Berliner Tageblatt - CIA chief made secret trip to Beijing last month: US official

"Last month, Director Burns traveled to Beijing where he met with Chinese counterparts and emphasized the importance of maintaining open lines of communication in intelligence channels," the official said on grounds of anonymity.

The official provided no other specifics on the timing of the visit or who Burns met. The Central Intelligence Agency as a policy does not discuss the director's travels.

But the visit came as Washington struggles to improve relations with China amid tensions over Taiwan's status, with both sides warning over the danger of a military conflict.

Washington has also accused China of considering supplying military goods to Russia in support of its invasion of Ukraine, which China denies.

Earlier this year US Secretary of State Antony Blinken cancelled a long-planned ice-breaker trip to Beijing after a Chinese surveillance balloon crossed the mainland United States, flying above sensitive military bases before it was shot down by a US fighter jet.

Blinken still hopes to go, State Department officials say, when conditions improve.

Earlier Friday US Defense Secretary Lloyd Austin and his Chinese counterpart Li Shangfu spoke briefly at a security forum in Singapore, after many months in which the two sides' militaries had not communicated directly at a senior level.

Their short conversation came after Beijing had declined the Pentagon's invitation for a formal meeting in Singapore.

The United States has also infuriated Beijing by restricting US exports to China of advanced microchips, chip technologies and manufacturing equipment, pressing allies to side with Washington.

And Washington has faulted China for not doing enough to halt exports of chemicals that are turned into deadly fentanyl in Mexico and sold in the United States.

China, for its part, has put pressures and limitations on some US businesses operating in the country, underscoring the competition between the world's two largest economies.

At the G7 meeting in Japan last month US President Joe Biden predicted that ties between Washington and Beijing would soon thaw, after the February balloon incident.

After that, "everything changed in terms of talking to one another. I think you're going to see that begin to thaw very shortly," Biden said in Hiroshima.

On Friday White House National Security Advisor made a separate overture to Beijing, saying it should be part of nuclear arms pacts between the United States and Russia owing to the rapid buildup of its nuclear warhead supply.

In terms of trying to agree on limitations, "We're also ready to engage China without preconditions," said Sullivan.
