The US and Brazil have signed a new defence cooperation agreement in an effort to enhance the security partnership between the two countries.

Under the accord, both countries will expand their defence cooperation in areas such as research and development, logistics support, technology security and acquisitions.

The agreement also covers information exchange of operational experiences, defence technology and peacekeeping operations and more combined training and joint military exercises.

US Defense Secretary Robert Gates said that the agreement formalised the growing security partnership between the US and Brazil, while establishing a framework to build on that relationship.

“This agreement will lead to a deepening of US-Brazilian defence cooperation at all levels and will demonstrate how much more effectively we can confront shared security challenges when we work in partnership,” he said.
