Such a deal would, however, provide the US Treasury an opportunity to climb down from what currency experts say was a misguided declaration in August that Beijing was a "currency manipulator," reducing the yuan's value to gain "unfair competitive advantage in international trade".
Little is known about the structure of a currency deal that the US Chamber of Commerce said American and Chinese negotiators were working toward on Thursday in their first high-level trade talks since July, but it is widely expected to include a promise from both sides to refrain from devaluing their currencies to gain a competitive trade advantage.
As members of the Group of 20 major economies, both the United States and China agreed to such language starting in 2010.
At that time, China was widely seen to be deliberately holding down the value of its heavily managed currency, also known as the renminbi (RMB). But this intervention shifted to mainly prop up the yuan's value after a sharp devaluation in 2015.
It is unclear how a pact with the United States might change Beijing's behaviour.
"In essence, I don't see anything in a currency deal that will cause a significant change in the present RMB/dollar currency market dynamics," said Mark Sobel, a longtime former Treasury and International Monetary Fund official who is now US chairman of the Official Monetary and Financial Institutions Forum, a London-based think tank.
Myron Brilliant, head of international affairs at the US Chamber of Commerce, said a currency deal would likely be accompanied by the United States' cancelling a planned tariff increase to 30% from 25% on $250 billion in Chinese imports.
A US official confirmed that currency would likely be discussed in the talks, but it was premature to say whether an announcement would be made on the issue this week. Optimism over the talks had improved after the first day's negotiations wrapped up.
