Medvedev was right to raise this issue, after all, he is from the Government side, where the bulk of the annual Finance budget is spent.
Now that Wang Ye has set up this new Department, it's clear that it's intended to be directly under the Kremlin, isn't it about to squeeze the Government's budget? So he must first clarify this matter.
Grezlov also nodded in agreement, "Indeed, I do not oppose the establishment of a new department, but how will the financial issue be resolved? Surely, we cannot reduce other departments' budgets, as that might result in more loss than gain."
It is rare, but Grezlov and Medvedev hold the same attitude on this issue...
It isn't that they are teaming up against Wang Ye or anything; public matters are public matters, and personal relationships remain personal.
