"The more Trump is irritating allies and asking Chinese to buy stuff, the better off they are, because he's not sitting there and attacking the hard issues", the person said.
The two sides issued a joint statement in Washington last month, vowing to strengthen economic and trade cooperation between the two countries.
Private sector analysts say while Beijing is willing to compromise on its trade surplus, it will resist changes that might threaten plans to transform China into a global technology competitor.
"All economic and trade outcomes of the talks will not take effect if the U.S. side imposes any trade sanctions including raising tariffs", the statement said.
Before Ross arrived with his team for the two-day talks, the U.S. and China had threatened tit-for-tat tariffs on goods worth up to $150 billion each.
The US and China have threatened each other with $US150 billion in tariffs.
China has warned that all trade talks between Beijing and Washington will be void if the U.S. sets up trade sanctions. While the team may be inching toward technical agreement in that direction, the talks are overshadowed by the unpredictability of USA policy in the wake of recent reversals that have seen tariffs placed on metals imports by allies. China's willingness to buy more American products and allow USA investments with IPR protections raised hopes of an agreement, which led to current round of talks in Beijing.
Mr Ross and Mr Liu held a working dinner on Saturday ahead of their talks. But the United States Commerce Secretary appeared to be the only one in a positive mood.

Treasury Secretary Steven Mnuchin said Saturday the USA wants to see "structural changes" in the Chinese economy.
"Our meetings so far have been friendly and frank, and covered some useful topics about specific export items", Ross told the media after dining with Liu on Saturday evening.
The world's two largest economies have been at loggerheads over trade and industrial practices for months with the talks under way in the Chinese capital the third formal round of negotiations.
The previous round of talks in Washington saw China pledging "significant increase" in its purchases of United States agricultural goods. "Our set pace will not change", the statement said.
"But I also fundamentally believe that if there are structural changes that allow our companies to compete fairly, by definition, that will deal with the trade deficit alone".
The two governments released no schedule for the talks, but China said earlier Ross was due to be in Beijing through to Monday. China slammed the "flip-flop", vowing to hit back should the USA tariff threat materialize.
China is maneuvering to take advantage of rebukes from USA allies following the Trump administration's decision to slap tariffs on steel and aluminum imported from Canada, Mexico, and European Union.
China too threatened a tit-for-tat retaliation but blinked in the end with a categorical undertaking to import more goods from the U.S., sparking off concerns over the likely trade war between the two countries.
As the trade dispute threatened to blow up into a full scale "war", US Treasury Secretary Steven Mnuchin came under fire from the European Union at the Group of Seven, or G7, meeting of finance leaders in the Canadian ski resort of Whistler. Germany is also hoping its steel exports to the United States will be exempted from sanctions.
