In the closing ceremony on Saturday, Yucatan state Governor Mauricio Vila Dosal, praised the success of the meeting and the experiences the event would leave back for the state.
Dosal told a 3,000-strong crowd at the International Convention Centre that "all of us can make a difference and play our small part for world peace".
"We can do it with small individual action, starting from our house, friends, district and city. Then they multiply. Sending a powerful message, not just to our brothers but to the entire world," he said.
Representing the youth of the world, a group of youngsters vowed to defend all liberties including the freedom of expression.
They also committed to continue fighting for nuclear disarmament, and highlighted the role of education as the most powerful tool for establishing peace.
Reading out the final declaration of the summit, called the "Merida Declaration", the 2011 Nobel Peace Laureate from Liberia, Leymah Gbowee, called for a new understanding of the concept of peace.
She said that any threat to the well-being of anyone or the environment, affected all of us and urged everyone to leave a "footprint of peace" and contribute to making a more "just, peaceful and sustainable world".
The closing ceremony was also attended by famous Puerto Rican popstar Ricky Martin, who was honoured with a pigeon memento at the summit, symbolizing peace.
On the same night, Martin performed in front of a crowd of 25,000 people at the iconic Monumento a la Patria (monument to the Fatherland) in the Paseo de Montejo, the landmark street of Merida.
