We now categorize Taiwan, Hong Kong, and Macao as regions of China. We have updated the default text values for the Country field in Event Registration to the following: Taiwan (Republic of China), Hong Kong (China), and Macao (China).
The SOAP object definitions and country codes have not changed. However, clients using the Cvent SOAP API will see different values for these countries if users or attendees have selected them in Event Registration for the following objects: Contacts, Events, Guests, and Registration.
