The two strategic rivals also discussed the fraught issues of Taiwan and the South China Sea, according to CCTV.

"Any attempt or interference to use force to support independence or use Taiwan to contain China will be thwarted," Dong Jun told US Secretary of Defense Pete Hegseth during a video call.

China considers self-ruled Taiwan part of its territory and has not ruled out the use of force to take it, while Washington is the democratic island's main arms supplier and is committed to its defence.

Hegseth "made clear that the United States does not seek conflict with China nor is it pursuing regime change or strangulation of the PRC," Pentagon spokesman Sean Parnell said in a statement, referring to China by the initials of its formal name.

"At the same time, however, he forthrightly relayed that the US has vital interests in the Asia-Pacific, the priority theater, and will resolutely protect those interests," Parnell added.

In the South China Sea, Dong said Beijing "firmly opposes infringement and provocation by certain countries and the deliberate incitement of chaos by countries outside the region," CCTV reported.

China claims almost all of the South China Sea, despite overlapping claims with its neighbours.

The US Navy has regularly sent ships to conduct "freedom of navigation" transits in the region, angering Beijing.

"We must... build an equal, respectful, peacefully coexistent, stable and positive military-to-military relationship. We must respect each other's core interests," Dong said.

The Pentagon said the talks were "candid and constructive", with Hegseth and Dong agreeing to further discussions.
