United Nations Secretary-General António Guterres warned Tuesday that the world is facing a "trust deficit disorder," and that the only way to confront global problems is through multilateral cooperation.
"The world is more connected, yet societies are becoming more fragmented. Challenges are growing outward, while many people are turning inward," Guterres said during an address to the United Nations General Assembly.
"Multilateralism is under fire precisely when we need it most," he added.
Guterres -- who has been critical of some of President TrumpDonald TrumpHeadaches intensify for Democrats in Florida Stormy Daniels set to testify against former lawyer Avenatti in fraud trial Cheney challenger wins Wyoming Republican activists' straw poll MORE's policies and fading U.S. influence in the world -- urged world leaders in attendance to collaborate to promote peace, human rights and economic and social progress. His remarks drew applause as he implored the audience to avoid becoming complacent as authoritarianism rises around the globe.
He additionally highlighted climate change, growing inequality and the abuse of technology as global challenges in need of solutions.
"In the face of massive, existential threats to people and planet -- but equally at a time of compelling opportunities for shared prosperity -- there is no way forward but collective, common-sense action for the common good," Guterres said.
The U.N. leader's speech struck a markedly different tone from President Trump, who repeatedly emphasized the need for each nation to carve its own path in the world, and suggested the U.S. would no longer provide financial or military support to those who don't provide something in return.
Trump spoke before Guterres at the general assembly in New York City.
"America is governed by Americans," Trump said. "We reject the ideology of globalism, and we embrace the doctrine of patriotism."
"Only when each of us does our part and contributes our share can we realize the U.N.’s highest aspirations," he added. "We must pursue peace without fear, hope without despair, and security without apology."
