how to obtain visa from belize

Hi, I am a Belizean living in Belize and will be attending a seminar in China next month for the Nanjing Youth Olympic Games but we have no Chinese embassy here, where can I apply for it? Is there a possibility of applying online? Where can I obtain the application form? What are the requirements? What type of form is it as someone told me that there are V2011A, V2011B, etc. Your most urgent reply will be appreciated. Thanks
