Pretty much every remotely developed country is capitalist. The wealthiest country with a non-capitalist economy is Cuba or Turkmenistan, depending on where you draw the line.
The context of this discussion is Brazil and the intentions of the socialist Brazilian government. Are you claiming that the socialist party in Brazil intends to dismantle capitalism? In case you are unaware, countries can have capitalist economic systems and still have significant socialist traits like: large public sectors, state enterprises for natural monopolies and important industries, subsidized education and healthcare, etc.
Uhh, China...
Also depends on how you define capitalism, and whether you consider Socialism with Chinese Characteristics to be capitalist.
