N no kankei de is used to refer to causal relationship in a very indirect way.
In fact, the noun kankei means 'relationship' and the particle de indicates a
causal relationship. (+ de3 (DBJG: 107-09))

[Related Expression]
The following sentences are saying virtually the same thing, but they are
slightly different from each other.

Among the five choices, N no kankei de is the most indirect reference to
causal relationship, because it does not need to be specific about the cause
(i.e., (lack of) budget funds in [la] and [lb]). N no tame (ni) is next most
indirect about specification of the cause. Exs.[lb] and [lc] show that the
preceding N can be a neutral yosan 'budget' or a negative yosan-busoku
'lack of budget.' N de, kara and node all requires a specific cause. In this
sense they are markers of direct reference to causal relationship. Among de,
kara and node, the latter two are markers of more direct reference to causal
relationship.
(+ tame (ni) (DBJG: 447-51); node (DBJG: 328-31); kara3 (DBJG:
179-81))
