Japan have already qualified as hosts, while the Iranian men's team earned their spot at the ParaVolley World Championships last July.
"I am looking forward to attending our Zone Championships to see our athletes perform and meeting as many of you as possible," said PVAO President Lu Cailiang.
"Good luck in your planning and preparations."
