At the end of the article it gives the names of all attending but not sure it includes everyone because it says "among other officials" at the end. I was looking for Hitcher's name in there to be at Miraflores also but don't see it. However I do believe I posted this article last week when the Chinese delegation first arrived and they did spend some time with Hitcher:
