Communication or engagement

As we are in the process of writing a new communication strategy, I was interested to read these thoughts from Andrea Di Maio, a VP at Gartner specialising in e-government, particularly
"In essence, an effective communication strategy is likely to be almost the exact opposite of an effective engagement strategy"

I'd always assumed good communication had to include some engagement, but I can see his point about the difference between communication where you are in control, and 'real' engagement where you have less control. Though whether you should have two separate strategies, I'm not sure. I'd be very interested to read other people's thoughts on this.
