His comments come amid a strain in ties between the BJP and ally TDP, which has expressed disappointment over the Union Budget saying it did not offer anything to Andhra Pradesh, where it is in power.
Raju told reporters here that leaders of both the parties are "attuned" to these sensitive issues and trying to find solutions.
"When Andhra Pradesh was divided, what was left was a residue state of AP. Now, residue gives a lot of impressions. There are certain commitments that were made.
He said the state was divided "unscientifically".
"The idea is that you divide a state during the last days of Parliament before an election, it generates a problem. And that is what has happened. That problem requires attention and I think it will come," he said.
