(Reuters) -Beijing and Washington are expected to extend their tariff truce by another three months at trade talks in Stockholm beginning on Monday, the South China Morning Post (SCMP) reported on Sunday, citing people familiar with the matter.

During the expected 90-day extension, the U.S. and China will agree not to introduce new tariffs or take other actions that could further escalate the trade war, the report said.

While the earlier discussions in Geneva and London focused on "de-escalation", the latest meeting the Chinese delegation will also press Trump's trade team on fentanyl-related tariffs, the report further said, citing three sources familiar with the matter.

Reuters could not immediately verify the report. The White House did not immediately respond to requests for comment.

The third round of U.S.-China talks is set to be held in Stockholm on Monday to tackle longstanding economic disputes at the centre of the countries' trade war.
