The agenda of such meeting should be setup in amicable fashion to express a tone of goodwill, friendship and in cooperative spirit. The agenda would start with news briefs by the Federal President in transparent, declassified only to leaders of the FMSs, and with solicitation for regional support for the efforts and operations of the FGS. This approach would break the logjam and release political tensions. This would be followed by briefs from the state leaders. Brief discussions on important policy options and responsibility- sharing would conclude the first part of the agenda, after which a lunch break would follow this confidence building session. The rest of the agenda would resume after a nice lunch together and informal chat.
To start the hard part of the agenda, all possible options must be put on the table in the form of relaxed and sincere approach for collective decision-making and in amicable brainstorming to look into possible resolutions of the issues and problems. Every idea proposal by anyone should be encouraged and improved in non-confrontational way.
Such platforms in any setting would likely produce positive results. Avoid dry and formal scripting of agenda in an atomoshere of political tension. There must be collective ownership of the issues and problems.
