"I am a constant supporter of handling the next budget proposal in such a way as to preserve the EU's existing values," he said.
Those values are reflected in a "cohesion policy," which Commission President Jose Manuel Barroso said had not changed.
"The commission will of course remain committed to strong economic, social and territorial cohesion. That has always been our firm position," the EUobserver quoted Barroso as saying Wednesday.
The issue is especially critical in Poland, which is scheduled to receive $85.7 billion in cohesion funds to cover 2007 through 2013.
In a financial downturn, however, states are tested as to how much they will support other nations.
Barroso said recently "deepening integration" among member states relied on cooperation of "all European states."
