"In particular, we must collectively thank the government of the Federal Republic of Germany under the commendable leadership of Chancellor Angela Merkel and the governments of Italy, Greece and Turkey for assisting hundreds of thousands of refugees", Buhari said.
Mr. Buhari similarly praised the global community for delivering security and humanitarian assistance in the Sahel and Lake Chad regions, which have been ravaged by terrorism.
The 1.1 million-strong Rohingya people have suffered years of discrimination in Myanmar, where they are denied citizenship even though many have longstanding roots in the country.
He specifically praised the UN Security Council for humanitarian assistance and pledges in the Lake Chad Basin.
He also highlighted Nigeria's efforts to provide relief to citizens displaced by Boko Haram violence and environmental challenges such as droughts. "Each State has one vote, like a democracy".
Buhari says the worldwide community needs to work together to stop Islamic State extremist fighters from infiltrating into areas of Africa's Sahel region where "response capacity is weak".
"UN has responsibility to cooperate strongly with regional organisations such as African Union, in conflict prevention and management".
The rest of the speech was devoted to repeating points other world leaders have made regarding the nuclear threat presented by North Korea, the purported genocide of Rohinyga Muslims, issues between Palestine and Isreal without focus on critical issues affecting Nigerians.
Zuma's accompanied by an entourage of five ministers and he'll sign the treaty on the prohibition of nuclear weapons.
