Competing visions for Mexico's future were on display at the country's final presidential debate. Four candidates are standing in the July 1st run-off. Three-time candidate Andres Manuel Lopez Obrador has a wide lead, according to most opinion polls. Some compare his agenda to that of US President Donald Trump. CGTN's Franc Contreras has more from Mexico City.

The economy and development were the focus of Mexico's third and final candidates' debate. The front-runner, Andres Manuel Lopez Obrador, a former Mexico City mayor, displayed confidence. The other candidates attacked him. Lopez Obrador said it's not his fault they are trailing far behind. During the debate, he mentioned the names of his possible cabinet officials if he wins, and said he'll try to salvage the North American Free Trade Agreement in talks with the U.S. president.

ANDRES MANUEL LOPEZ OBRADOR MEXICAN PRESIDENTIAL CANDIDATE "I will work to maintain NAFTA. If that's not possible, it will not be the end for Mexico. Our country has many natural resources and a hard-working population. The only thing missing, and we'll have it soon, is a good government."

All four candidates for the Mexican presidency agree - corruption is the main impediment to economic growth in the country.

RICARDO ANAYA MEXICAN PRESIDENTIAL CANDIDATE "Ending corruption requires a commission to directly investigate the president of the Republic. Because I say this, others attack me. I tell them I am not afraid."

This is Lopez Obrador's third bid for the Mexican presidency. He now appears to be moderating his position on the economy. Still, analysts say he and Donald Trump share the idea that economic nationalism is the way forward.

RICARDO PASCOE, ANALYST POLITICAL STUDIES CENTER, AUTONOMOUS NATIONAL UNIVERSITY "He represents a proposal to go against the globalization of the Mexican economy and to increase the intervention of the Mexican state in the economy, much like what happened in Mexico in the 1960s."

The campaign closes in two weeks. Voters will choose their next president on July 1st. While the polls give Lopez Obrador a more than 20-point lead ahead of the second-place challenger, polls also indicate that a large number Mexican voters are still undecided.

FRANC CONTRERAS MEXICO CITY "Observers say it's that block of undecided voters that is the only thing standing between Lopez Obrador and the Mexican presidency. FC, CGTN, Mexico City."
