MANFOD
It's 6 points in each country.
As for your other questions, re cargo flights and Hainan Airlines I don't know the answer. I would assume that Hainan would be included, as the definition in the ASA is based on airlines controlled by each country's nationals.
Your point about airlines perhaps not being prepared to take a risk on MAN is a fair one, and in that respect perhaps the frequency limit does indeed have an insidious effect even if it is not currently biting.
