China's international trade representative Li Chenggang said the talks in Stockholm were "candid, in-depth, constructive", according to state news agency Xinhua.

US President Donald Trump sparked the trade dispute after returning to office earlier this year, leading to escalating tariffs on both sides that reached triple-digit levels, throwing businesses and supply chains into disarray.

The two countries exchanged views on major trade and economic concerns, Li said, and are due to maintain close communications.

The US delegation, led by US Treasury Secretary Scott Bessent, has not yet issued any statements over the talks.

The negotiations are happening in the wake of a US-EU trade deal struck over the weekend that set US tariffs on most EU imports at 15 percent, but none on US goods going to the European Union.

The truce between China and the United States, the world's two largest economies, has temporarily set US duties on Chinese goods at 30 percent, and Chinese levies on US ones at 10 percent.

That accord, reached in Geneva in May, brought down the tariffs each side had levelled at the other after Trump embarked on his trade war.

The 90-day truce is meant to end on August 12, but there are indications both delegations want to use the Stockholm talks to push the date back further.

The South China Morning Post, citing sources on both sides, reported Sunday that Washington and Beijing were expected to extend their tariff pause by a further 90 days.

- Trump threats -

Trump has threatened to hit dozens of other countries with stiffer tariffs starting Friday unless they agree to trade deals with Washington.

Among them are Brazil and India, which he has warned could be targeted for 50 percent tariffs.

Trump has already announced deal outlines with five countries -- Britain, Vietnam, Japan, Indonesia and the Philippines -- as well as the one with the 27-nation EU.

Beijing says it wants to see "reciprocity" in its trade with the United States, and foreign ministry spokesman Guo Jiakun said dialogue was needed "to reduce misunderstandings".

The previous round of China-US talks was held in London.

Analysts say many of the trade deals Trump has been publicising are leaning more on optics than on details.
