Sheikh Mohamed bin Zayed, Crown Prince of Abu Dhabi and Deputy Supreme Commander of the UAE Armed Forces, and Brazil's President Jair Bolsonaro met at the Presidential Palace on Sunday.
Mr Bolsonaro was greeted at the gates with an official military reception, including a 21-gun salute. Children waving the flags of the UAE and Brazil lined the palace halls.
"We welcome Jair Bolsonaro, President of Brazil, as our guest to the UAE and hope that this visit will enhance friendship, co-operation and joint action between our two friendly nations," Sheikh Mohamed tweeted.
He said the two discussed ways to enhance bilateral co-operation, co-ordination and joint efforts to bolster regional and world security, stability and development.
A lunch was then in honour of the Brazilian leader, then Sheikh Mohamed and Mr Bolsonaro witnessed the signing of agreements.
These included a comprehensive strategic partnership signed by Sheikh Abdullah bin Zayed, Minister of Foreign Affairs and International Co-operation, and Brazilian minister Ernesto Araujo.
Both defence ministries agreed on the exchange and mutual protection of classified information and material.
Other deals included a strategic partnership on defence product development, production and commercialisation, and a UAE-Brazil fund for strategic co-operation and expansion of the defence sector's productive capacity.
Agreements in artificial intelligence, environment and trade were also signed.
Mr Bolsonaro and Sheikh Mohamed then met Brazilian and Emirati jiu-jitsu players at the Presidential Palace.
A separate meeting was also held with Sheikh Mohammed bin Rashid, Vice President and Ruler of Dubai.
Mr Bolsonaro, 64, arrived in Abu Dhabi on Saturday afternoon from Beijing for a three-day official visit. He leaves for Qatar on Monday and is due in Saudi Arabia later in the week.
Earlier on Sunday, he attended the UAE-Brazil Business Forum where he invited Emiratis to invest in his country.
On landing at the Presidential Airport on Saturday, Mr Bolsonaro visited Wahat Al Karama and laid a wreath at the Martyrs’ Monument.
The Brazilian leader toured Sheikh Zayed Grand Mosque, being briefed on its history and architecture by Dr Yousif Al Obaidli, director general of the mosque's centre.
Much of his visit to the region is likely to focus on building economic links between the Gulf and Brazil, with more announcements in energy, defence and infrastructure expected.
