Paraguay has been hailed for its "impressive achievements" in trying to meet the UN's anti-poverty goals also known as the MDGs.
UN Secretary-General Ban Ki-moon expressed his appreciation to President Horacio Manuel Cartes Jara on Wednesday in the country's capital Asuncion.
The country's leadership has made progress in reducing poverty and inequality, as well as fighting drug trafficking, the Secretary-General said.
Ana Carmo reports.
The last UN Secretary-General to visit Paraguay was the late Dag Hammarskjöld in 1959.
The South American country has come a long way since then, Ban Ki-moon said.
Paraguayans enjoy better access to education and health care and more families have access to clean water and sanitation.
"This is very meaningful for me to visit Paraguay in this very auspicious year. We are working on three priorities. First we had to meet the targets of the Millennium Development Goals and for which I really appreciate for your very successful achievement."
The UN Secretary-General also praised the leadership for contributing troops to UN peacekeeping missions in eight countries around the world.
