Indian Finance minister Pranab Mukherjee said that differences between Pakistan and India may be resolved one day since the two cannot wish each other away and live in "perpetual tension".

"I do not have the capacity to indulge in the romanticism that like Berlin Wall, one day the differences may go. How the course of history will take turn, nobody can predict with that precision. It may happen," he said in New Delhi on Tuesday night at the launch of eminent journalist M J Akbar's book.

Describing Pakistan as India's "most important" neighbour, he said, "The stability and well-being of Pakistan" is in the interest of this country as the two could not develop and prosper in isolation today".
