The second was hilarious, Pang seems a pure acolyte of Putin and Xi...may not be wrong on isolated points...but overall it's impossible to ignore his bias.
And the latter is, well...picking the overripe low-hanging fruit of Neo-Keynesian excess...and that bitter fruit goes back to tainted seed planted in 1913...it has nothing at all to do with the brilliance or lack thereof of Xi's Communist Kleptocracy or Czar Vlad Putin I's Neo-Imperialist Russian Oligarchy...
