"The Holy See is doing its part to build a real and concrete fraternity, among peoples and nations," he said.
During a leadership roundtable to prevent and end conflicts, Cardinal Parolin said the Holy See is "firmly convinced of the fundamentally inhumane nature of war and of the urgent necessity to prevent and to end armed conflicts and violence among peoples and States."
At a summit roundtable focused on helping displaced persons, the cardinal noted Catholic institutions' efforts to help relieve displaced persons' physical sufferings and address their material and physical needs.
"The Holy See is committed to advocating for the protection and proper assistance to forced migrants, internally displaced peoples and victims of trafficking, and to working to find durable solutions and reconcile communities," he said.
In his message to the summit, Pope Francis voiced hope that the gathering would make real contributions to lessen the sufferings of millions of people. He called for "a true and profound respect" for those who suffer due to violence, persecution, natural disasters and other calamities.
He especially noted the victims who are most vulnerable and live "in conditions of misery and exploitation."
He asked the summit: "Let us hear the cry of the victims and those suffering. Let us allow them to teach us a lesson in humanity. Let us change our ways of life, politics, economic choices, behaviors and attitudes of cultural superiority."
"Learning from victims and those who suffer, we will be able to build a more humane world," he continued.
The Pope also noted the obstacles to peace.
"We cannot deny that many interests today prevent solutions to conflicts, and that military, economic and geopolitical strategies displace persons and peoples and impose the god of money, the god of power," he said. "At the same time, humanitarian efforts are frequently conditioned by commercial and ideological constraints."
He called for a renewed commitment to "protect each person in their daily life and to protect their dignity and human rights, their security and their comprehensive needs."

The Pope also recognized relief workers who "serve their neighbor and contribute to consoling the sufferings of the victims of war and calamity, of the displaced and refugees, and who care for society, particularly through courageous choices in favor of peace, respect, healing and forgiveness."
"This is the way in which human lives are saved," he said.
