On Tuesday, the Wall Street Journal reported that Beijing was planning to reduce import tariffs on US-made cars and purchase more American soybeans and other crops.
"That will help a lot," Ross told CNBC when asked about China's reported plans.
"They export about 40 percent of their vehicles to China, so that's a very direct help to us and probably will be helpful in the talks we are having with the German auto manufacturers," Ross said.
US media reported that China plans to roll back tariffs on US auto imports from 40 percent to 15 percent. The tariffs were raised in August amid escalating trade war between the two countries.
Chinese Vice Premier Liu He told US Treasury Secretary Steven Mnuchin and US Trade Representative Robert Lighthizer of the decision in a call late Monday, the newspaper reported, citing a person familiar with the negotiations.
Trump agreed to suspend plans to raise tariffs on $200 billion worth of Chinese products from 10 percent to 25 percent in order to pave the way for trade talks with Beijing, but warned that if the negotiations do not succeed within three months, the tariffs will be hiked as planned.
China and the United States have been engaged in a trade war after Trump announced in June that $50 billion worth of Chinese goods would be subject to 25 percent tariffs in a bid to fix the US-Chinese trade deficit. Since then, the two countries have exchanged several rounds of trade duties on hundreds of billions of dollars worth of goods.
