CHIBA — Altering the war-renouncing Article 9 of the Constitution could threaten the safety of Asian people and trigger a regional arms race, Nobel laureate Mairead Corrigan-Maguire told a symposium Sunday.

Speaking at the Global Article 9 Conference to Abolish War held in Makuhari Messe in the city of Chiba, the winner of the 1976 Nobel Peace Prize expressed distress over recent moves to revise the Constitution.

"Many of us are concerned to know that there are those, both in the government and the wider Japanese society, who wish to endanger such peaceful policies and abandon Article 9 and Japan's peace Constitution," Corrigan-Maguire told the packed convention center.
