Wang pissed at Mavs??

[Nellie]

This is the latest from hoopsworld:

The Warriors have interest in signing Wang Zhi-Zhi and may help Wang get a big offer from Dallas, who claims they will match, but word also has it Wang was disappointed in how Dallas handled the China Nation team demands, and may be unwilling to re-sign. Mavs sources doubt there will be an issue, and say talks are awaiting Wang's selection of a new agent.

Why would Wang be pissed at us over that? Is this negotiating smoke?
