US negotiators arrived in Shanghai on Tuesday to resurrect trade talks with Chinese officials, with both sides downplaying expectations of an imminent deal between the world's two biggest economies.
The negotiations in the financial hub will be the first face-to-face discussions since US President Donald Trump agreed to a truce with Chinese President Xi Jinping at June's G20 summit after previous talks broke down over the US accusations that China reneged on its commitments.
Washington and Beijing have so far hit each other with punitive tariffs covering more than $360 billion in two-way trade, in a tense stand-off centred on demands for China to curb the alleged theft of American technology and provide a level playing field to US companies.
Vice Premier Liu He will likely lead the talks for China again, with the two sides expected to meet later Tuesday ahead of a full day of talks on Wednesday.
The negotiations come as Beijing faces heavy pressure over ongoing civil unrest in Hong Kong, and with lingering ill-feeling between the US and China.
Days before the Shanghai meeting, Trump threatened to pull recognition of China's developing nation status at the World Trade Organization prompting an irritable reply from Beijing about the "arrogance and selfishness" of the US.
Trump said Friday he believed Chinese negotiators were hoping to delay a deal until after the US presidential election next year, adding: "When I win... they're all going to sign deals."
The US leader has also angered the Chinese side by claiming the slowing economy is forcing them to make a trade deal, and blacklisting telecom giant Huawei over national security concerns.
In a commentary on Tuesday, state news agency Xinhua admitted relations were "strained" and called for the US to "treat China with due respect if it wants a trade deal".
But the kick-starting of trade negotiations are still being seen as positive even if little of substance is expected following a truce agreed between Trump and Chinese President Xi Jinping at the G20 in June.
"Realistically, this round of talks is about clarifying where the two sides stand after a significant lull in engagement," said Jake Parker, senior vice president at the US-China Business Council.
"There also needs to be a focus on rebuilding the trust that was present in April but has since dissipated."
Holding talks in Shanghai is also a nod to a time of better relations, as the city was the home of the 1972 Shanghai Communique -- an important step in building diplomatic relations between the US and China.
Chinese Commerce Minister Zhong Shan, who is seen as a tough negotiator, is expected to join Liu on the Chinese side.
"Minister Zhong Shan, like Liu He, is a 19th Party Congress Central Committee member, so his involvement would indicate an elevation of participation on the Chinese side," said Parker.
"His appointment could offer another senior voice... on the Chinese side."
'Lot of issues'
But both sides were busy lowering expectations in the run-up to talks.
Mnuchin told CNBC last week there were still "a lot of issues" while Chinese state-run daily The Global Times wrote that it is "widely believed that trade talks will take a long time".
There was no sign of the rhetoric letting up either, with the China Daily newspaper's Tuesday editorial saying "the US should give its go-to tactic of maximum pressure a couple of days off as it has proven ineffective against China".
It pointed to an announcement at the weekend that China would buy more US agricultural products including pork, cotton, and soybean as a sign of China's "goodwill" and called for the US to "reciprocate if it wants any progress to be made".
There are likely to be "modest soft-pedalled concessions", said Stephen Innes, managing partner at Vanguard Markets Singapore, such as a pause of further tariff increases on Chinese exports to the US.
"Following another month of escalating tensions, agreement on practically anything will be a positive," said Innes.
US Trade Representative Robert Lighthizer and Treasury Secretary Steven Mnuchin arrived in Shanghai on Tuesday, a source close to the talks told AFP.
