Noting that recent crisis in Europe show that the continent remains at risk from new outbreaks of conflict, Guterres said, "Within Europe, there are serious unresolved, protracted conflicts, while new threats and challenges are emerging."
"Populism, nationalism, xenophobia and violent extremism are both causes and effects of conflict," he said.
Noting that no single factor is responsible for the emergence and continuation of conflicts, he said that in many cases, peace agreements were "simply not being implemented."
"Whatever the causes may be, the inability of regional and international institutions, including our own, to prevent and resolve conflicts is seriously undermining their credibility and making it more difficult for them to succeed in future," the UN chief said.
He said crisis in Europe could also adversely impact economic progress and sustainable development.
He called on Member States, the Security Council and regional mechanisms to intensify their efforts to define a peace and security agenda to address today's complex challenges, stressing that "the status quo is not sustainable."
Speaking specifically on the conflict in Ukraine, Guterres said, the UN remains committed to supporting a peaceful resolution, in a manner that fully upholds the sovereignty, territorial integrity and independence of Ukraine, and in accordance with relevant Security Council and General Assembly resolutions.

Assembly President Peter Thomson said it is challenging to see how far the world is from winning the global fight against racism, xenophobia and related intolerance.
Even though global migration had long been a feature of human history and forcible displacement had driven large number of people from their homes, refugees and migrants too often are met with suspicion, fear and intolerance.
"The world must reaffirm its faith in the International Convention on the Elimination of All Forms of Racial Discrimination and the Durban Declaration and Programme of Action," he said, adding that the Universal Declaration of Human Rights called on the world to fight racism, xenophobia and hate where and whenever it appeared.
