Sorry I disagree, as for some reason, CITES offices in various locations are following US policy as well (Japan being one- try sending any paph there, even with a CITES export cert). I recently spoke to CITES in two other countries and they said, that Paphs of Vietnamese origin in flask would be refused export, inc hybrids.
In some countries in SE Asia, phytosanitary responsibilities overlap with CITES matters due to the way the local agencies issuing certs relate. When inquiring I got told in a muddled way that the US and Vietnam had issues with each other over Viet species and even flasks would not be considered. So then the question is does CITES follow its own rules or the USA, on a country per country basis. I've sent FS Paph hangianum, and hybrids in two countries, sent and accepted by the recieving, yet rejected for export in another.
From what I have been told, Vietnam did legally export several paph species, but later retracted the decision. That has come from people involved in Paphs in Vietnam and outside. Seems to be a bone of contention that can not be proved either way though.
I took the hangianum matter to be there are plants in China. Now thats is as I put it in my email that they exist there. I am told this has been proven by multiple experts, but at this time, I can not say more as I am not a liberty to say how and by whom. If it comes to fruition, all will know soon enough I guess. I was told it in the pipeline by people I trust.
My issue with CITES Mick is that CITES offices from country to country seem to interpret rules and add other issues to them as they please. Some interpret it so laxly that is a joke, other go overbboard and make it impossible to export species that are common even. I have been in two offices where I had to educate staff as to the appendix value of a plant.
