I think he met if he can join a party? I looked at cyanne list of cants and can and didnt see anything about partying.

You can't create a party (seems dumb and pointless given the purpose of the trade block, but it's Nexon I guess), but this really doesn't matter since you can just invite anyone without a party to auto-create a party. That's how I always create parties in the first place anyways. You can also create expeditions.
