There is a deadly factional war going on INSIDE the CCP.
Xi is battling against an entrenched and powerful rival clique, centered around Jiang Zemin and his gangster heirs. Likely, this Jiang faction is closely allied with the world-wide cabal and its multitude of criminal organizations, etc. Soros is definitely included in that group.
Perhaps Xi feels strong enough now to begin explicitly drawing lines and pointing fingers, publically defining such things that were suppressed out of necessity before.
