During the ‘50s Korean “Police Action” both China and Russia took sides with NOKO ... Frozen Chosen massed Chinese assaults, MiGs flown by Russian pilots ...
China has said any fallout reaching its North Eastern province will result in an ‘exchange’.
Uh huh.
And nothing’s changed since.
And the Chinese don’t hate the Norks with enough of a passion to round up any Nork defectors they find in China and put them in prison for storage until someone needing new organs is found for the spare parts they can provide.
And China’s most heavily armed border isn’t with Nork.
News Flash:
China went into Nork back in the day because of a deal with the Sovs regarding nuke tech exchange from Sov to China. NOT because of commiescum solidarity or any love of the Norks.
