Brazilian real
China is increasing investment in Brazil, with financing oil exploration to repairing railways. The repair of railways and infrastructure came ahead of the Rio Olympics in 2016. There is also a trade phase from raw materials to heavy equipment and industrial goods. The two countries have also signed a currency agreement that will include up to $30 billion worth of Chinese Yuan and Brazilian real. This deal was signed to provide an alternative currency to the US Dollar with respect to the Chinese Yuan. China is considered Brazil's largest trading partners.
