Ask them a bullet point list of what action points would they hope to set as a result of this meeting. Both for themselve and you. This will provide you with 2 defense lines: 1)They have to make an extra investment in this meeting.

This actually works for all types of meetings. I've seen a radical decrease in invitations and time spent at meetings,
