in june 2015, president barack obama and brazilian president rousseff met nearly two years after rousseff canceled a rare state visit to washington following revelations that brazil was a target of american spy programs. u.s. was looking for bilateral trade and investment since china has overtaken the u.s. as brazil's largest trading partner. rousseff traveled to new york to meet with investment bankers and to silicon valley to drum up business for brazil's information technology industry. relations between the u.s. and brazil have since improved, and indeed the u.s. remains the leading investor in brazil both in fdi and in number of m&a transactions
