Miles Kwok aka Guo Wengui (Chinese billionaire) was “red-noticed” by Interpol for corruption charges coming out of China (red). He has been living in New York. This was at the end of April. Recent tweets in October showing lunch’s with Bannon. Last tweet was Nov 22, 2017. Nothing since.
China/US do not have an extradition treaty but Kwok seems like a key sacrificial pawn for the green light to move on NK from China.
A trade of sorts.
In the April 19 VOA interview, Guo claimed to hold passports from the US, EU and nine other foreign jurisdictions.
