"None of us can remain silent to the arbitrary cancellation of commercial agreements, the spreading prevalence of protectionism and the use of economic sanctions as weapons," Erdogan said, speaking before the United Nations General Assembly on Tuesday.
"We are in favor of solving our problems through conducting a constructive dialogue on equal terms," Erdogan added.
In a veiled attack presumably aimed at Washington, Erdogan pointed to attempts by some countries to "create chaos" in the world.
"It is very easy to create chaos but it's difficult to reestablish order, and today some countries are persistently trying to create chaos," the Turkish president lamented.
Erdogan also directed his criticism toward the UN itself, saying the body risks becoming an organization with a "reputation for failure" and that it had "moved away from the capacity to meet the expectations of humanity through peace and welfare." The UN, he said, needs to be restructured to better accommodate the interests of its non-Security Council members.
President Erdogan and President Donald Trump reportedly held a brief "on the go" meeting on the sidelines of Tuesday's General Assembly meeting, Turkey's NTV broadcaster reported. Earlier, Turkish media denied that Erdogan had demonstrably left the room of the General Assembly when President Trump began to speak, saying his leaving was connected to his going into another room to prepare for his own speech.
