeswoman, Lindsay Walters, saying, "The President has been clear that he and his administration will continue to take action to address China's unfair trade practices". United States officials also worry they might erode U.S. industrial leadership. "That at the recent hearing on the US's additional tariffs on $200 billion worth of Chinese imports, the majority of the representatives believed that the additional tariffs will hurt U.S. enterprises or even destroy those affected industries".
The move came as both countries implemented tariffs this summer on $50 billion worth of goods from the other. Mr Mnuchin has led a recent overture to the Chinese to restart trade talks.
China has threatened retaliation, which could include action against USA companies operating there. Trump ordered his advisers to come up with a list of $200 billion of other Chinese products to penalize, a package that includes many consumer products. But the timing for activating the additional tariffs was unclear at that time.
The U.S. Trade Representative's office has said it was working to revise the list based on issues raised in public hearings and written submissions. Still, the additional tariffs could complicate trade talks with China expected later this month.
