Brazil's President Monday highlighted the success of her plan in thwarting organized crime along the border.

Dilma Rousseff said in her weekly radio show, "Breakfast with the President," that authorities have seized more than 3,650 tons of drugs and 2,200 firearms in a year and a half since the Strategic Border Plan was launched.

"Even though public security is a responsibility of the states, in accordance with the Constitution, the federal government must take part in the improvement of public security through special programs," she said.

Brazil's vast size and 16,000 kilometers of borders, much of it in sparsely populated and heavily forested areas, make patrolling the borders a particular challenge that requires firm government action and constant vigilance, she said.

Rousseff stressed the importance of joining forces with neighbors, adding that Brazil has border agreements with several countries, such as Colombia, Bolivia and Peru.

"With actions such as the Strategic Border Plan, we can build, along with neighboring countries, a solid network of border protection, fighting drugs and weapons trafficking, and organized crime," she said.
