Prayut was welcomed by Thais resident in the US who travelled from various states to greet him with roses. They also wore white T-shirts printed with the message "We love you uncle Tu [Prayut's nickname]".
On Tuesday, Prayut is scheduled to attend a banquet hosted by UN Secretary-General Ban Ki-moon before attending an event to celebrate the first anniversary of the endorsement of the UN sustainable development agenda.
Prayut would later hold bilateral talks with King Abdullah II of Jordan before attending the first summit on refugees presided over by US President Barack Obama. In his speech, the Thai premier would address his government's efforts and plans to deal with the issue.
