My take is that China is a member of the deep state, along with some Muslims and what we think of as the Cabal (Rothschilds, etc.)
I also think that this is a temporary partnership. Remember what happened to Barzini at the end of the Godfather? If they get what they want, and take down all the countries, they'll turn on each other.
There is another possibility - remember ... POTUS went to the Forbidden City. At the time it was considered that Kim also went there and was in fact their first meeting. If there’s a deep state in China (separate from CCP) and clowns were running NK ... then that meeting and events since can be seen in a different light
