The budget is also overseen by the Krai Ministry of Economics and Regional Development, which is responsible for implementing regional policy measures that imply inter-regional co-operation. During the 1990s, it was opaque, largely ad hoc and focused on: i) supporting the poorest regions, and ii) responding to political pressure from stronger regions for fiscal privileges and greater autonomy. This changed in the early 2000s as bilateral agreements between the centre and the regions were scrapped and the system of fiscal federalism was reformed.
