Burns has been anti-China from the start and Biden sent him to improve communications between the US and China...? I guess they kept this meeting secret because the Western media would be blaring how the US sent him to confront China and about improving relations. Maybe China should've arrested him since the US admits they had spies in China for them to be "executed" that the US complained about. Look at how how angry the US is over how dare China has "policeman" working in the US.
Burns' visit was to size up his adversary...
China therefore needs to get fully ready for kinetic confrontation, double time.
