Existing In-Country Agreements on Coordinating Technical Assistance?

Hi,

I am doing some background work to try to find good practices in establishing joint local agreements to manage donors' technical assistance, so for example covering things like working from an agreed national strategy, harmonising per diems, not poaching Government staff, etc. Has anyone got any examples to share? I'm looking for real-world examples as opposed to the EU's guiudliens etc which I already have :-) 

Thanks!

Andy
