The notice attributed the change to new US-Chinese engagement "with the goal of obtaining the elimination of the acts, policies, and practices covered in the investigation" following a December 1 meeting between President Donald Trump and Chinese President Xi Jinping in Buenos Aires.
The meeting is among the evidence that the world's two largest economies are making progress in cooling trade tensions. Beijing recently announced a third round of tariff cuts, lowering the duties on more than 700 goods starting January first.
Chinese and USA officials have been in constant contact since the meeting in Argentina, but China isn't exactly clear on the specifics of what the US wants, according to two people in Beijing with knowledge of the talks.
Trump also agreed to leave the tariffs on $200 billion worth of Chinese products at 10 percent, and not raise them to 25 percent on January 1 as he had threatened. It's also slashed import tariffs on more than 700 products and began buying USA crude oil, liquefied natural gas and soybeans again.

Consultations through "intensive" telephone calls will continue in the meantime, Gao Feng, spokesman at the Commerce Ministry, told reporters, adding that talks have been steadily moving forward despite the Christmas break in the United States.
"The Chinese and U.S. economic and trade teams have always maintained close communication", said commerce ministry spokesman Gao Feng at a regular briefing.
But Trump and other members of his trade team, including National Economic Council Director Larry Kudlow, have said they could further delay an escalation in tariffs if the two sides made sufficient progress.
