According to the last link, the surveillance is limited to the TOM-Skype client and not the standard Skype client. If one of the party in the communication uses the TOM-Skype client however, the session is monitored (according to the report, second link):
"The TOM-Skype software from skype.tom.com contains a keyfile that appears to be an encrypted list of banned keywords as well as a filtering component created by TOM Online. When a TOM-Skype user sends or receives a text chat message that contains a keyword, the message is not displayed. However, when such a message is sent or received by a TOM-Skype user an HTTP connection is made to a TOM-Skype server and encrypted data is uploaded. These messages are stored in log files on the TOM-Skype servers."
