The statement, which came today at the end of an annual gathering of the peace prize winners, also called for negotiations to end armed conflicts in Syria and elsewhere.
The winners met in Warsaw this year to mark 30 years since Lech Walesa won the prize for leading the Solidarity movement, which helped topple communism in Poland.
A special guest was actress Sharon Stone, who was honored for her work to fight HIV and AIDS.
The meetings were initiated by former Soviet leader Mikhail Gorbachev in 2000.
