Justice Minister Luiz Paulo Barreto made the comments as Rio de Janeiro tries to contain a surge in violence, with gang members blocking roads and setting cars on fire in the city expected to host the World Cup final four years from now.
Barreto downplayed the recent concerns, saying security will reach its maximum level during the World Cup.
"We will be at an advanced level, with the police properly prepared," he said in the opening of a three-day meeting with government officials, local authorities and FIFA executives in the nation's capital. "The competition will take place in an environment of a lot of peace and tranquility."
