Oh i agree with you, though i must say that trade with China will increase as long as the State of China keep buying commodities because the agribusiness sector has captured the Brazilian State and has been able to get massive funding for their activities. They have the majority of the congress. Like 2/3 of all politicians in Brasília are linked to agribusiness industry.
Yeah, they do have the laws and regulation but just don´t apply it. In theory they need to check if the farmer has propriety of the land and that they are authorized to farm in that land but the banks rarely do so.
