The US and China have wrapped up another round of trade talks without any major breakthroughs, despite discussions that both sides described as "constructive".

The negotiations, held in Stockholm, Sweden came as a truce established in May is set to expire next month, threatening to revive the turmoil that hit in April when the two countries exchanged escalating tit-for-tat tariffs.

US Treasury Secretary Scott Bessent said any extension of that truce, in which both sides agreed to drop some measures, would be up to President Donald Trump.

China's trade negotiator Li Chenggang said that both sides would push to preserve that agreement.

Beijing and Washington have been at loggerheads on a range of issues as well as tariffs, including US demands that China's ByteDance sell TikTok and that China speed up its export of critical minerals.
