Chinese Visa Problems

Due to the Olympics, the Chinese official's have stopped issuing multiple or double entry visa's to Australian citizens... this has thrown a spanner into my plans to fly into China, take a train to Ulaanbaatar, Mongolia from Beijing, then back into China and back home via Thailand... as a result, I need to acquire a new Chinese visa on my arrival in Ulaanbaatar, Mongolia... the risk is that the Chinese will stop issuing all new visa applications and I'll be stuck in Mongolia, with no way to get back into China to connect with my Beijing flight home...
