The European Union apparently prefers to maintain sanctions at the expense of peace talks

The peace talks were supposed to happen today.
I may be wrong, but they withdrawn from the talks because the e.u., warned in advance, still refused to withdraw their sanctions, otherwise these discussions would have probably happened(, unless it's a convenient excuse from the M23).
What can be expected is that the haughty e.u. will refuse to withdraw their sanctions tomorrow/'this week', even temporarily.

(negotiating still seem in their interests though, no ? It's probably just a part of their revendications and i hope that the e.u. will retract their sanctions accordingly since that's an easy demand to satisfy)
From what i understood, their revendications are towards a tutsi minority that they deem inadequately integrated&protected.
The name of their movement comes from the treaty signed on the 23 March 2009, considered not implemented by the M23.

Europeans may not have been warned beforehand for all i know, and they can't react immediately, like D.Trump, but the 'council of the european union'/'ministers of state-members' can vote by written procedure, it can theoretically be done within 24h
