After the tariff talks in Stockholm between China and the US in July, Beijing expressed optimism and said that both parties were working to extend the tariff pause by another 90 days.
The negotiators from the US, however, referred the matter further and said that it is up to President Donald Trump to decide on a potential extension of the pause.
So far, Trump has not given any indications whatsoever about which way it is leaning, which creates concern that the tensions between the world's two largest economies will worsen again, reports CNBC.
In May, the US and China agreed on a 90-day pause for further tariff increases to create time and space to reach a long-term sustainable agreement.
The tariff pause meant that the US, after the shock increase to 145 percent in the spring, now has tariffs on Chinese imports of 30 percent. China has lowered from 125 to 10 percent.
Even though it is uncertain until the very end whether the tariff pause will now be extended, analysts expect that a summit between Trump and Xi will take place in Beijing in the coming months.
