I don't know the answer to that question. However I do know that I am invited by Canada and Quebec to participate.
I regularly receive invitations to take part in trade missions. Some of them are to France, Brazil, etc. Some of these places are excellent countries with which to establish good business partnerships, but there are also countries where you know there is a culture of non-compliance. I find this completely unacceptable. I told them to stop inviting me, because I don't ever want to go. Agreeing to go means agreeing to transfer my technology, my knowledge and my clients' needs directly to those companies.
Who pays? Perhaps the Asian government pays a portion of the costs, I don't know. One thing is clear, the Government of Canada is the party extending the invitation to take part in these trade missions.
