This is a direct request for information on specified matters. Such information may be helpful in designing a way forward or it may be essential to taking any step forward.
The information requested should be as specific as possible. It is not much use asking for 'all the information' in some general area.

Asking for information is a common delaying tactic, so it should be explained why the information is so important.

If it seems that one party is deliberately withholding information then that information can be asked for directly.
