According to notes on a U.N. list of speakers, Castro is expected to address the General Assembly on Sept. 28, the same day President Barrack Obama is scheduled to speak. The two leaders had their first formal meeting in April, just months after announcing Cuba and the U.S. would restore diplomatic ties following generations of adversarial relations.
Castro will join more than 160 heads of state and government at the meeting. Chinese President Xi Jinping, Russian President Vladimir Putin and Iranian President Hassan Rouhani will also be speakers.
The U.N. has not indicated what the Cuban president will discuss in his talk.
