UAE president Sheikh Mohamed bin Zayed Al Nahyan greeted Lula at the presidential palace in Abu Dhabi, where a 21-gun salute rang out and formation jets trailed Brazil's national colours.

Lula, who returned to power in January after two terms as president between 2003 and 2010, was played the Brazilian national anthem and inspected an honour guard.

He was due to attend an "iftar" dinner -- the daily fast-breaking meal during the Muslim holy month of Ramadan -- and will leave early on Sunday, officials said.

The strategically located Gulf monarchy is Brazil's second-largest trading partner in the Middle East, according to the official WAM news agency.

Bilateral trade excluding oil products totalled more than four million dollars last year, representing a 32-percent rise from 2021, WAM said.

In Beijing, where Lula sought to consolidate economic ties with Brazil's main trading partner, he said his country was "back on the international stage" and ready to mediate an end to Russia's war in Ukraine.

Lula also accused the United States of "encouraging" the war and said it should "start talking about peace".

Both China and Brazil have refused to join Western nations in imposing sanctions on Moscow for its invasion, and there are concerns in the West that both potential mediators are overly cosy with Russian President Vladimir Putin.

The UAE has maintained a neutral stance in the conflict.

Its financial hub Dubai has attracted Russian professionals and businesspeople fleeing the impact of Western sanctions since the invasion in February 2022.
