Asia-Pacific economies look forward to progress in trade talks between the US and China

Wei said the concerns over US-China investments should include the US regulators often citing strange grounds to pour cold water on Chinese investors' plans. A processed meat producer from China is even barred from buying plots of land for pig-raising purposes in the US on the ground of "national security concerns".

On the other hand, US investors are occupying the most booths in China's import fair in November and small and medium-sized US businesses are eyeing opportunities in the world's largest market.

Other guests in closed-door panels also offered constructive suggestions for nations to come together for a world that is more balanced, more inclusive, and fairer, said Zhang, who has attended all panels.

Many have realized that China may have different approaches in reforming current economic and diplomatic mechanisms but has been willing to discuss with others, he added.

Das also stressed in an interview with China Daily that China and the US need to work together, noting that breaking the global supply chain "is bad for everybody". Given the global impact of the US-China trade conflict, more dialogues should be held to include other stakeholders, he said.

Das, who once served as director general of the Confederation of Indian Industry, said the China-US trade conflict has affected everyone connected in the global supply chain, especially Asian countries as they're deeply connected with both the US and Chinese economies.

"We are all experiencing pain," he said, noting that "the pain is not bilateral only. It has become multilateral".

"Innovation depends on openness," Das said, adding that all the technological development has relied on the knowledge sharing among nations.

He reiterated the concerns earlier expressed a day earlier by Zeng Peiyan, chairman of the CCIEE and former Chinese vice premier, on how some sectors' calls for decoupling will damage the interests not only of China and the US, but the rest of the world.

He said US government's decision to blacklist Chinese telecommunications company Huawei is one example on how the trade conflict is affecting the technological sector.

The US Department of Commerce has put Huawei and other Chinese technology companies to its "entity list", which restricts their access to US technology.

Bert Hofman, director of the East Asian Institute in LKYSPP, said the US might argue that putting up an 'entity list' doesn't contravene the rules set by the World Trade Organization (WTO) as there's a security issue involved. But he said this point debatable and should involve not only the two countries but other affected stakeholders as well.

Speaking with China Daily, Hofman said the issue of Huawei alone "affects many countries and even US companies because Huawei has a big supply chain".
