Survivors of the U.S. atomic bombings of Hiroshima and Nagasaki on Sunday welcomed Democrat Joe Biden's victory in the U.S. presidential election, and hope that negotiations on nuclear disarmament will advance under his administration.

Survivors of the 1945 bombings of the two cities expressed expectations that Biden, a Democrat who defeated Republican President Donald Trump in Tuesday's poll, will address the issue of nuclear weapons after he takes office in January next year.

"We expect to see progress in negotiations on nuclear disarmament after a change of president," said Kunihiko Sakuma, head of a Hiroshima-based group supporting survivors and himself an A-bomb victim.
