I don't think it's a particular secret that Keith Bennett has been involved as a business consultant specialising in China and North Korea. If as we've always argued that more trade with socialist (or would-be socialist countries) is preferable to sanctions and war I can't see a problem.
But the idea that KB is brokering huge deals on behalf of the Chinese state and the DPRK is a little ludicrous. The countries share a common border, do they need a Westerner to filter money through western-listed companies and bank accounts? Given the US strategy of trying to disrupt and block DPRK banking and trading deals that would be a stupid strategy.
The DPRK desperately needs assistance to improve its economy and clearly doesn't have the internal expertise to work well with western companies (for reasons we could debate for hours)equally few western investors know anything whatsoever about the DPRK. If KB can act as a link, good luck to him.
But rather than drag the discussion down to the usual personal level it might be of interest if others on the list could recall similar things in the past. Communist businessmen were at the forefront of helping to break down cold war trade barriers with many countries, including China. The Austrian CP was one of the richest CPs in the world per capita due to a party-run firm that dominated Austrian-Comecon trade. Did the CPGB have much in the way of party-controlled companies that worked in this way? I'm not talking about examples like Progressive Tours but actual trading entities.
