I have the reason for the cancel made on the Round One tournaments below from a very good source.
Group N- UAE, Kyrgyzstan, Hong Kong, Kuwait, Georgia
Group O- Thailand, Chinese Taipai, Bosnia, South Africa, Iran
Both UAE and Thailand the original hosts declined to host the tournaments. IIHF then determined after checking with the other 8 that none were willing to host or simply did not have acceptable rinks to host. Thus unable to find a acceptable host for these two tournaments the IIHF cancelled them. To me totally unacceptable. Says much that you can't find some place to play thus the original two turned it down getting a automatic advance.
