Chinese officials have said they are “confident in implementing” trade commitments made to the US “as soon as possible”, without giving details.
An ongoing trade war has seen both countries impose duties on billions of dollars of one another’s goods.
Over the weekend, a temporary truce was agreed between US President Donald Trump and Chinese President Xi Jinping at the G20 meeting in Argentina.
But concerns linger over discrepancies in information coming from either side.
The US and China paused hostilities after several months of tit-for-tat tariffs, agreeing to halt any new duties for 90 days.
This prevented a widely expected escalation in the trade war. Tariffs already imposed on Chinese goods had been due to rise at the start of the year and additional tariffs had also been threatened.
Since the talks, Mr Trump had taken to Twitter with details – but some of the information did not tally with what White House officials were saying, and Beijing had not commented at all.
The confusion has left many wondering whether the talks will succeed in ending a trade war, which was already hurting industry and many feared would derail the world economy.
