The CIA has established a new office focused on China as part of the Biden administration's escalating attempts to fight what the US intelligence agency's leader has described as its "increasingly antagonistic" government.

CIA Director Bill Burns announced the expansion on Thursday, saying the agency would be "in the vanguard" of "facing our hardest geopolitical task in a new era of great power rivalry."

“[The China mission centre] will further strengthen our collective work on the most important geopolitical threat we face in the 21st century, an increasingly adversarial Chinese government,” Burns added.

The establishment of the new mission centres is the latest example of the US government attempting to refocus its international, security, and intelligence-related activities on dealing with China, which President Joe Biden has stated is the top priority of the US.

The modifications bring the total number of CIA mission centres to 12. Working groups having a regional focus, such as those dedicated to Africa or the Middle East, as well as topics like as counter-terrorism and counter-proliferation, are examples of these.

The Biden administration is planning to fold two mission centres created under the Trump administration dedicated to North Korea and Iran, respectively into existing regional mission centres in the next 90 days, according to a US official.
