BRASILIA, Dec. 3 (Xinhua) -- Brazil and Germany signed a cooperation agreement Thursday for 2014 World Cup and 2016 Olympic Games to be held in Brazil.

    The agreement provides the expansion and modernization of infrastructure in Brazil, and the transfer of experience in public security, acquired by Germany for hosting 2006 World Cup.

    "We will teach what Brazil wants to learn. It is important that there is cooperation between fans and police," said German Chancellor Angela Merkel during a press conference after meeting with President Luiz Inacio Lula da Silva in Berlin.

    She said officers from all countries that participated in the 2006 World Cup went to Germany to support the safety of the event. According to Merkel, it has made contact with fans easier.

    The German chancellor also cited the transmission of the games on giant screens mounted on the streets of the cities that hosted the event, which could be done also in Brazil in 2014.

    President Lula admitted "problems generated by social issues", but defended Brazil as host of the 2014 World Cup and 2016 Olympic Games.

    He attributed the success of World Cup to the "extraordinary nature of the Brazilian people", but warned that the outcome of the final match may cause "a wee problem" on security.

    "We have the trauma of 1950 (World Cup), when we beat all the teams but we lost to Uruguay in the final. (In 2015) If we are in good situation, and lose in the final, I do not know how fans will behave," joked the president.
